ET. 28.] JOURNAL. 223 
Endlicher is to give a figure in “Iconographia Gen- 
erum Plantarum,” and the description has gone to 
the printer in one of Endlichev’s articles in the “ An- 
nals of the Vienna Museum,” — Ceelostylis Logani- 
oides, Torr. & Gr. Can’t we get more of it? Has 
Leavenworth found it? 
I have been looking over the “ Reliquize Henkeane,” 
and examining what specimens of the collection from 
North America they have in the Vienna Herbarium. 
Endlicher goes this week to Carlsbad to recruit his 
health, stopping a day at Prague. He has kindly 
taken a list of my desiderata of the species published 
in that work, and I hope to get some bits of them. 
have copied so much from the work that we can get 
along even if I do not see it again, but as I was about 
to purchase it, Endlicher suggested that he should see 
if Pres] himself has not a copy left for us. Follow- 
ing this hint I have sent by Endlicher a copy of the 
“Flora” to Presl,! in nomine auctorum. 
There is a new genus of Pres] in Loasez (Acrolasia) 
from Mexico, which may be Nuttall’s. The most curi- 
ous thing is a new genus of Datisceae from Monterey 
(why have none of the other collectors found it’), 
called Tricerastes ; very interesting. 
I find from all inquiries that it is very difficult to 
find Nees von Esenbeck? at Breslau, especially i in the 
summer. He is a queer stick altogether, is not well 
satisfied with his situation at Breslau, and spends the 
greater part of his time at a little place high up in the 
Riesengebirge, studying Hepatic.
