in Bentham and Hooker's Genera Plantarum, is clearly inseparable from Tommasinia, as those authors have indicated, and so to be referred to Peucedanum.

GARRYA BUXIFOLIA : foliis parvis ovato-ellipticis mucronatis crassis integerrimis supra mox glabris nitidis subtus argenteo-sericeis; spicis fœmineis pendulis brevibus, bracteis alte connatis plerisque unifloris; ovario glabro. A low shrub, on the Red Mountains, Mendocino Co., Bolander. Only the female plant. Leaves about the size of those of Box, glossy bright green and glabrous above as soon as they are grown, whitened beneath with a very fine and close silky pubescence which seems scarcely if at all deciduous with age, almost veinless. Female spikes nodding from the first, simple and short, seldom much longer than the leaves. Pedicels very short and included in the truncate-connate bracts; the calyx-teeth obsolete.

GARRYA FREMONTII, Torr. Bot. Whippl. A specimen in fruit found by Mr. Bolander "in a tavern on the Sonora road" in January, 1866, has the leaves oftener obtuse or retuse; the fruiting spikes erect, with bracts like those of the male. Berries glabrous, very shortpedicelled the two short calyx-teeth manifest.

LONICERA BREWERI (Gray, in Proceed. Am. Acad. 6, p. 537, char. emend.): caule erecto; foliis brevi-petiolatis ovalibus utrinque rotundatis seu majoribus pl. m. acuminatis basique subacutis membranaceis cum ramulis junioribus pubescentibus, pube brevi molli; pedunculis floribus vix duplo longioribus; bracteis bracteolisque consimilibus minimis rotundatis cum basi ovariorum coadunatorum connatis obsolescentibus; corolla lurido-purpurea campanulata late gibbosa ultra medium bilabiata, fauce ad staminum insertionem styloque villosissimis. Collected at the Mariposa Grove, Bolander, larger and more developed than Prof. Brewer's specimens from Mount Dana. [Also by Prof. Torrey, at Donner's Pass, &c.] The leaves in the present specimens 14, or the larger and later ones 2 inches in length, and disposed to be acute at both ends or acuminate. Ovaries most commonly united to or near the summit, the short calyx-teeth usually blunt. The present well-developed specimens show it is not L. nigra, nor even L. Chamissoi, but the Mandchurian L. Maximowicii, Rupr. to which this is most nearly related. In that, however, the pubescence is much more sparse and pilose; the leaves more ovate and taper-pointed, with veinlets conspicuously reticulated; the peduncles much longer; the ovaries longer, tapering, and less united; the style more hairy, &c.

GALIUM PUBENS: perenne, undique pube densa patente cinereum ; caulibus (ultrapedalibus) adsurgentibus paniculato-ramosis inermibus; foliis quaternis quinisve ovatis vel oblongis (lin. 4-6 longis) fere muticis uninerviis secus margines costamque magis hispidulis; cymulis foliosis paucifloris, pedicellis fructiferis deflexis; corollis albidis vel carneis raro 3-5-fidis; fructu ut videtur carnoso, immaturo pubero. Yosemite Valley and adjacent mountains, Bolander, Torrey. The specimens collected by the former have perhaps only male flowers, on very short pedicels; those collected by the latter have fertile flowers, on pedicels mostly twice the length of the flower and fruit. The pubescence, although soft and velvety to the touch, is hispidulous, but not uncinate, although rather hispid on the margins of the leaves; the angles of the stem not at all armed or roughened.

GALIUM BOLANDERI: glabrum; caulibus e radice perenni ramossimo diffuso (ultrapedali) ramulisque fere lævibus; foliis quaternis lato-linearibus uninerviis margine rariter scabro-hispidulis (3-5 lin. longis); paniculis laxe floribundis; pedicellis flore purpureo brevi oribus vel æquilongis; fructu (immaturo) subgranulato glabro. — Sierra Nevada, on the Mono Trail, Bolander. - Flowers small: the corolla only a line or a line and a half in diameter, apparently deep dull purple.

GALIUM ACUTISSIMUM: scabrido-puberulum, inerme caule gracili ramoso; foliis quaternis (lin. 3 longis) ovato-lanceolatis seu lanceolatis valide uninerviis sensim in cuspidem rigidum acuminatis; cymulis paucifloris; floribus albis brevissime pedicellatis; ovario glabro. — Between the Rio del Norte and New Mexico, Dr. Newberry. A very small-flowered species, remarkable for its gradually attenuated, cuspidate, rather rigid leaves.

