are thinner-leaved than in C. maculata, and with the uppermost leaves and the 3 - 5 superior pinnæ of the lower and radical leaves of simple leaflets (or sometimes the lower 2-lobed), giving the plant the aspect of a Sium.* The involucels are mostly of broader bracts and the fruit of rather broader outline than in C. maculata ; the ribs all very corky: carpophore 2-parted: transverse section of the seed orbicular. C. maculata, besides the difference in the leaves, and especially in their venation, has the marginal jugæ, as seen in cross section, very much larger than the others, and the seed either fat or decidedly concave on the face.
PIMPINELLA APIODORA : glabra, bi – tripedalis ; foliis ternato-decompositis, caulinis petiolo primario spathaceo, foliolis inciso-pinnatifidis trifidisve, segmentis oblongis vel subcuneatis incisis; involucellis e bracteis lineari-subulatis vel setaceis ; floribus albis nunc roseo tinctis; fructu late ovato subdidymo, jugis prominulis. — Rocky hills along the coast of California from Mendocino Co., Bolander, to San Francisco, Bolander, Kellogg, &c. Apparently not rare, it is singular that it has remained so long unnoticed. The fleshy root, stems, and seeds are strongly imbued with the odor and flavor of Celery. The fully mature fruit is yet unknown; but the form of the fruit and seed, the numerous vittæ, the absence of calyx-teeth, and the conspicuous pulvinate stylopodia indicate the genus ; which is new to this continent, excepting P. integerrima (Zizia integerrima, DC.), referred to it by Bentham and Hooker.
PODOSCIADIUM, nov. gen. Scandicinearum. Flores polygami, albi. Calycis dentes prominentes, tenues, scariosi vel petaloidei, subulati. Petala obovata, acumine inflexo vel involuto longo, ob costam superne impressam emarginata. Stylopodia brevia, conica. Fructus oblongus, a latere pl. m. compressus, ad commisuram haud constrictus, apice subcontractus, jugis filiformibus vel angustissimis, valleculis latis 1 – 2-vittatis. Semen facie late sulcatum, sulco linea centrali prominula percurso, sectione transversa reniformi. Car
* SIUM LINEARE, Michx. I must dissent from the statement in Benth. & Hook. Gen. Pl. p. 888, that in this “valleculis perperam 2 - 3-vittatis dictis "; both this and S. Carsonii being found on re-examination to accord with the characters assigned in my Manual, except that the vittæ are very seldom solitary, even in the dorsal intervals. I may add, as farther separating them from Apium, that both species have a manifest, but very attenuated, completely 2-parted carpophore.
pophorum bifidum. - Herbæ perennes, glaberrimæ, subsimplices; foliis pinnatim vel subternatim decompositis, segmentis linearibus angustis ; umbellis longe pedunculatis pluri-radiatis, terminali fertili, lateralibus masculis, involucris et involucellis e bracteis plurimis subscariosis linearibus seu lanceolatis setaceo-acuminatis. — A nearly allied plant, probably, is No. 6 of Hartweg’s Mexican collection, doubtfully appended to Oreomyrrhis by Bentham ; but it has a simple umbel and obtuse nearly plane petals.
PODOSCIADIUM CALIFORNICUM ( Chærophyllum ? Californicum, Torr. Bot. Whipp. Exped. p. 37): caule 3 – 4-pedali ; segmentis foliorum planis ; umbellis 9 - 12-radiatis ; calycis dentibus stylopodiis brevioribus ; petalis acumine involuto obtuso ; fructus jugis filiformibus obtusis ; semine sub vittis in valleculis solitariis magnis pl. m. sulcato. — Knight's Ferry, Stanislaus River, Dr. J. M. Bigelow.
PodosCIADIUM BOLANDERI: caule 2 – 3-pedali superne longe nudo ; foliis plerisque subradicalibus, segmentis angustissime linearibus fere filiformibus ; umbellis multiradiatis ; involucelli bracteis angustis tenuiter aristatis pedicellos subæquantibus ; calycis dentibus petalis acumine attenuato inflexo subdimido triplove brevioribus; fructus jugis angustissimis elevatis ; vittis in valleculis binis obscuris. — Mariposa Trail, Yosemite, Bolander. This cannot well be other than a close congener of the preceding : the only doubt comes from the pair of vittæ in the intervals, which, however, are rather obscurely marked in the thin pericarp, although the seed is well formed. Fruit much smaller than in P. Californicum, only a line and a half long; the ribs exceedingly narrow, but sharp and salient. Calyx-teeth ovatesubulate, as thin and delicate as the petals.
MYRRHIS Ş GLYCOSMA. (Glycosma, Nutt.) Fructus juga lavia, haud alæformia. Styli brevissimi. Involucellum nullum. Foliola pauciora, latiora, minus incisa.
M. OCCIDENTALIS (G. occidentale, Nutt.): subpuberula ; foliolis oblongis sublanceolatisve serratis raro incisis ; pedicellis fructiferis Aores sterilia subsuperantibus ; jugis fructus acutis.
M. BOLANDERI : subpubescens ; foliolis ovatis magis incisis ; pedicellis fructiferis floribus sterilibus brevioribus; jugis obtusis. — At Lambert's Lake, Mendocino Co., Bolander. Leaflets more numerous than in Nuttall's species, and more like those of Osmorrhiza. Pedicels of the fruit only a line and a half long. — Bentham and Hooker have characterized the genus Myrrhis upon M. odorata alone, and then added the American species without modifying the general diagnosis.
