Hab. Texas and New Mexico.—This quite agrees with C. mÿriophylla in habit and
texture, differing only in its wide - creeping rhizome and stipes without woolly
tomentum.

rachis and both surfaces densely coated with lanceolate-acuminate scales, which
are about 2 lin. 1., J lin. hr., bright-brown in the centre, silvery-wliite towards
the ciliated aud villous margin ; edge of the segments much incurved.—H k . Sp.

cover thickly the midrib of tlie pinuæ b en e a th ; texture coriaceous -.upper surface
densely clothed with white woolly tomentum, lower also densely matted, the
margin of the segments incurved.—C. tomentosa, H k . S p . 2. p . 96. {in p a rt), t.
109. A. non Link.
Hab. Gathered in an expedition from Western Texas to El Paso, New Mexico, October
1849, G. Wright, No. 816.—This differs from G. tomentosa by being coated with distinct
scales instead of mere woolly hairs on the stipe, rachis, and midrib of tbe pinnæ beneath,
and by being matted with tomentum on the upper surface. Gordon’s Colorado plant is
perhaps the same, but is more slender and less distinctly scaly. We are indebted to
Prof. Eaton for the elucidation of the United States species of the genus.
