guidance of Herr Behnick. I examined the very rich collection 
of cacti, and a large number of South African plants, many of 
which I saw nowhere else. he collection of aroids is rich in 
unusual and rare forms. With the permission of Dr. Engler, I 
made out a list of desiderata, which, according to the rules of 
that institution, must be officially submitted to him by yourself. 
I also called upon Dr. Urban and handed to him the package 
of West Indian herbarium specimens upon which you desired 
his opinion. He took an active interest in the matter and gave 
them his immediate personal attention, expressing the wish that 
the two institutions might codperate in the work on the West 
Indian flora, and offered his services to that end. 
On the 24th I visited Halle, and called upon Dr. Mez, sub- 
mitting to him for determination several species of Lauraceae and 
Bromeliaceae. He gladly made these determinations. I found 
him just beginning the study of the grass genera Panicum and 
Paspalum for Engler’s Pflanzenreich. Most of the large col- 
lections in Europe had been sent him for study, so I was enabled, 
through his kindness and help, to see types of a number ot 
American species in these two difficult genera. He is quite 
anxious to secure herbarium specimens of grasses, and I arranged 
with him an exchange of these for specimens of Bromeliaceae, 
Lauraceae and Myrsinaceae, an extensive monograph by him of 
the latter family having just been published. I was surprised to 
find an interesting collection of succulents at the university 
garden, especially rich in the genus Afesembryanthemum, I 
made a list of such plants as we desired and as could be spared. 
These will be forwarded during the summer. 
My next visit was to Frankfurt-am-Main, on the 25th. The 
Palmengarten located here is, strictly speaking, not a botanic 
garden, but is more a pleasure park. It belongs to private 
parties, and an admission fee is charged, which contributes partly 
to its support. Showy horticultural plants prevail, little of 
strictly botanical interest finding place 
From Frankfurt a day’s run brought me to Paris on the 27th. 
At the Jardin des Plantes Prof. J. Constantin is in charge of the 
living collections. An exchange was arranged with him, and a