LIGUSTICUM (CYNAPIUM, Nutt.) APIIFOLIUM. Nuttall's two forms, Hall and Harbour's No. 218 from the Rocky Mountains, and the Californian specimens (some of them with leafless stems) may comprise two or more species ; but wholly mature fruit has been collected only by Nuttall. In this the seed is scarcely more concave on the face than in some genuine species of Ligusticum, to which genus Bentham and Hooker refer it.
LigustiCUM SCOPULORUM: L. (Conioselino) Fischeri affine ; mericarpiis parum brevioribus ovali-oblongis ; alis angustioribus crassioribus, intermediis et dorsali minus evolutis 1 - 2 sæpe obsoletis ; vittis perspicuis majusculis in valleculis omnibus 3 nunc in lateralibus 4 ; sectione seminum fere reniformi. — Santa Antonita, New Mexico, Dr. J. M. Bigelow, with ripe fruit; the plant enumerated in the Botany of Whipple's Expedition, p. 38, as Conioselinum Canadense. Also in the Rocky Mountains of Colorado Territory, being doubtless Parry's No. 156, and Hall and Harbour's 216 (at least in part), published as C. Fischeri. Apparently the same collected at Fort Steilacombe, Washington Terr., by Dr. Suckley. Fruit in size and shape intermediate between that of Conioselinum Fischeri of the Old World, which Bentham and Hooker refer to Ligusticum, and C. Canadense which (having the vittæ usually solitary in the dorsal and in pairs in the lateral intervals, and the carpels more orbicular) they remand to Selinum. Unless more definite distinctions can be found, it were better to unite Selinum with Ligusticum. (The Conioselinum from Ochotsk, in Rodgers's Expedition, mentioned by Bentham and Hooker, is probably the form or doubtful variety cited in the Flora Rossica and Flora Ochotensis under C. cenolophioides.)
LIGUSTICUM MONTANUM = Thaspium ? montanum, Gray, Pl. Fendl., Pl. Wright, &c., (referred to Ligusticum by Bentham and Hooker, but by their characters should be a Selinum,) has mericarps in some specimens almost orbicular, including the broad marginal wings, in others oblong-oval ; in both the strong vittæ are sometimes single, sometimes double. The foliage is very variable for one and the same species; but the form with long and slender divisions to the leaves shows fruit of both shapes.
ANGELICA LINEARILOBA : glabra ; caule valido ; petiolis prorsus spathaceo-dilatatis ; foliolis longe linearibus acutatis (1 – 2-poll.) inte
gerrimis nunc 1 - 3-dentatis seu lobo divaricato instructis in rachin marginatum decurrentibus ; involucro involucellisque subnillis ; fiorikus albis ; fructus alis disco angusto oblongo paullo angustioribus ; vittis semini adhærentibus, lateralibus geminis. – Ostrander's Meadows, Yosemite Valley, alt. 8,000 feet, Bolander. Stem 2 or 3 feet high. The nearly full-grown fruit, including the wing, is oval-oblong, about 4 lines long and 2) wide; mericarps flat. The stout root not sweet-scented.
ANGELICA BREWERI: glabra vel tenuiter puberula ; petiolis spathaceo-dilatatis ; foliis triternatis vel triquinatis; foliolis lato-lanceolatis argute dentatis (dentibus cuspidatis) reticulato-venulosis, lateralibus sessilibus basi inæquali hinc sæpe adnata ; involucro involucellisque nullis ; floribus albis ; fructu puberulo oblongo, alis crassis angustis ; rittis in valleculis lateralibus quandoque geminis ; semine facie concaro (sectione transversa lupata) dorso sub vittis sulcato. — Sierra Nevada, near Ebbett's Pass, and on the Big-tree road, alt. 6,000 feet, Prof. Brewer [and near Donner Lake, Prof. Torrey, with mature fruit). Stem apparently tall and stout. Fruit 4} lines long, with wings less than half the width of the disk, cellular, and as thick as the edges of the much-flattened seed: the vittæ large, adherent on the one side to the groove of the seed into which it is received, on the other to the thin pericarp.
Ferula CALIFORNICA=Leptotænia? Californica, Nutt. The mature fruit of this, now collected by Bolander [also by Prof. Torrey), but already quite well described by Torrey, in Bot. Whippl. Expl., is traversed with numerous conspicuous, although slender, often anastomosing vittæ, and the winged margin is no thicker than in some species of Ferula, to which this plant appears clearly to belong. Its dilated leaflets are in the manner of Narthex.
FERULA (LEPTOTÆNIA, Nutt.) DISSECTA, with vittæ obsolete, as in several Old-World species of Ferula, has usually, and in some of Nuttall's own specimens, an obvious involucre of many bracts; the fruiting pedicels very short.
FERULA (LEPTOTÆNIA, Nutt.) MULTIFIDA, if, as is likely, the plant in Spalding's Clear Water collection, has no involucre and longer pedicels to the flowers and fruit: the latter I have not seen full grown. There are some indications of one or two more species.
PEUCEDANUM EURYPTERA (Euryptera lucida, Nutt.), the good figure of which in the Mexican Boundary Survey, t. 27, is not cited
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 foemineis 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 13, 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.
