PLANTS COLLECTED BY DK. 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 introfiected suture, the cells one-seeded, the 

 seed obcordate. Style slender, stigma capitate. 



Hab. On the island of Catalina, in Upper California. Flowering in February. 



A. *NiGKESCENS. 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 vi'ith shortish black hair ; legume ovate, acute, 

 and villous, a little exserted ; cells one-seeded. 



Hab. 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, subulate : stipules partly 

 united at the base. 



PHLOX. 



P. *BiiYoiDEs. Densely cjespitose, very small ; leaves closely imbricated in four row^s, the ciliar pubescence 

 extending beyond the points of the oblong-lanceolate, 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. 



Hab. On the dividing ridge of the Rocky Mountains. (Nuttall.) 



P. *NANA. Dwarf and many-stemmed ; viscidly pubescent ; leaves rather long and linear, acute, the upper 

 ones alternate ; peduncles few, from the the terminal branches, and as well as the calyx pilose ; flower 

 exserted, with the tube twice the length of the calyx segments ; 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 two lines 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. 



Hab. Rocky Mountains, near Santa Fe.
