T h e above F e rn takes its name from the copious snowy-white
powder with which the u n d e r side of the frond is densely
covered. The p resent species and the Cheilanthes fa r in o sa of
Ho o k e r, {^Cassebeera fa r in o sa of Smith,) are undoubtedly the
handsomest of the silver F e rn s ; the fructification occurring only
along th e edge, the whole interior surface of the pinniB is
covered with white powder, the fructification being, as it were,
a dark narrow b elt surrounding the white surface. The effect
is greater th an in the silver F e rn s of the Gymnogrammas, from
the circumstance th a t in the la tte r family the seed-vessels are
scattered all over the frond.