BRICKELLIA INCANA: tomento implexo (ætate subdeciduo) dealbata; foliis ramorum alternis subcordatis vel ovatis sessilibus fere integerrimis basi subtrinervatis; capitulis ramos terminatibus breviter pedunculatis multifloris; involucri pluriserialis squamis obtusis, extimis ovatis, intimis linearibus; acheniis sericeis. Providence Mountain, in the Mohave district, 1861, Dr. J. G. Cooper. Only a single specimen, which wants the lower part of the stem. Leaves rather thin, the largest present less than an inch long, those on the flowering branchlets barely half an inch long. Heads single on the branchlets, even larger than those of B. lanata (an inch long, very many-flowered), the down finer and whiter, completely hiding the veins.

LESSINGIA LEPTOCLADA: floccoso-lanata, demum glabrescens, haud viscosa; caule erecto virgato superne ramos floridos sæpius corymbosos filiformes proferentibus; foliis infimis spathulatis subdentatis, superioribus lanceolatis linearibusque integerrimis basi brevissime sagittatoadnatis, ramorum parvis nunc raris in bracteas subulatas transeuntibus ; capitulis 520-floris solitariis bi- quinisve ramulos seu pedunculos terminantibus; involucri squamis lanceolato-linearibus acutatis mucronatis; corollis consimilibus purpureis, limbo æqualiter 5-partito; pappo corollæ tubum adæquante; radice (ut in omnibus sp.) annua. - Tres formæ admodum diversæ, ut videtur colligendæ :- TYPICA, 1-2-pedalis, capitulis 18-20-floris; involucro turbinato pluriseriali, squamis exterioribus gradatim brevioribus; ramis floridis gracillimis nunc simplicibus apice 1-3-cephalis, nunc proliferis pedunculis filiformibus corymbosis.Yosemite Valley, in sandy soil, Bolander. [And now received from the collections of Bridges and Torrey, and in a collection from Dr. Kellogg, said to be from near San Francisco.]

Var. MICROCEPHALA: sesqui- bipedalis; caule foliisque caulinis (argute dentatis rigidioribus) denudatis leviter glanduloso-scabridis ; ramis floridis filiformibus effuse paniculatis decompositis; capitulis parcis lin. 3 tantum longis involucro 5-floro; turbinato. On Bear Mountain, Dr. Torrey, 1865. I take this to be a form of L. leptoclada, probably from a more exposed station, and with depauperated inflorescence.

Var. TENUIS: 3-7-pollicaris; capitulis paucis 5-7-floris; involucro angusto e squamis paucioribus attenuatis minus imbricatis. - Yosemite Valley, with the typical form, of which, as Mr. Bolander did not distinguish the two, I infer it to be a remarkable depauperate state. But Dr. Torrey, who likewise collected it, regarded the three plants as wholly distinct species. Further observation will determine. The corolla in all is apparently light purple or whitish, as in all the other species except L. Germanorum, where they are yellow the lobes 2 or 3 lines long, oblong, becoming linear, their margins induplicate in æstivation up to the nerves (as in the others): inner flowers at length probably as large as the outermost: genitalia included: appendages of the style tipped with a prominent cusp much exceeding the bristles.

CORETHROGYNE SPATHULATA: caulibus cæspitosis decumbentibus apice vel ramis paucis adscendentibus foliosis monocephalis; foliis obovato-spathulatis versus apicem serratis, superioribus ovalibus oblongisve, summis in bracteas lineares transeuntibus; capitulo pro genere maximo; involucro hemisphærico; squamis linearibus vel subspathulatis

acutis glandulosis subæquilongis disco æqualibus; paleis inter flores nullis. On the coast at Shelter Cove and at Fort Bragg, Humboldt Co., Bolander. "Forming large patches or tufts; the stems lying on the ground, only the heads rising above the grass." Ascending stems or branches a foot or less high, covered like the foliage with the floccose cottony down of the genus. Leaves 2 inches long. 6-10 lines wide, thin. Heads 14 inches or more in diameter, including the numerous violet-purple rays. The narrowest-leaved specimens might pass for the broadest-leaved form of the variable C. filaginifolia, but the heads are like those of C. Californica, only still larger. From the habit, the white-cottony leaves, and the showy heads of flowers, this would be a very desirable acquisition to the gardens.

ASTER CHILENSIS, Nees, common about San Francisco, was doubtless collected in California by Hænke, and not in Chili, where, apparently, it does not occur. So that Nuttall's name, A. Durandi, distributed with specimens, but not published, had better be substituted.

