and the same species. I have a specimen in my possession, in 
which they both grow from one root, and one branch is divided 
with furcellatus on one part, “and fastigiatus on the other. F. 
fastigiatus 1 am inclined to think will be found to be the male, 
and furcellatus the female plant. Mr. Woopwarp. ‘The 
admirable figures of Mr. Stackhouse and Major Velley fully 
illustrate Mr, Woodward’s observation. If we may suppose 
that Gmelin and Lightfoot have been mistaken about the blunt 
ends of the branches pouring out a prolific mucus, then it will 
follow that these are shoots which have not yet put forth the 
strap-spear-shaped fructification : but if they are right, Mr. Wood- 
- Ward’s conjecture will be confirmed. “a .
