LEPIDIUM HETEROPHYLLUM Benruam. 
By Frepericxk Townsenp, M.A., F.L.S. 
Aw examination of specimens, in the Herbaria of Kew and the 
British Museuin., of the genus Lepidium, and especially of L. pepkt 
phyllum Benth., L. Smithit Hook., and of the var. alatostyla, led m 
to enquire how the dehiscence of the silicules of the latter is effected. 
None of the specimens were sufficiently advanced to show this 
satisfactorily, so at the commencement of the month of September 
in the present year I visited the original station at Redbridge, a 
Sgeieaa dette where I found the plant so far advanced that 
decay had already commenced ; but not one out of the 550 a Pe Fs 
I examined had dehisced, though they were ripe and pera? 
formed, and contained perfect seeds. The question arises—Is 
indehiscent character constant? I can hardly imagine it to 
otherwise, though it might be cocoa _ assert it Grainy
