Aplopappus Bloomeri, A. Gray, Proc. Am. Acad. vi. 541 (1865). Ericameria erecta, Klatt, teste, A. Gray. Aster Bloomeri, O. Ktze, 1. c. 317 (1891). Nothing in the modern history of the asteroid composites was more arbitrary than the making the presence or absence of rays the dividing line between "Aplopappus" and "Bigelovia;" and the present plant is so intimately related to C. Nevadensis that I believe hybrids between them exist. This species is not to be referred to Ericameria, i. e., the amplified Chrysoma of this series of papers, because it has neither the involucre nor the styletips of that genus. Neither is it, as Gray described it, a glabrous shrub. It is very commonly found invested with the woolliness of the present group in some degree, at least when young; and the involucre, as well as the whole floral structure-long style-tips, claviform and merely toothed disk-corollas, etc.-is that of the present group, from which its few proper rays-1, 2 or rarely 3 or 4-can not in reason exclude it. In several particulars this and C. albidus are much alike.

Two South American shrubs or small trees, which Dr. Gray proposed to subordinate to his " Bigelovia,” are clearly distinct from this Chrysothamnus series by having broad revolute-margined coriaceous leaves that are conspicuously veiny, the veins almost pinnately divergent from the conspicuous midrib; by their thinnish obtuse closely appressed and regularly imbricated involucral bracts; their deeplycleft corollas with linear and spreading segments; their short and lanceolate style-appendages. To my view these are surely a genus, which may be called

NEOSYRIS.

PLANTS HITHERTO UNDESCRIBED.-I.

By J. BURTT Davy.

Lupinus eximius. Frutescent, 2-3 ft. high, young branches, bracts, and growing parts hirsute with long soft white spreading hairs: stipules broad and semiamplexicaul, adnate for about half their length, those of the lower leaves for more, the free part subulate: leaflets 7-9, silky on both surfaces with longish pubescence, oblanceolate, obtuse, ending in a cusp, 8-10 lines long, 12-24 broad: inflorescence about 1 in. broad, barely 1 inch in length when the lowest flowers open, but elongating to about 5 in.; bracts caducous 4-5 lines long, incurved and considerably exceeding the buds; pedicels stout, 3 lines long, pubescent; flowers light purplish-blue and white, wings and banner broad.

Plentiful on the highest ridge above Lake Pilarcitos, San Mateo Co., Calif., near the summit of the eastern slope, 20 April, 1895; my No. 1050. Type specimens preserved in the herbaria of the University of California and of Prof. Greene. A very handsome, free-flowering bush, noticeable for its large and delightfully scented flowers, the odor much as in L. propinquus and more delicate than in L. arboreus, in fact at once recalling the fragrance of a field of Trifolium repens in full bloom. The shortness of the inflorescence when the first flowers open is a marked feature.

Senecio Breweri. Perennial?, herbaceous, erect, about 2 ft. high with glabrous, sulcate stems: leaves apparently entirely glabrous; radical leaves tufted, rather long-petioled, lyrately pinnate with cuneate-obovate or subreniform, coarsely toothed leaflets, or deeply pinnatifid; upper cauline smaller, sessile and semiamplexicaul, laciniately 1-2-pinnatifid, the lobes toothed: inflorescence corymbose, peduncles and pedicels long; heads erect, 5-6 lines high, about 4 lines broad; bracteoles few and very short; involucral bracts

or even 1 line broad, 10-15 in number, apparently thin and lightly 2-ribbed, their broadly scarious margins overlapping in flower; rays few, broad, light yellow.

Gravelly slopes and hills of Alameda Co. and southwards in California; common. Type Prof. Brewer's No. 512 collected on the Geological Survey of California, 1862, and preserved in the herbarium of the University of California. At once distinguished from S. eurycephalus with which it has been confused, by the more numerous heads and corymbose inflorescence, the cut and apparent glabrousness of the foliage, and the broad involucral bracts. The leaves of S. eurycephalus bear remnants of tomentum even when the plant is fruiting: the involucral bracts are about 20 in number, narrow, with a thick fleshy midrib leaving a narrow sub-scarious margin; in flower they cohere somewhat, separating irregularly in fruit. The range of the latter plant is more northerly than that of S. Breweri and it appears to prefer the neighborhood of streams.

