glaucum, Hook. Fl. Bor. Am. Scorzonella glauca, Nutt.— At Mark West's Creek, 1864 ; also Cloverdale, Sonoma Co., and Eel River, &c. Mendocino Co., in moist meadows, 1866 – 7, Bolander. The size of most of these specimens and the breath of the leaves made it doubtful if they belong to the species indicated by Sir Wm. Hooker; but a comparison made by Prof. Oliver with the solitary specimen preserved in the Hookerian herbarium (the leaves of which are not " canaliculate” but only longitudinally folded) assures me that they do. The leaves in the California plant are from 4 to 12 inches long, and from 1 to 2 wide, the midrib strong and broad. In specimens from Klamath Co., Oregon, Dr. Kronkrite, they are narrower, approaching to “ linearacuminate,” and the head scarcely larger than in S. laciniata. In Bolander's, the larger heads are an inch in diameter; the achenia fully 2 lines, and the pappus nearly half an inch in length. The Californian forms in general, being remarkably stout and tall, and so broadlyleaved, may be distinguished as var. PROCERA.

Calais BOLANDERI: subscaposa e radice tuberoso-fusiformi; caulibus basi parce ramosis scapisve gracilibus 1 - 2-pedalibus ; foliis linearilanceolatis elongatis integerrimis imisve subdentatis nunc laciniatis ; capitulis parvulis ante anthesin nutantibus; involucri squamis gradatim imbricatis e lanceolata vel ovato-lanceolata attenuato-acuminatis ; acheniis breviter linearibus (vix basi haud apice angustatis) glabris vel exterioribus puberulis ; pappi sordescentis paleis 8-9 brevibus ovatooblongis ex apice obtuso vel eroso-bidentato in aristam scabram achenio duplo longiorem productis. — Swamps at Fort Bragg, Mendocino Co., Bolander. — Leaves 8 – 14 inches long (including the tapering base or petiole), or those on the lower part of the stem 3 – 6 inches long, 3 to 6 lines broad, more commonly entire ; some denticulate or coarsely toothed, or, in one specimen, laciniate-pinnatifid. Involucre scarcely over half an inch in length. Achenia rather slender, barely 2 lines long, about thrice the length of the somewhat rigid paleæ of the pappus. The species is interesting from being, as it were, intermediate between Eucalais and Scorzonella.*

HIERACIUM BOLANDERI: H. venoso affine; foliis omnibus radicalibus sessilibus spathulato-oblongis vel oblanceolatis vix denticulatis infra glaberrimis glaucescentibus (nunc purpureis) supra marginibusque pilis longissimis laxis barbatis ; scapo filiformi (3 - 9-pollicari) cum capitulis 2 - 4 laxe corymbosis glaberrimis ; involucro cylindraceo 10-15floro eglanduloso biseriali, squamis exterioribus brevibus ; ligulis flavis ; acheniis fusiformibus apice leviter attenuato; pappo copioso sordido. — On Red Mountain, Humboldt Co., Bolander. Achenia 2 lines long, much longer than those of H. Scouleri, and fusiform, but less tapering upwards than those of H. Gronovii.

* HYPOCHÆRIS GLABRA, Linn., occurs in collections made by Dr. Kellogg and Dr. Gibbons in the vicinity of San Francisco, perhaps recently introduced from Europe.

CAMPANULA LINNÆIFOLIA: fere glaberrima; caulibus teneribus a basi ad apicem usque æqualiter foliosis subunifloris ; foliis ovalibus sessilibus (semipollicaribus) crenatis marginibus angulisque caulis setulis minimis retrorsis ciliolatis ; pedunculo erecto flore sæpius longiore ; calycis lobis lato-lanceolatis acutis tubo subhemisphærico duplo longioribus corolla campanulata vix ad medium 5-loba dimidio brevioribus ; sinubus nudis ; stylo incluso. — In swamps at Noyo, Mendocino Co., Bolander. A delicate little species. Corolla blue, half an inch long ; the lobes ovate, about 2 lines long.

CAMPANULA PRENANTHOIDES, Durand, Pl. Pratt. 1855 (evidently C. fili flora, Kellogg in Proceed. Acad. Calif., 1858, a far from appropriate name, and with a description which implies that the narrow corolla is barely 5-toothed, whereas it is really 5-parted in our specimens, the segments linear) : to this probably belong specimens gathered by Mr. Bolander in the Red Woods at Searsville, and by Prof. Brewer on the Upper Sacramento, &c.

