64 KRYTHEA. 



but smaller and more compact: leaves elliptic to oblong, obtuse or 



sub-acute, mostly, 5-7 pairs: scapes but little exceeding the leaves 

 even in fruit, mostly less than 1 dm. high ; purple spot on the keel 

 conspicuous: pod twice as long as the calyx, broadly oblong or 

 nearly elliptic with a short, straight, sharp point. 



This is the most compact plant of this genus that I have seen. 

 Collected but once, on a naked, red, gravelly hilltop which was 

 abundantly dotted with the sub-spherical clumps (single plants): 

 Point of Rocks, June 16, 1898, No. 4773. 



Aragallus involutus. Root habit of the preceding, the caudex 

 with short branches which are clothed with the more or less mem- 

 branous, nearly glabrous leaf-bases; scapes and leaves greenish, 

 very thinly strigose pubescent; leaves numerous from the crowns, on 

 slender petioles; leaflets 13-19, linear, with more or less involute 

 margins, 2-4 cm. long; scapes slender, curved-ascending or nearly 

 erect, 2-5 dm. high (including the long spike), from only a little ex- 

 ceeding the leaves to nearly twice as long; spike at length slender 

 and rather open; calyx canescently tomentose, about 1 cm. long, 

 longer than the linear-lanceolate bracts; corolla purple; the blade 

 of the standard broadly oval ; the wings narrowly ovate, entire at 

 the apex, its slender claw shorter than the blade; tip of the keel 

 comparatively long and slender; mature fruit not at hand. 



Through the courtesy of Prof Conway McMillan I have been 

 able to see a number of specimens of this excellent species. It was 

 collected at Acton, Meeker Co., Minn., June 1892, by Mr. W. D. 

 Frost, and has been distributed as Spiesia Lamberti (Ph.) 0. K. 



3. Stipules adnate to the petiole; leaflets numerous, sub-verticillate 

 in threes or fours; pod 2-celled. 



Aragallus splendens (Dougl.) Greene, 1. c. Oxytropis splen- 

 dens Dougl. in Hook. Fl. Bor. Am. I, 147 (1834). This truly 

 spleujSid species occurs in many mountain valleys ; it is so distinct 

 that it can not well be confused with any of the other species. 

 Though always well represented in herbaria yet the following may 

 be cited as typical: No. 4372, Willow Creek, July 1, 1898.
