2-3 inches long, petiolate, pinuately divided into 3-5 ovate- 

 oblong, crenate or incised lobes, the terminal much the 

 largest: racemes open, elongate, often dichotomous; pedi- 

 cels filiform, villous 3-5 mm. long, deflexed in fruit: calyx 

 villous, 2-3 mm. long, the broadly-obovate lobes cleft to 

 the base, becoming conspicuously enlarged and thin-sca- 

 rious in fruit : corolla bright blue with white throat, twice as 

 long as the calyx, the rotate limb as long as the throat; ap- 

 pendages uniting below over the filaments, which are mod- 

 erately exserted: style cleft one-third its length, the lower 

 third and the ovary pubescent; capsule globular, less than 

 half as long as the fruiting calyx: seeds dull, minutely 

 favose-reticulated, the margins and the central ridge cor- 

 rugate. — Magdalena Island. 



Phacelia affinis Gray. — El Rancho Viejo. 



Phacelia micrantha Torr. — Paraiso, El Eancho Yiejo. 



In most of these specimens, there is to be found no trace 

 of transverse folds in the throat. They are, however, other- 

 wise undistinguishable from forms collected in Arizona, and 

 share with them a peculiarity which appears not to have 

 been noticed, and which approaches the species somewhat 

 to § Eucrypta of Ellisia, the capsule being lined with a pair 

 of thin conformed placentae, each of which, in addition to 

 the numerous grub-like seeds borne on the face, has an ad- 

 ditional similar one behind it. 



Nama demissum Gray. — San Gregorio. 



Nama hispidum Gray var. — San Gregorio. 



Nama stenocarpum Gray. — Comondu. In the solitary ex- 

 ample collected of this rather homely but interesting plant, 

 the filaments are bordered in their lower third by linear 

 appendages which terminate as tooth -like processes above, 

 the 3 or 4 styles are united half their length, and the cap- 

 sule has as many placentae as there are styles. The range 

 of the species has been recently extended northward by
