Most nearly allied to T. Harneyensis Howell, from which it is at once 

 separated by its pubescent leaves, sessile flowers (which are early, not tardily, 

 reflexed) , and glabrous calyx tube and ovary. 



Macbride's no. 967, from Jordan Valley, Owyhee County, in moist loam 



soil, June 22, 1911, is the type. 



Lupinus tenuispicus, n. sp. — Silvery-silky, with loose, copious, 

 somewhat spreading and tangled hairs: perennial, in dense clumps 

 on a woody caudex, 3-7 dm. high: stems rather slender, sparingly 

 branched: radical leaves on slender petioles 1-2 dm. long; leaflets 

 6-9, narrowly oblanceolate or nearly linear, 4-6 cm. long; cauline 

 leaves similar, shorter-petioled and (above) sessile: spikes slender, 

 crowded, 5-15 cm. long: bracts small, linear-lanceolate, somewhat 

 shorter than the nearly sessile calyx : calyx barely gibbous at base, 

 about 5 mm. long: flowers blue: standard nearly orbicular, the 

 blade pubescent on the back with fine long hairs (only visible 

 under a good lens), 6-8 mm. long, sharply emarginate at apex; 

 wing petals oval, on very short claws; keel petals small and deli- 

 cate, the blade semi-ovate, on a claw half as long: pods very short, 

 1-3-seeded, pubescence as on the rest of the plant. 



I can find no described species in this range having the very slender and 

 crowded spikes, the small apparently glabrous petals, and the short few-seeded 

 (often only one) pods of this form. 



No. 203, by Miss June Clark, from Tamarack, in the mountains of 

 Washington County, Idaho, August 8, 191 1, is the type. 



Astragalus nudisiliquus, n. sp.— Habit and appearance of 

 A. utahensis T. & G., the white indument even thicker and more 

 felted : caudex woody and freely branched : pod about 20 mm. 

 long, probably at first white woolly-hirsute, the indument at length 

 deciduous and disclosing the longitudinal striae, coriaceous-woody, 

 ovoid, flattened dorsally, the acute apex abruptly flexed, the dorsal 

 suture slightly keeled, the ventral somewhat sulcate. 



When the writer collected this and first examined it later, he took it for 

 granted that it was merely an over mature A. utahensis. On noting the char- 

 acter of the pod, however, it is evident that this is not the case. In that species 

 the indument is permanent, both sutures are inflexed, the body of the pod is 

 smaller, the apex is essentially straight, and, as a more strikingly character- 

 istic difference, the striae are transverse. In view of these facts it seems best 

 to put this species (which has no doubt passed for A. utahensis) on record.
