ZYGOPHYLLACE^. 



Kallstrcemia grandiflora, Torr. in Pl Wright. p. 28. Near Ojo de Gavilan, 

 bcyond thc copper mines, New Mexico ; Aug. (911.) — The same as Coulter's and 

 Emory's specimens. Leaflets oftcn 6 pairs. Flowers very large and showy. 



K. MAXiMA, Torr. 8r Grai/, — a depauperate variety. East of the Eio Grande, 



Ncw Mexico ; June. (912.) 



Larrea Mexicana, Moricand ; Gra^, Pl Wright. p, 28. Bottoms of the San 



Pedro, "Western Texas ; May. (913.) 



RUTACE^. 



KosBERLiNiA spiNosA, Zucc. ; Grag, Pl. Wright p. 30. East of the Rio Grande, 



r 



New Mexico; June, in flower. (914.) 



RuTOSMA Texanum, G7'a^, Gen. III. t 155, ^ Pl. Wright l. c. Stony prairies of 

 the Sabinal, and near Comanche Spring, Western Texas ; May, June. (915.) 



r 



CoroUa duU yellow. 



"R. Texanum, var. corolla purpurea ! Hills near El Paso ; April. Mountains 

 near Santa Cruz, Sonora ; Sept. (915^) — AIl the specimens from about EI Paso 

 and westward are said to have purple flowers, and they are purplish in the dried 

 specimcns. They are yellow in Gregg's specimens from Monterey. 



COCHLOSPERME^. 



Amoreuxia Schiedeana, (Planch. in HooJc. Lond. Jour. Bot 6. p. 140. t 1 ; non 

 Gray, Pl. Wright.) : foliis 7 - 9-partitis, segmentis spathulatis ; fructu ovoideo-glo- 

 boso pollicari ; serainibus reniformi-curvatis, tegumento externo tenui hispidulo 

 interiori conformi; embrj^one homotrope incurvo. (Tab. XH. A.) — Euryanthe 



t 



Schiedeana, C^a?w. q^ Schlecht itt Linncsa, 5. p. 225. Amoreuxia palmatifida, i)(7. 

 Prodr. 2.p. 638 ? (Mexico, Schiede. Coulter ! (Sonora Alta). New Granada, Purdie !) 

 Hills along mountain streams, near Deserted Rancho, in the northern part of So- 

 nora; Sept. (916.) — The specimens are chiefly with ripe fruit; the pods ovoid- 

 globose, barely an inch long, and therefore only half, or less than half, the size of 

 those of Mr. Wrighfs former specimcns (No. 79), figured in PL Wright t 3, B. 

 A more remarkable difi^erence is found in the seeds, which in the present specimens 

 are strongly incurved-reniform, with the fragile exterior integument conformed to 

 the inner one, and beset with minute hispid hairs ; and the embryo is simply curved, 

 without any double flexure. The lobes of the leaves, also, are more numerous and 

 narrower. I cannot doubt that these specimens belong to the species characterized 

 by Chamisso and Schlechtendal (who describe the pod as scarcely an inch long and 

 ovoid-globose, the seeds as reniforml and the leaves as 5-9-parted). It is cer- 

 tainly the plant recently figured by Planchon.
