          If De Candolle is right in his character of the
genus, than it belongs to Thapsiae, & Pteryxia Nutt
is a perfectly distince genus. If you are right,
then the genus may hold together as in the Flora,
but I have a new one of two species. But
I cannot but think that you have not hit the
right interpretation of the fruit of [?] [?] 
3.

At the same time can you tell me
anything of Fendl. no. 276. which has no
fruit.

P. S. And Casey adds please send
all your Amer. [Peucedanum's?] too!
I think we have made out [?] this part =
doing species pretty well: but it would be well
to compare notes, & settle some Calif. specimens
I have.

"Culantro" Gregg. Monterey & Saltillo is
Coriandrum sativum.
