377. Cercis occidentals (Torr. ined.) : frutex ; foliis 

 subreniformibus obtusissimis ; leguminibus oblongis obtusissi- 

 mis breviter apiculatis vix stipitatis. — C. Siliquastrum, var. 

 Benth. PI. Hartw. No. 1706, p. 307. — Var. floribus etiam 

 paulo minoribus, foliis supra nitidioribus. C. reniformis, En- 

 gelm. Mss. Rocky plains of the Upper Guadaloupe. March, 

 in flower ; June, with ripe fruit. A shrub, forming thickets, 

 never becoming a tree. — This is entirely distinct from C. 

 Canadensis ; but does not differ from the Californian plant of 

 Fremont and of Hartweg, except that the flowers are a little 

 smaller still, being no larger than those of C. Canadensis, 

 and the full-grown leaves are rather thicker and more shining 

 above. The Texan and the Californian plants agree in their 

 short and scarcely stipitate pods (only 2 or 2| inches long, 

 and two thirds of an inch broad,) which character, with the 

 size of the flowers, would seem abundantly to distinguish it 

 from C. Siliquastrum, the legumes of which, including the 

 manifest stipe, are six, or at least five inches in length. (Dr. 



Charles Wright. — The plants from seeds sown in the spring blossom from midsum- 

 mer to autumn. Stem a span high, seldom branched. Leaflets 4 lines long, the 

 upper surface sparsely, the lower densely beset, like the stem, &c, with villous- 

 hirsute loosely appressed hairs. Peduncles in fruit 2 or 3 inches long. Legumes 

 half an inch long, densely hirsute, straight, rather acute, tipped with the short style, 

 often carrying away the inconspicuous corolla upon its apex as it enlarges, nearly 

 erect, only three or four produced in each capitulum, scarcely twice the length of the 

 persistent subsessile calyx. Bracts subulate, the lower resembling the calyx-lobes. — 

 Mr. Wright has also detected Oxytropis Lamberti, Pursh, in "Western Texas ; and 

 likewise a unifoliolate Desmodium, namely: — 



Desmodium Wrightii (sp.nov.): caulibus gracilibus ramosis puberulis; foliis 

 unifoliolatis breviter petiolatis ; foliolo membranaceo oblongi-ovato obtuso basi subcor- 

 dato fere glabro ; stipulis stipellisque subulatis minimis ; racemis laxis ; tomento 

 3 - 4-articulato breviter stipitato, articulis insequilateris ovalibus. — Austin, Texas, 

 Mr. Charles Wright. — Stems one or two feet high. Leaves veiny, paler and 

 minutely pubescent underneath, mucronulate ; the lower two inches long, on petioles 

 half an inch long ; the upper successively narrower and smaller, on shorter petioles. 

 Legume less than an inch long ; the stipe as long as the stamineal tube.
