es that of the stipes. The whole plant is more slender, its 
frond far narrower, and much more acuminated than that of 
O. vulgatum. The reticulation of the leaf, which is chiefly 
apparent in the dried specimen, exists equally in both species. 
The figure of Rumpuivs, in the Herbarium Amboinense 
(v. 6. t. 68. f. 2.) which is cited by WILLDENOW, as a syno- 
nym to his O. ovatum, seems scarcely different from O. vulga- 
tum, the shape of its frond being almost precisely similar.
