          I have Bentham's [added: Hartweg's] [crossed out: No. 3] no. 1831
 & 1832, but I do not find 
 his 1830 (Muhlenbergii)


 I send you a radical & an
 upper branch of 1832, and a
 good radical branch of 1831.
 This will put you up to his two
 species.


 He does not seem to have my
 E. [Erythraea] Venusta. But it is a Mexican, I
 suppose.


 I suppose the species vary dreadfully.
 I whould want 4 or 5 days
 to study the genus in before I could
 say anything about it.


 No more to-day, from
 You affectionate
 A Gray
