 larger than the figure on the plate 1 75. 



In its firfr ftage it is befet on the outiide with a kind of grains, 

 or little puftules, which are not feen without a glafs ; in time 

 thefe difappear, and the outride becomes dully with a white pow- 

 der, probably the feeds of the plant.

 of ochre colour; the fubilance of the plant very moiit and brittle.
