PLANTA FENDLERIAN2. 37 
ribus remotis; pedunculis folio longioribus ; racemis multifloris; floribus decurvis majusculis 
(ochroleucis seu albidis) ; leguminibus elongatis lanceolatis membranaceis glabris turgidis 
rectis utrinque acutatis in stipitem calyce cylindraceo longiorem attenuatis polyspermis. — 
Rocky declivities, near Santa Fe ; June. — Root apparently perennial. Plant one or two 
feet high, much branched, cinereous with a very minute appressed pubescence. In ap- 
pearance the foliage is intermediate between that of P. pectinata and P. podecarpa ;_ but 
the leaflets are much fewer than in either; more frequently only two or three, scattered 
along the flattened rachis. They are distinctly articulated, from half to three fourths of 
an inch long and about half a line wide. Flowers nearly as in P. pectinata, but the calyx 
is not dark-haired. The pods (which are not quite mature) are two inches long, includ- 
ing the stipe, apparently terete, and two lines in diameter, of a thin membranaceous tex- 
ture, with neither suture introflexed, about 20-seeded. 
161. P. picra (sp. nov.): annua, humilis, undique strigoso-incana ; caulibus ramo- «' 
sis diffusis ; stipulis triangulari-subulatis majusculis ; foliolis 4—7-jugis anguste linearibus 
obtusis ; racemis folio subbrevioribus 7-15-floris; dentibus calycis setaceis tubo vix 
brevioribus (corolla rosea vel albida, carina sepius purpureo tincta) ; leguminibus ovalibus 
obtusis rectis membranaceis inflatis glabris purpureo-pictis_breviter stipitatis oligospermis. 
— Loose, sandy soil on the banks of the Rio del Norte, especially among low shrubs; 
April (in flower) and June (in fruit). — Allied to P. longifolia, P. annua, Geyer, P. Hook- 
erlana, &c., and with the same beautifully mottled legumes. The appressed hairs, which 
render the plant quite hoary throughout, are attached by a point below their middle. 
Stems 5 to 9 inches high, often branched from a straggling or creeping base, which has 
apparently been covered with loose sand. Leaflets one half to three fourths of an inch 
long, sometimes almost filiform. Flowers spreading, one fourth of an inch long, the 
young fruit pendulous. Pods three fourths of an inch long, very obtuse, straight, on a 
stipe about the length of the calyx. The flowers are twice as large as those of P. graci- 
lenta, no. 159; which are pubescent and not stipitate nor mottled.

May to June, in flower; June to Aug., in fruit. — A foot high, a silvery white species ; 
more so than in the original specimens of L. decumbens, which, imperfect as they are, I
