Grows in dense. tufts. Stems about 1 inch long, reclining, 
moderately broad, compressed, solid, smooth, divided into a few. 
horn-shaped branches, when fresh brown olive, when dry black- 
ish ; stiff, tough, horny, pellucid when moist. Tuberc/es termi- 
nating, plano-convex, circular or oblong, of different sizes, 
blackish brown, fleshy, fungous and white within. In some 
plants saucers are produced at the ends of the branches, flat or 
gently concave, border regular, of the same colour with the 
saucer, sometimes bearing horn-shaped branches. These sau. . 
cers being smaller than the tubercles, are probably changed into 
tubercles. Dir,