Senecio caulanthifolius. Stems 2 or 3 from a perennial rootstock, erect, simple, about 2 ft. high, clothed when young with very short sparse wool: radical leaves with long slender petioles, narrowly cuneate-ovate obtuse, to lanceolateelliptical acutish, coarsely and doubly crenate-serrate, roughish above with minute scurf; veinlets reticulate, flexuous: lower cauline leaves long-petioled, pinnatifid; upper smaller and more distant, sessile, semiamplexicaul, laciniate: inflorescence loosely corymbose; heads several; pedicels long; involucres 4 lines high, bracts about 15, broad, 2-ribbed, scarious margined, with few bracteoles, these about their length; rays broad.

Murphy's Camp, Calaveras Co., Calif., May 24th, 1895; my No. 1437. Type specimens in the herbaria of the University of California and of Professor Greene. Readily distinguishable from S. Breweri by the foliage and much longer pedicels.

Triglochin concinna. Rootstock perennial, stoloniferous: leaves 4 or 5, 4-6 in. long, usually less than 1 line wide, linear, half-terete, flattened and slightly grooved on the inside, flattened on both sides at the apex: scape slender, wiry 8-13 in. high sometimes attaining 17 in., not densely

flowered: stamens 6, in 2 series: fruits bluntly trigonous, not ribbed, 2–2 lines long, 1 line broad, ascending, on pedicels nearly the same length; cocca 6, free, all fertile.

Abundant in the salt marshes around San Francisco Bay, Calif., together with T. maritima; my No. 1116. Type specimens in the herbaria of the University of California and of Professor Greene. In drying for the herbarium the cocca are apt to become canaliculate on the back, and the shape of the fruit is entirely destroyed.

SPHÆRALCEA ANGUSTIFOLIA, G. Don, var. violacea. Size, aspect and general habit of Gray's var. cuspidata, but pubescence coarser and, on the stem, less abundant; bracteoles darker colored and much longer, in fact exceeding the buds, and in anthesis exceeding the calyx tube, corolla violet. My No. 36, collected at Painted Cave railroad station on the banks of the Rio Grande, Texas, March 12, 1893. Type specimen in the herbarium of the University of California.

NOVITATES OCCIDENTALES.-XV.

By EDWARD L. GREENE.

Delphinium leucophæum. Slender, erect, simple, 2 feet high, from a cluster of short and thick tuberiform roots; the whole plant puberulent, the stem retrorsely so: cauline leaves divided into 5 linear-cuneiform 3-cleft segments, all linear and callous-tipped: raceme rather long and loose, the pedicels all about an inch long or somewhat less: sepals rather small, oblong and obovate, yellowish white, the spur long, straight, ascending, acutish: lower petals conspicuously woolly-hairy, colored like the petals, the upper apparently dark blue or purple: follicles rather short, erect, puberulent: seeds small, elongated cubical, sharply angled.

Specimens in herb. Calif. Acad., said to have been collected somewhere in Oregon, by T. S. Brandegee.

Boisduvalia bipartita. Erect and simple, or with a few decumbent branches from the base, a foot high or somewhat less, the herbage pale and softly villous: leaves lanceolate and linear-lanceolate, or the floral ovate-lanceolate, all entire or obscurely and remotely denticulate: corolla white, each petal parted almost to the base into two unequal lobes, the smaller one about two-thirds the length of the other: capsule villous: seeds few and large.

Sandy dry bed of the Arroyo del Valle, Alameda Co., California, 14 June, 1895, A most remarkable species, on account of the regularly unequal lobes of the very deeply parted petals; the open corolla invariably appearing as if composed of eight petals, four long and four short.

Aster leucanthemifolius. Annual or biennial, stout, rigid, erect, a foot high or more, somewhat divaricately and quite loosely branching; herbage pale and appearing glaucous, but really cinereous-puberulent as seen under a lens: lowest leaves 2 inches long, spatulate-obovate, coarsely and deeply crenate-serrate, the teeth with a short rigid spinous appendage; cauline leaves similar but scattered and small, to 1 inch long: heads small; involucre turbinate, the racts with short herbaceous spinescent recurved tips: rays about 20, broad and short.

Southern Nevada, near Candelaria, at an elevation of 6000 ft., Shockley.

Aster inornatus. Apparently perennial, the several equal stems ascending, from a central tap-root and attaining the height of 2 or 3 feet; herbage pale, obscurely puberulent: leaves few, narrowly oblanceolate, remotely and slightly serrate-toothed, the cauline much reduced: heads shortpeduncled or subsessile on the upper part of the stem and along the few short virgate branches: involucre turbinate, 5 lines high; bracts very numerous, not spinescent but abruptly squarrose at tip, and with sessile glands along the edges: rays none: teeth of disk-corollas pubescent: pappus almost barbellulate.
