PLANTS COLLECTED BY DR. GAMBEL. 153 
A very distinct species, much-branched from the base and rather decumbent. The 
leaves smooth, narrow, and deeply emarginate, petioles about an inch long. 
Peduncles often exceeding the leaves, terminating in short, oval, dense spikes or 
heads, of nearly sessile small flowers, scarcely exserted beyond the calyx, deeply 
divided, and thickly clothed, almost hidden under a mass of rough black and white 
hairs, the segments subulate, but appearing obtuse with a tuft of hairs, very soon 
dividing above nearly to the base; bractes minute; vexillum oval, with a broad 
embracing claw; wings small and obtuse as well as the keel. The legume scabrous, 
oval, obtuse, dark grey, with a deep introflected suture, the cells one-seeded, the 
seed obcordate. Style slender, stigma capitate. : 
Has, On the island of Catalina, in Upper California. Flowering in February. 
A. *NIGRESCENS. Annual; nearly erect and much branched; stipules ovate, acuminate ; leaflets cuneate- 
linear, deeply emarginate, nearly smooth; flowers ochroleucous, in short oval spikes, at length 
nodding ; segments of the calyx subulate, acute, clothed with shortish black hair; legume ovate, acute, 
and villous, a little exserted ; cells one-seeded. 
Has. With the above, which it greatly resembles, but different in the calyx and 
pod; flowers less crowded and pedicellate, the calyx not so deeply divided, nor 
clothed with such long rough hairs ; bractes minute, chaffy, subulpta: stipules partly 
united at the base. 
PHLOX. 
P. *pryomwEs. Densely ceespitose, very small ; leaves closely imbricated in four rows, the ciliar pubescence 
extending beyond the points of the dhiiptisieculets, very acute short leaves; flowers scarcely 
exserted ; segments of the calyx obtuse ; those of the corolla cuneate, entire. 
Nearly allied to P. muscoides, but distinguishable by forming separate imbricated 
branchlets, and by the leaves being so short as to be buried in the down of the 
margins of the leaves. 
Has. On the dividing ridge of the Rocky Mountains. (Nuttall.) 
rg 
. “Nana. Dwarf and many-stemmed ; viscidly pubescent ; leaves rather long and linear, acute, the upper 
ones alternate; peduncles few, from the terminal branches, and as well as the calyx pilose; flower 
exserted, with the tube twice the length of the calyx sexments; border of the corolla longer than the 
tube, segments cuneate, emarginate. 
Flower large and red. Stems many from the same perennial root, four to five 
inches high; the lower leaves one and a half inches long, from one to twolines wide, 
quite flat, and more or less clothed with a small glandular pubescence. Flowers few, 
and as large as any in the genus, segments of the calyx linear and acute ; the tube of 
the corolla about twice its length. Corolla more than an inch across. Cells of the 
ovarium two-seeded. 
Has. Rocky Mountains, near Santa Fé.
