more) from the crown of each Hiizome, 3-4 dm. high, simple below% 

 branched above, the branches slender, leafy, barren, exceeding the 

 single mature raceme : leaves elliptic, oblong or broadly oblanceo- 

 late, mostly obtuse, 3—5 cm, long ; stipules broadly ovate or 

 rhombic below, narrower upward, the upper oblong, 2-3 cm, 

 long; petioles about as long as the stipules: raceme strictly ter- 

 minal on the main axis : calyx-tube campanulate, somewhat nerved 

 at the base, 5 mm. long, the lobes shorter : corolla unknown : 

 mature pods pubescent, 12-15 cm. long, about 7 mm. broad, cir- 

 cularly curved, usually forming a complete ring or the apex even 

 overlapping the base: seeds 7-10; the ovules somew^iat more 

 . numerous, 



. That it should be necessary to establish a third species in this 

 genus, from this state within a year, is a little singular but this 

 plant differs so radically that it can not be disposed of satis- 

 factorily in any other manner. In habit and pubescence it sug~ 

 gests T. argcntata Greene but in fruit character it is nearer T. rJioin- 

 bifolia Rich, though its circularly curved pod makes it distinct 

 enough from that. Then too the habitat of this is exceptional. 

 While. not strictly alpine yet it is more than sub-alpinc. It was 

 secured in the Ferris Mountains, among the rocks on the naked 

 slopes near their summits, at an altitude of fully 10,000 feet.

Anogra rhizomata 



Perennial : rhizome horizontal, long, semi-woody, moderately 

 thick, giving rise at intervals to short, obliquely ascending 

 branches : stems several, from the crowns of the branches of the 

 rhizome, divaricate-ascending, 1-2 dm. long, from pinkish to light 

 violet, puberulent : leaves from nearly entire to deeply plnnatifid, 

 ■linear-oblong in outline, the lower somewhat petioled, 3-5 cm. 



long, more or less hispid-ciliate and puberulent : flowers axillary,, 

 congested at the summit of the stems ; buds acute at apex, some- 

 times glabrate : calyx tips free, lobes shorter than the petals, usu- 

 ■ ally much shorter than the tube, throat not villous : petals white 

 or pink, sub-orbicular: capsule linear, somewhat angled, scarcely 

 tapering to the apex, 2-^^ cm. long, divergent or becoming de- 

 flexed. 



This and A. albicaidis resemble each other greatly in general 



ft 



aspect but the remarkable rhizome of the one is to be con- 

 trasted with the slender, vertical taproot of the other. The 

 obtuse buds and small, tapering capsule of the larger plant is to