ARCTOSTAPHYLOS bicolor (Xylococcus bicolor, Nutt., Comarostaphylis bicolor, Klotsch): erecta ; foliis coriaceis oblongis acutis breviter petiolatis integerrimis margine revolutis supra nitidis subtus cum racemis brevibus compactis ramisque junioribus incanis ; bracteis sepalisque ovato-rotundis squamaceis ; corolla obovato-urceolata ; filamentis villosis inferne vix dilatatis ; stigmate capitato crasso ; putamine 5-loculari nunc abortu uniloculari. - Near San Diego, March, 1862, Dr. J. G. Cooper, from whose specimens this character is taken. Nuttall found it near Monterey, and describes the bony putamen as one-celled; but I find five one-seeded cells.

ARCTOSTAPHYLOS NUMMULARIA : erecta (1 – 2-pedalis), ramosissima ; ramis cum petiolis brevissimis setoso-hirsutis; foliis crebris coriaceis (semipollicaribus) ovali-rotundatis nunc subcordatis nitidis venulosis muticis integerrimis raro mucronato-serrulatis ; racemis parvis fasciculatis glabris ; bracteis coriaceo-squamaceis pedicello dimidio brevioribus ; sepalis ovato-rotundis ; corolla ovato-globosa intus filamentisque glaberrimis ; aristis antheræ prælongis genuflexis; ovario tomentuloso. — On the plains near Mendocino City. Leaves rounded at the apex and seldom with any sign of a mucro. Flowers much smaller than those of A. tomentosa, white. Fruit unknown.

BRYANTHUS, Gmelin. Bryanthus & Phyllodocė (Salisb.), Don. The beautiful Californian species described below makes it necessary "to combine Phyllodoce with the far earlier Bryanthus. Among the characters to distinguish the genus from Menziesia are the foliaceous persistent bracts or leaves subtending the pedicels, as in Kalmia, &c., while Menziesia has strobilaceous flower-buds of scarious caducous scales, as in Azalea, &c.

§ 1. Corolla patenti-campanulata usque ad medium 5-fida ; stamina exserta.

BRYANTHUS BREWERI : glaber; caulibus adscendentibus rigidis ; foliis crebris linearibus lævibus margine arcte revolutis ; pedicellis plurimis minute glandulosis fore vix longioribus ; sepalis oblongo-ovatis glaberrimis; corolla rubro-purpurea; staminibus 10 (raro 7 - 8) styloque longius exsertis ; antheris.violaceis ; stigmate capitato. — High sierras of California, alt. 10,000 feet; on Wood's Peak, Eldorado Co., Prof. Brewer; near Donner's Pass, Prof. Torrey; and Mariposa Co., Bolander: also Mt. Hoffmann, Brewer (forma compacta, floribus primum capitato-congestis). In babit and foliage this resembles the following species, but is larger, the leaves sometimes half an inch in length, stems nearly a foot high; the bright “ rose-violet” or “ red-purple ” corolla half an inch in diameter when expanded, cleft to or rather beyond the middle. Anthers, as in the other species, opening by terminal chinks, but inclined to dehisce longitudinally.

$ 2. PHYLLODOCE. Corolla ore 5-dentata vel brevissime 5-loba, stamina includens,

* Campanulata, glabra, rosea, lobis reflexis : folia lævia margine revoluta.

BRYANTHUS EMPETRIFORMis. Menziesia empetriformis (Smith) & M. Grahamii, Hook. This (M. Grahamii, Hook., which appears really to be the M. empetriformis also) was collected on Mount Shasta hy Prof. Brewer. The style is either short-exserted or included on the same plant.

BRYANTHUS INTERMEDIUS, Menziesia intermedia, Hook., needs further elucidation. One specimen from Dr. Lyall's collection in the Rocky Mountains, with cylindraceous corolla, and narrower (but not acuminate) sepals, leads to the conjecture that the species is not wholly distinct from the foregoing.

* * Corolla ore contracta: folia marginibus haud revolutis pl. m. serrulato- seu glanduloso-scabris : sepala lanceolata.

Bryanthus Taxifolius, baving rose-colored or purple, rarely if ever blue flowers, had better have the Pallassian than the Linnæan name continued, that having been generally adopted under Phyllodoce.

