My dear Dr. Schleohter: A long time ago I sent to you a few 
specimens and some photographs in the hope that you would 
give me your opinion of them, The specimens were Stelie spp. 
and the photographs represented among other things your JSpi- 
dendrura polyohlamys and Hexadesmia miorantha Lindl, To-day 
X am sending to you a few more photographs for you to pass 
on as they are ohiefly Lehmann numbers from Colombia and 
Tonduz speoimens from Costa Rioa. 
It seems to me that you have drawn the lines pretty 
the tracing of M* carpinterae Schltr. that you sent to me does 
not mathch the type specimen in the Unite d States Hatl. Herb.? 
M. microtoldes seems very close to M* gracilis.What is the 
critical difference between these closely allied species? 
I have received from Mr. Powell a specimen of Lockhartia 
mirabilis Reichb. f. said to have been determined by you. The 
details of the flower are not in accord with the plat© in Xen. 
Oroh, and I wonder if you have analyses of authentic material 
that you could send to me. 
By the time this letter reaches you I hope you will have 
been to Vienna and that aside from a valuaijl® set of traoinigs 
you will have good news for wm with regard to exchanges.
