10 PLANTS WRIGHTIANjE. VI. 



FUMARIACE^. 



CoRYDALis AUREA, Willd. var. siliquis breviusculis leviter curvatis adscendentibus. 



— Sandy hills along the Rio Grande, near El Paso; Feb., March. (1309.) — 

 This is intermediate between the ordinary form of the species and No. 433 of Lind- 

 heiraer's collection in 1850, named C. curvisiliqua, n. sp. by Engelmann. That has 

 still longer pods (an inch and a half long), on shorter pedicels. 



PAPAVERACE^. 



EscHSCHOLTZiA DouGLASii, Hook. (§' Am. Bot. Beech. ]). 320 ; Torr. Sf Gray, Fl. 

 \. p. 664; var. parvula. Among rocks, on mountains near El Paso, where it was 

 first detected by Dr. Bigelaw ; April. (1310.) — Also on the Santa Maria, near 

 Lake Gusman. — This is the first time that an Eschscholtzia has been found east of 

 the Pacific border of Oregon and California. It appears to be only a rather depau- 

 perate form of the Oregon species. The petals are three fourths of an inch in length. 



CRUCIFEE^. 



Nasturtium palustre, DC. Old bed of the Rio Grande, .50 miles below El Pa- 

 so, June, and Cimieluque Spring, April. (843.) — These specimens have pods as 

 long as those of the European plant. In most North American specimens they 

 are much shorter. (Vide PI. Fendl. p. 6.) 



N. OBTUSUM, Nutt. in Torr. Sf Gray, Fl. ; Gray, PI. Fendl. p. 6. With the pre- 

 ceding. 



TuRRiTis PATULA, Graham; Gray, PI. Fendl. p. 7. Mountains near Coppermine 

 Creek, Nefw Mexico. Also, in fruit, near Lake Santa Maria, Chihuahua. (1313). 



— To this belongs the Streptanthus virgatus, Nutt. in Torr. Sf Gray, Fl. The ripe 

 seeds occupy a single row ; and the genus is not distinguishable from Arabis. 



Streptanthus longifolius, Benth. PI. Ilartw. p. 10 ; Gray, PL Fendl. p. 6. 

 Mountains and stony hills near the copper mines ; Aug. (in flower). (844.) — The 

 leaves are only from 1} to 2 or 3 inches in length; the radical and lower cauline 

 ones spatulate. 



S. LiNEARiFOLius, Gray, PI. Fendl. p. 7, Sc PI. Wright, p. 7. Valley of the Limpia, 

 and pebbly beds of streams, from the Mimbres to the copper mines ; also at Lake 

 Santa Maria, Chihuahua. — Root often thickened and ligneous, certainly perennial. 



S. PLATYCARPus (sp. iiov.) : glabcrrimus, glaucescens ; foliis caulinis cordato- 

 oblongis amplexicaulibus sinu clause integerrimis repandisve, infimis obovato- 

 oblongis sfcpe lyrato-pinnatifidis petiolatis ; siliquis oblongo-linearibus planis erectis. 



— Valley of the Pecos, on stony hills ; June. (844 bis.) — Root annual. Stem rather 

 stout, branched from the base, 1 to 2 feet high. Radical leaves 6 or 8 inches long, 

 thickish, lyrately pinnatifid; the lower cauline similar, or obovate and entire or 

 nearly so ; the upper cauline and rameal leaves from 3 to H inches long, usually 

 quite entire, obtuse, or the upper acute, strongly cordate-clasping, with the rounded 

 posterior lobes approximate or overlapping. Racemes loose, paniculate. Bracts 

 none, or sometimes a minute one at the base of some of the pedicels, or with a foli-