BRYANTHUS ALEUTICUS (Menziesia Aleutica, Spreng., Bongard, pro parte, Phyllodoce Pallassiana, Don) is known by the glabrous filaments and (shorter, ochroleucous) corolla from

Bryanthus GLANDULIFLORUS (Menziesia glanduliflora, Hook.), which occurs in Sitcha. The former I have seen only from Unalaschka and Alaska.

ALLOTROPA, Torr. & Gray. Perigonium simplex, quam genitalia brevius, e phyllis (ut videtur sepalis) 5 rotundatis æstivatione imbricatis. Stamina 10, glabra: antheræ didymæ, æquales, extrorsum fere basifixæ, loculis rima brevi a basi versus medium extensa dehiscentibus, sub anthesi arcte inversæ introrsum pendulæ, modo Pyrole. Discus nullus. Ovarium globosum, 5-loculare : ovula in placentis axilibus innumera. Semina immatura scobiformia, e nucleo undique longe producta linearia. Stylus primum brevissimus, demum ovario plus dimidio brevior: stigma majusculum, depresso-capitatum. Herba spithamaa, brunnea, glabra, caule squamis inferioribus ovatis imbricatis superioribus lanceolatis obtusis patentibus tecto, spica virgata multiflora, floribus brevissime pedicellatis patentibus parvulis, superioribus bracteas lanceolato-lineares adæquantibus.

ALLOTROPA VIRGATA, Torr. & Gray, in Bot. Wilkes Exped. ined. A single and imperfect specimen was collected by Dr. Charles Pickering on the Cascade Mountains in Oregon. We now have it from Mr. Bolander (in the usual excellent specimens which he is accustomed to prepare), collected in Mendocino County, between Little Bear Harbor and Noyo, “ generally near Quercus densiflora.The characters of the proposed genus are briefly sketched in a synopsis of the known genera of Monotropeæ which I contributed to Prof. Newberry's Report, in Pacif. R. R. Survey, 6, Bot. p. 81. It was then supposed (from the examination of a single flower-bud) to be nearly related to Monotropa, section Hypopitys ; but the character, it will be noticed, has now to be entirely recast, and the genus claims its relationship to

Schweinitzia and to Pyrola. The anthers of Allotropa in the expanded flower much resemble those of Schweinitzia, except that, in place of the large orifice occupying the whole broad end of each cell, a slit which opens broadly extends from the extremity to near the middle. In view of this resemblance, and of Dr. Torrey's observation (which I have confirmed) that the anthers of Schweinilzia in the flower-bud are horizontal, so that one cell stands directly over the other, one may suspect that here also they are extrorse and basifixed in the early bud; but I have no evidence that it is so. And the earliest flower-buds which I have examined of Pterospora and Sarcodes show no indication of resupination. Two subulate bractlets which were thought to have been detected upon the original specimen of Allotropa are not seen in the good specimens now in hand. I presume that its simple perianth answers to the calyx of Schweinitzia, and that the corolla is wanting.

PLEURICOSPORA, Nov. Gen. Monotropearum. Perigonium duplex completum. Sepala 4-5, oblongo-lanceolata, petalis totidem discretis oblongis subconformibus alterna et dimidio · breviora, utraque (supra medium præsertim) margine laciniatofimbriolata. Genitalia petalis breviora, glabra. Stamina 8 rel 10 : antheræ lineares, invatæ, filamento filiformi complanato vix latiores, callo brevi retuso apiculatæ, loculis rima laterali leviter introrsa a basi ad apicem dehiscentibus, valvis fere æqualibus. Discus nullus. Ovarium ovatum in stylo crasso æquilongo attenuatum, uniloculare, placentis 4 - 5 parietalibus bilamellatis undique ovuliferis. Stigma depresso-capitatum. Ovula obovata. Capsula .... Semina ovalia, nitidula, testa nucleo conformi. – Herba glabra, 3 - 5-pollicaris, sæpius crassa ; squamis confertis imbricantibus, infimis ovatis margine erosulis, superioribus floralibusque ovato-lanceolatis margine scariosis erosofimbriolatis ; spica sæpius cylindrica dense multiflora ; floribus ut videtur albidis semipollicaribus bracteam adæquantibus.

PLEURICOSPORA* FIMBRIOLATA. — In or near the Mariposa Sequoia gigantea Grove, Bolander, sparingly collected. This interesting plant is most allied to the one which, in Newberry's Report, above cited, I described and had figured under the name of Hemitomes congestum, and which, as this generic name, given upon a wrong idea of mine as to the structure of the anther, is contradicted by the true character,

* The generic name alludes to the parietal placentation. VOL. VII.
