22 PLANTS WRIGHTIAN^. V. 



laribus, infimis solitariis, cseteris fasciculatis, superioribus spicato-racemosis ; pedun- 

 culis unifloris brevissimis ; capsula ovoidea lobis calycis ovato-triangulatis paulo lon- 

 giore, coccis 15 mucronatis dispermis. — Sphseralcea miniata, Gray, PI. Fendl. p. 19, 

 8f Gen. III. 2. t. 127, non Malva miniata, Cav. — Sides of mountains near EI Paso; 

 Sept. " Much, branched and spreading from the root." — I had doubtfully referred 

 this species to the Malva miniata, Cav. ; but that has probably been correctly iden- 

 tified by Hooker and Arnott [Bot. Misc. 3. p. 151) with specimens from Mendoza, 

 gathered by the late Dr. Gillies. At least, one of these specimens accords admira- 

 bly with the figure of Cavanilles, which our plant does not. Wright's specimens 

 are more dwarf, diffuse, and pubescent than those of Fendler, doubtless from having 

 been gathered at a drier season or locality. 



61. Pavonia Wrightii, Gray, Gen. Bl. 2. p. 76. t. 130, ^ PI. Lindh. 2. p. 161. 

 Rocky cliff's of the Nueces River, and hills of the Rio Frio, Texas. — A pretty 

 plant in cultivation, producing an abundance of its fresh rose-colored flowers dur- 

 ing the whole season. 



62. Malvayiscus Drummondii, Torr. 8c Gray, Fl. 1. p. 230 ; Gray, Gen. Bl. 2. 

 t. 131. Bottoms of the Leona River, W; Texas.* 



63. Hibiscus cardiophyllus (sp. nov.) : humilis, tomentosus ; caule e radice pe- 

 renni erecto ; foliis cordatis subrotundis crenulato-dentatis obtusis vel acutiusculis 

 supra velutinis subtus densissime cano-tomentosis ; stipulis setaceis ; pedunculis 

 axillaribus solitariis unifloris folium sequantibus vel superantibus paulo sub apice 

 articulatis ; involucello 9- 10-phyllo; phyllis spathulato-lanceolatis tomentosis laci- 

 niis calycis lato-lanceolatis 3-5-nerviis sequilongis vel demum brevioribus; corolla 

 roseo-purpuvea columnam stamineum superante; capsula glabella calyce breviore, 

 valvis chartaceis ; seminibus puberulis in loculis paucis. — Rocky hill-sides, Turkey 

 Creek, W. Texas, June ; and on the Rio Grande, in Southern Texas. Also Zimapan, 

 Mexico, Coulter (No. 805). Near Monterey, GreffCf (185, &c.). Dr. Edwards (^ 

 Major Eaton, Wislizenus (370). — Mr. Wright's specimens are mostly in fruit; the 

 others are finely in flower. The stems are rather stout, from 9 to 20 inches high, 

 from a lignescent perennial root ; the exactly cordate leaves are from one and a half 

 to above two inches in diameter. Peduncles 3 or 4 inches long. Leaves of the in- 

 volucre broad and conspicuous. Petals more than an inch long, spreading, deep 

 rose-purple, considerably longer than the column. Ovules 10 or 12 in each cell. 

 — I know of no species with which this may be particularly compared. 



64. H. (Bombicella) denudatus, Benth. Bot. Voy. Sulph. p. 7. t. 3. /3. involu- 

 CELLATus : ramis superne minus foliosis ; corolla majore ; involucello e bracteolis 

 5-7 modice evolutis setaceis. — Sides of hills near El Paso, New Mexico ; Sept. 

 Gathered in the same region by Wislizenus, and at Cerros Bravos, Northern Mexico, 

 by Gregg (481). — Stems suffruticose, one or two feet high, much branched ; the 

 flowering branches more naked than in the poor specimens gathered in the voyage 



* Malvaviscus Floridanus, iVw/Z., is Hibiscus (Cremontia) Floridanus, Shuftleworfh, Coll. Rugel (Key 

 West) No. 104, and also, I believe, H. triincatus, A. Rich. Fl. Cub. 1. p. 144. t. 16, as well as H. Ban- 

 croftianus, McFad. Fl. Jamaic. 1. p. 70 (H. Mackleyanus, Bancroft.).
