and not so much narrowed at the points, the margins of the trigonous upper portion more pellucid, so as to 
give the idea of their having a narrow lamina, of which, however, on making a cross-section, there is no 
trace, and the limbation of the base is narrower; a few oblong septate brown bodies have been seen attached 
to the apices of the leaves, similar to those observable in Syrrhopodon and Calymperes. Tab. 98g. Fig. 1, 
plant of the natural size; 2, a leaf, with a portion near the base, more enlarged, a cross-section of the upper 
part and the point as seen laterally, all magnified. 4. O. asperum, Mitt. Linn, Soc. Journ. 1868, p. 178.—
