1. E. Nyctelea L. E. ambi'ffua 'Nutt, forma tenella. — Eastern 

 N. America. 



2. E. MEMBRANACEA Bentli. — California. Corolla with one lobe 

 external in lestivation. Ovary not wholly "glabrous." The ape:s 

 bears a few very stout bristles. 



§ 2. EUCRYPTA. Placentas utrinque ovuliferte, heterospermas, 

 nempe facie ventrali biovulata, dorsali 1-2-ovulata monosperma : 

 semina ovalia ; normalia rugoso-tuberculata, teretia ; posticum menis- 

 coideum lajve inter valvam et placentam persistentem absconditum ! 

 Folia 2-3-piunatipartita : flores quasi-racemosi. — Eacrypta Nutt. 

 PI. Gamb. p. 159. 



3. E. ciiRYSANTHEMiFOLiA Benth. Eucrypta paniculata & E. 

 foliosa Nutt. I.e. Phacelia micrantha'^ var. -pinnatijida Torr. in 

 Ives, Colorad. Exp. Bot. p. 21. — California. 



4. DRAPERIA Torr. 



1. D. SYSTYLA Torr. in Gray Proc. Am. Acad. 7, p. 401. Nama 

 systyla Gray, I.e. 6, y>- 37. — I have nothing of importance to ndd to 

 what is known of this interesting Califoruian plant, except that the 

 dehiscence is somewhat peculiar. The thin dissepiment is complete ; 

 the semisepta meeting in the centre, but without any placental enlarge- 

 ment ; the ovules, two in each cell, are pendulous from near its sum- 

 mit : in dehiscence a thin central portion, or placenta, usually separates 

 neatly from the semisepta and remains between the four seeds, falling 

 with them, so that when the capsule is closed again a central foramen 

 is leit. 



5. PHACELIA Juss. 



This comprehensive genus is certainly polymorphous, but no more so 

 than Eutoca R. Br. would be, if the two genera were retained as pro- 

 posed by Brown. Most of the true quadriovulate Phacelias are nearly 

 represented by species of Eutoca, — as P. circinata, Brewer i, humilis, 

 and hrachijantlia by P. {Eutoca) ciro'natiformis, divaricata, and curvipes, 

 and P. malco'foUa by P. {Eutoca) Bolanderi and loascefolia ; while the 

 set of which P. tanacetifoUa and congesta are the type is imitated in foli- 

 age and inflorescence by P. infundihuliformis ; and P. hipinnatijida and 

 the section Cosmanihus are related to P. {Cosmanthoides) parvijiora^ 

 glabra, patulijlora, &c. Indeed Brown's Eutoca parvijlora and the 

 closely allied species, generally with 3-4-ovulate placentae, occasionally 

 show a reduction to a single pair. It is still less practicable to keep
