Genus XL. — Psilotum. Swartz. 
Capsule three-lobed, three-celled. 
This genus consists of two species of curious rigid dichotomous 
almost leafless plants, having no resemblance to the Lycopodiums, 
but connected by the uniform spores and spore cases. Capsule 
three-celled, each cell splitting down its centre to discharge the 
oblong spores from which the prothalia are produced.

inches long, almost leafless, very much twisted throughout, 
dichotomously forked repeatedly, the ultimate branches one to 
four inches long. The leaves are few and rigid, ovate, pointed, 
set on the angles of the stem, and bearing the capsules in their 
axils.