ASTER (ORTHOMERIS, Torr. & Gr., Xylorhiza, Nutt.) ANDERSONII (Erigeron, Celmisia, Andersonii, supra, 6, p. 540): lana tenui mox decidua glabratus; caulibus e rhizomate nudo adsurgente erectis simplicissimis monocephalis; foliis gramineis linearibus coriaceis sæpe nitidis 3-5-nerviis (angustioribus fere uninerviis), radicalibus spithamæis, caulinis brevibus in bracteas subulatas sensim decrescentibus ; capitulo nudo hemisphærico (-poll. lato); involucri subtomentosi squamis lineari-lanceolatis acutis subherbaceis laxis 2 – 3-seriatis subæquilongis; ligulis oblongis (cæruleis vel purpureis); styli ramis fl. herm. longe tenuiter subulatis, parte hispida terminali quam stigmatosa 3- 4-plo longiori: acheniis oblongis villosis 4 - 6-costatis; pappi setis subæqualibus barbellulatis. - Nevada, Carson City, Dr. C. L. Anderson. California, Lake Tenaya in the Sierra Nevada, alt. 8,000 feet, Prof. Brewer. Westfall's Meadows in the Yosemite, 8,000 feet, and in meadows on the Tuolumne, 9,700 feet, smaller and smoother specimens, H. N. Bolander. The form from the highest station has the radical leaves only 2 to 4 inches long and barely a line wide; the others of Bolander have the slender flowering stems 6 to 9 inches high, and the conspicuously nerved Xyris-like radical leaves 2 lines wide. Not satisfied with my former reference of this plant to Erigeron, I now perceive that its pappus is neither scanty nor uniserial, and that it must rank with Nuttall's Xylorhiza, Aster Xylorhiza, Torr. & Gray Fl.

ASTER TORTIFOLIUS (non Michx.) Aplopappus tortifolius, Gray, afterwards Townsendia (Megalastrum) tortifolia, Gray, and the related A. WRIGHTII, which had also been referred to Townsendia, are both Asters of this Xylorhiza section.

ERIGERON SUPPLEX: humile, subvilloso-pubescens; caulibus e basi decumbente adsurgentibus simplicissimis apice nudo monocephalis ; foliis crebris integerrimis spathulato-lanceolatis summisve linearibus sæpe glabratis hirsuto-ciliatis; involucri squamis linearibus acuminatis dorso villosis discum adæquantibus laxis; ligulis nullis; corollis fl. disci marginalium rariter difformibus 2-4-dentatis ; acheniis hispidulis binervatis ; pappo e setis barbellato-scabris corolla paullo brevioribus setulisque nonnullis brevibus. - Roadside near Mendocino City, Bolander. I have also a specimen collected by Dr. Andrews, the station not recorded. Stems 3 to 6 inches long, apparently numerous, and spreading from a perennial root. Lower and larger leaves little over an inch in length and 3 lines in width, tapering into a petiole-like base. Head about half an inch in diameter, very many-flowered; the yellow disk flowers commonly all alike and perfect; sometimes a few of the outermost a little enlarged, and, as it were, essaying to become ligulate. Tips of the style very obtuse.

APLOPAPPUS (STENOTUS) ACAULIS Stenotus acaulis, Nutt., a Rocky-Mountain species, was collected on Mount Davison, Nevada, by Mr. H. G. Bloomer.

APLOPAPPUS (PYRROCOMA) WHITNEYI: late cæspitosus, glanduloso-scabridus; caulibus (ultrapedalibus) tenuiter pubescentibus usque ad apicem æqualiter foliosis; foliis oblongis subamplexicaulibus venulosis grosse argutissime dentatis, imisve angustioribus integrioribus; capitulis paucis subpaniculatis; involucro 20-25-floro oblongo-campanulato, squamis lanceolatis acutis appressis; ligulis 6-8 angustis discum paullo superantibus.- Mono Trail and Sonora Pass, in open woods, alt 9,000 feet; grows in large tufts, Bolander. This well-marked new species (named for the Director of the Survey) has the foliage of a Grindelia or of Aplopappus Nuttallii, and few or several rather small heads. The leaves are scarcely coriaceous, an inch or an inch and a half long, acute or obtuse, all but the lower beset with sharp teeth even to the clasping or half-clasping base. Peduncles seldom longer than the heads or the subtending leaf, terminated by one to three more or less foliolose bracteate heads; these three fourths of an inch long in fruit. Scales of the involucre few-ranked. Branches of the style, 45
