echinospora. Botanical collectors do not seem to have taken, nor do 
now. take, much interest in the genus. Let. us hope that these hastily- 
written remarks may stir them up to greater activity. M. Gay is 
doing his utmost to learn the distribution of the plant in Frauce, Dr. 
A. Braun is doing the same in Germany, and surely English botanists 
should not be lagzards in the chase. Allow me to constitute myself a 
centre of communication on matters relating to Zsoéfes, and. to. request 
all persons interested in the plants to write to me at Cambrid 
In conclusion, it may be well to add, that J. echinospora was first

in the ‘Bulletin de la Société Botanique de France’ (viii, 164, March 
22, 1861), and that the first ecord of its discovery in Britain is, L
