evidently the same pknt. ,

Hab. West Indies and Mexico to Brazil, Peru, and Juan Fernandez ; Sandwich Isles,
Madagascar, Mauritius, Guinea Coast.—X. extensa, Fée, is a narrow elongated form ;
X. Jamesoni, Hk. 2nd Cent. t. 14, a form with a distinct uncut upper part, the lower
two-thirds pectinato-pinnate, and the texture so rigid that the threadlilce inidrib remains
after the pinnæ fall ; Gi'ammitis myosuroides, Schk. {P. setosum, Mett. Hk. Sp. 4. p. 175),
is apparently a form of this pinnatifid throughout ; and P. ? binerve, ilk . Sp. 4. t. 273. B.
