Leaves jelly-like, expanded in a circle, resembling a bat’s wing; sometimes 
destitute of saucers, and covered with numerous small tubercles : lobes 
very blunt. Saucers near the centre of the leaves. Lightf. Leaves broad, 
flat, between scolloped and lobed, in substance as well as colour much 
resembling a bat’s wing, sometimes covered, in the place of saucers, with 
granulations of the same colour as the leaf. Saucers very numerous, 
minute, at first appearing like tubercles, of the same colour with the 
leaves, with a slight hollow at the top ; afterwards expanding, and at 
length flat, border of the same colour with the leaves. The progress 
from tubercles to saucers shows that there exists no absolute distinction 
between them. Mr. Woodward.
