§ 92. New Species of Plants, chiefly New Mexican. 



By Edward Lee Greene. , 



Astragalus Gilensis.— ^r^^//y^///; perennial; subcaulescent, ' 

 white-silky with a fine, closely-appressed pubescence; peduncles num- 

 erous, slender, scape-like, bearing a short, dense, subcapitate raceme ; 

 corolla 3 lines long, pale blue ; pod 3 lines long, coriaceous, silky- 

 pubescent, ovate, not obcompressed nor either suture at all im- 

 pressed. 



On a high summit at the mouth of the canyon of the Gila River, 



in New Mexico. April, i88r. 



Plant with the habit of A. Missouricnsis, but very much smaller 

 every way, and very distinct by characters of flower and fruit. y 



AsTRAG ALUS MoGOLLONicus.— .¥'^///W;^/ ; perennial, nearly 

 stemless, densely clothed with yellowish, woolly pubescence; pedun- 

 cles short, scape-like; racemes dense, subcapitate; flowers large, 

 greenish-yellow and purple; pod 4 lin*^^ '^"g' "early cylindrical, 

 completely 2-celled, hardly at all incurved, very densely white-woolly. 



Bleak, grassy summits of the middle elevations of the Mogollon 

 Mountains in New jV^exico, flowering in April, 1S81. 



As compared with its nearest ally, A. Bigelovii, the plant is a 

 dwarf, being barely a span high. Its still smaller pods are much 

 more densely woolly, and nearly straight in maturity, in which latter 



character, however, the species is at variance with the rest of the 



MoUissimi. 



/ 



PoTENTiLLA suBviscosA.— Ascending, a span to nearly a foot 

 high, clothed sparingly with straight, villous hairs, and with a denser 

 coat of short, viscid-glandular ones; leaves digitate ; leaflets 5, 

 cuneate-oblong, \—\ inch long, the margin with close, oblong, not 

 very deep lobes ;' cyme very loose; pedicels slender, an inch long, 

 deflexed after flowering; petals yellow, 4-5 lines long, nearly twice 

 the length of the calyx-lobes, and narrow; carpels about 12. _ 



On a dry southward slope of the Mogollon Mountains, flowering 



in April, 1881. . . 



A well-marked species, peculiar in having two so distinct kinds 



of pubescence as to make it both soft and clammy to the touch. 

 The narrowness of the petals is also quite remarkable, some of them 



appearing almost oblanceolate. . / 



Megarrhiza Gilensis.— Leaves deep green on both sides, not at ^ 



all glaucous, somewhat scabrous above, smooth beneath, orbicular- 

 cordate, the sinus mostly closed, 5-7-lobed almost to the base, the 

 divisions not broader above, entire, or with a single pair of large 

 teeth a little above the middle, each lobe and tooth tapering to an 

 acute, or a slender point; fertile flowers with rudiments of stamens; 

 fruiting pedicels slender, an inch or two long; fruit an inch in diam- 

 eter, globose, with a rounded base and shar])ly beaked or pointed 

 apex, clothed usuallv verv densely with soft spines, some of which
