 Bot. 6. p. 212. Between Rabbit's Ear and McNees Creeks; August. — Probably quite 

 distinct from the European O. campestris.

157. Phaca Fendleri (sp. nov.) : parce striguloso-puberula ; caule gracili flexuoso 

 angulato ; foliolis 7 — 1 1-jugis oblongo-linearibus obtusis glabratis petiolulatis (£- 1 unc. 

 longis); stipulis triangulatis parvulis ; racemis longe pedunculatis patentibus spiciformibus 

 10-20-floris laxis folium superantibus ; floribus purpureis patulis ; calycibus nigro-pubes- 

 centibus; leguminibus deflexis oblongis rcctis turgidis fere glabris estipitatis. — Wood- 

 lands, in the mountains, between Santa Fe and Pecos; August, 1847. — Plant a foot 

 high. Peduncles 5 or 6 inches long; half the length occupied by the flowers when 

 developed : these are one third of an inch long, apparently violet-purple, on very short 

 pedicels, and subtended by minute bracts. Calyx campanulate, with short triangular- 

 subulate teeth, pubescent with minute dark hairs. Legume (immature) three fourths of 

 an inch long, two lines broad, very minutely puberulent with white hairs, multiovulate, 

 several-seeded. — Evidently allied to P. flexuosa, Hook., and P. elongata, Hook., perhaps 

 too near to the former : but the flowers are larger, the calyx minutely black-haired and 

 not sericeous, the legumes apparently membranaceous, and the whole plant almost 

 glabrous. 



f 158. Apparently a mere variety of the next, with broader and more retuse leaflets. 

 s 159. P. gracilenta (sp. nov.) : perennis, canescenti-pubescens, humilis ; caule 

 erecto flexuoso superne ramoso ; stipulis subulatis ; foliis breviter petiolatis ; foliolis 7-9- 

 jugis cuneato-linearibus obtusissimis retusisve supra glabratis; pedunculo 10-20-floro 

 folium jequante vel superante ; calyce nigro-pubescente, dentibus subulatis brevibus ; 

 leguminibus chartaceis oblongis infiatis rectiusculis utrinque obtusis estipitatis cinereo- 

 puberulis. — Bare, rocky hills, Santa Fe ; April to June. — The specimen I possess is in 

 fruit only, about 8 inches high, with a slender, flexuous stem. The flowers are said to 

 be " pale purple." The legumes are three fourths of an inch long, terete, straight or 

 slightly incurved, and one fifth of an inch in diameter. In habit and foliage it is much 

 like Phaca annua of Geyer, and P. triflora, DC. (which Dr. Gregg has sent from Chi- 

 huahua, &c.) ; but the peduncles are larger, and the pods smaller, more chartaceous, and 

 much less inflated. 



160. P. macrocarpa (sp. nov.) : cinereo-puberula ; caule crasso fistuloso ramoso 

 striato-angulato adscendente ; stipulis triangulari-lanceolatis distinctis ; foliis rigidiusculis 

 1 — 5-foliolatis vel summis non folioliferis, rachi filiformi complanata, foliolis filiformi-linea-
