26 PLANTS WRIGHTIAN,E. TI. 



ZYGOPHYLLACE^. 



Kallstroemia grandiflora, Torr. in PI. Wright, p. 28. Near Ojo de Gavilan, 

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

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



K. MAXIMA, Torr. 8f Gray, — a depauperate variety. East of the Rio Grande, 

 New Mexico ; June. (912.) 



Larrea Mexicana, Moricand ; Gray, PI. Wright, p. 28. Bottoms of the San 

 Pedro, Western Texas ; May. (913.) 



E U T A C E ^ . 



KcEBERLiNiA spiNosA, Zucc. ; Gray, PL Wright, p. 30. East of the Rio Grande, 

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



RuTosMA Texanum, Gray, Gen. W. t. 155, 8f PI. Wright. I. c. Stony prairies of 

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

 Corolla dull yellow, 



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

 near Santa Cruz, Sonora ; Sept. (915".) — All the specimens from about El Paso 

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

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



COCHLOSPERMEiE. 



Amoreuxia Schiedeana, (Planch, in Hook. Lond. Jour. Bot. 6. j). 140. t. 1 ; non 

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

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

 interiori conformi ; embryone horaotrope incurvo. (Tab. XII. A.) — Euryanthe 

 Schiedeana, Cham. 8f Schlecht. in Linnaa, 5. p. 225. Amoreuxia palmatifida, DC. 

 Prodr. 2. p. 638 1 (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. AVright's former specimens (No. 79), figured in PI. Wright, t. 3, B. 

 A more remarkable difl'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 

 narrowei'. 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 reniform 1 and the leaves as 5 - 9-parted). It is cer- 

 tainly the plant recently figured by Planchon. 



A. Wrightii : foliis 5-partitis vel sub-7-partitis, segmentis obovatis basi cuneatis ; 

 fructu oblongo-ovoideo (scepius bipollicari) ; seminibus obovoideis baud incurvis, 

 tegumento externo laxo arilliformi glabro ; embi-yone biarcuato. — A. Scheideana, 

 Gray, PI. Wright, p. 29. t. 3. B., excl. syn. — Hills at Painted Caves, near the San
