Dear Doctor

When you visit Princeton
first (if the cruciferae are there)
wil you help me out of a 
difficulty about Streptanthus.

The enclosed figure is from a
plant of Texas, Lindheimers _

I thought it likely to be S.
musifolius. but in Hooker's
figure theere are no leafy
[underlined: bracts].  _ here they are persistent

See if your spce. are [?]
and whether this is not the case with 
S. Maculatus. Which is [mine?]
What's the difference between
them.

The fruit here figured is a
pod you sent me. (S. obtusifol?)
Pray help me about them.

As to Clematis, in order
to name the sp. I have
figured, I am obliged
