VI. PLANTS WRIGHTIAN.E. 13 



Erysimum asperum, DC. Pebbly bed of the San Pedro, I.impio, and Mimbres. 



Greggia camporum, Gray, PL Wright, p. 9. ^ 1. Valley of the llio Grande, be- 

 low El Paso; June. Also in March, in flower. (l:U(3.) — The large flowers are 

 seldom white ; but usually rose-color, changing with age to purple. 



Draba micrantha, Nutt. in Torr. Sf Gray, Fl. 1.;;. 109; Gray, PL Fendl. p. 10. 

 Stony hills, near El. Paso ; March. (1317.) — The naked flowering stems are hairy 

 to the top ; and the petals are minute or wanting. 



Vesicaria angustifolia, Nutt. ill Torr. Sf Gray, FL 1. p. 101 ; Gray, PL 

 Lindh. 2. p. 145. On the Rio Frio and Leona, Western Texas; May; — a slender 

 form. (834.) Also in valleys near the Rio Grande, about 60 miles below El Paso ; 

 March; — a form with larger flowers and pods, the latter somewhat stipitate. 

 (1318.) Except in the more cinereous pubescence and the want of a consid- 

 erable stipe to the silicle, I cannot distinguish this from V. gracilis, Hook. 



V. RECURVATA, Engeliii. ; Gray, L c. p. 147. Stony prairies from Chicon Creek 

 to Piedra Pinta Creek, Western Texas ; May. (849.) — To this belong the speci- 

 mens of Berlandier referred by Hooker to his V. gracilis ; but Drummond's plant 

 (No. 13 of the third collection), from whose seeds was raised the plant figured un- 

 der this name, is the true V. gracilis. — V. lasiocarpa, Hook. I have seen only in 

 the Hookerian herbarium. The subjoined character was taken from the specimen.* 



V. STENOPHTLLA, Gray, PL Lindh. 2. p. 149: var. /3. procera ; foliis omnibus la- 

 tioribus lineari-spathulatis vel lanceolatis. — High rocky (limestone) prairies, Turkey 

 Creek, Texas, and westwai-d ; May. (8.50.) 



V. STENOPHTLLA, var. J. siUculis ovatis ! Gravelly banks of the Sabinal, Texas ; 

 May. (851.) — The silicles are from 3 to 4i lines long, ovate; the septum ellip- 

 tical ! 



V. STENOPHTLLA, var. B. humilis ; foliis inferioribus spathulatis nunc parce denta- 

 tis ; calyce pi. m. persistente ! — Prairies at the head of the Limpio ; also on the 

 Pecos, «&c. ; June, (852.) — The condensed and broad-leaved specimens look very 

 difierent from the ordinary state of V. stenophylla, into Avhich, however, the living 

 plants raised from their seeds evidently pass. The calyx is often persistent until 

 the pod is nearly full grown. 



V. STENOPHTLLA, var. e. diffusa ; foliis oblanceolatis et lineari-spathulatis pulchre 

 argenteis. — V. arctica. Gray, PL FendL p. 9. — Stony hills on the Rio Grande, 

 near El Paso ; March. (1319.) — An early state of the species, between 850 and 

 852; and mth an apparently annual root. To this (and not to the less silvery V. 

 argyrsea) belongs Fendler's No. 39, which is likewise an early state of this poly- 

 morphous species. 



* Vesicaria lasiocahpa {Hook. hied, vide Bol. Mag. suh /. 3464) : annua vcl biennis; foliis tcnuiter 

 pubescentibus baud canescentibus oblongis pinnatifido-laciniatis ; racemo iaxo ; iloribus inferioribus sa;pe 

 axillaribus; pedicellis folium adsequantibus gracilibus (12-15 lin. longis), fructiferis apice recurvo-nutan- 

 tibus ; silicula immatura estipitata globosa stylo sublongiorc (cum ovario) dense hirsuto-pilosa. — Between 

 Bexar and Trinity River, May, 1828, Berlandier (in herb. Hook.). — Habit and foliage much that of V. 

 grandiflora, but greener ; the inflorescence nearly as in V. argyraa. Remarkable for its hirsute-hairy 

 fruit.
