I
Lengtn of frond about two feet; above dark green, beneath
densely covered with a pale greenish yellow powder.
Sprengel remarks in his description of this F e rn , that it is
white-powdered beneath, b u t all the fronds which I have seen
have been yellow-powdered.
F o r fronds I am indebted to Mr. J . Smith, Curator of the
Royal Gardens, Kew, and to Mr. E . J . Gray, of St. Thomas’,
Exeter.
The illustration is from Mr. Smith’s frond.
