'The same organization prevails in the female flowers as in 
Gnetum : Mr. Brown originally affirmed the instances of 
truly naked ovula. 
This genus is a remarkable one, and has marked analogies 
in certain important points with Equisetum and Casuarina? 
With the former its cuticle seems to perform the principal 
aérating functions, and it abounds in silex, the particles of 
which appear to have no definite arrangement, but occupy 
the disks of the stomata! 
At least such is the supposition, I have for the present 
formed, it is easily proved by examining the surface at early 
periods, and the very young leaves, otherwise 1 can in the 
mature ramuli find no stomata.* 5. 
* I find that in Ephedra Asparagina Itinerary Hym 340, no. 67, 
thereis no deposition of silex in the cuticle, which has stomata, arranged 
as the disces of the silicous species, pes along. the spaces be- 
tween the bundles of elongated fibre 
So far my supposition is borne iid: 
This species approximates, to Conifere having generally whorled 
acerose leaves on its young branches.
