Botanical Notes. 
We have received the following circular from J. Donnell 
Smith, which is worthy of interest, especially as the collection 
will be named at Berlin by most eminent authorities. 
Baron Eggers has been engaged by the undersigned, and 
under the patronage of the Royal Academy of Sciences of Berlin, 
to undertake a joufney of botanical research in the higher moun- 
_ tain regions of San Domingo that have not yet been explored. 
The plants to be collected will be distributed in two series with 
corresponding numbers. The first series will embrace such plants 
as have not already been distributed in Eggers’ Flora Indie Oc- 
ctdentalis Exsicc., and will cost forty (40) marks per hundred. 
The second and larger series will omit only the ubiquitous 
tropical species, especially those of the sea-coast, and will cost 
thirty (30) marks per hundred. The determinations will be 
elaborated by the undersigned, assisted by various monograchers. 
He will be pleased to receive subscriptions to either series, but 
_ without prepayment. In view of the difficulties of transportation 
on the Island, only a limited number of sets will be collected, and 
a prompt notification is requested from those who wish to sub- 
scribe. Dr. IGN. URBAN.
