Hab. Mexico: Orizaba, 9,000-10,000 feet, Ehrenberg, n. M^Z ; Xalapa and 

 Real del Monte, Coulter, n. 1708 and 1705: San Felipe, Andrieux, n. 36. — 

 Mettenius unfortunately makes no allusion to tbe affinity of tills species ; but 

 Martens and Galeotti candidly acknowledge its close affinity with P. vulyare, 

 " but the frond is pilose and segments subciitire." .My specimens from Coulter 

 and from Andrieux quite agree with the figure above referred to, and I had cer- 

 tainly only considered them a slightly pubescent form of P. vulyare. The speci- 

 mens, however, want the caudiform apex so common to that species. 



106. P. (Eupolypodium) chnoophorum, Kze. ; " caudex re- 

 pent clothed with reddish lanceolate acuminated scales, stipes 

 2 inches long, fronds everywhere especially at the costse 

 clothed with white hairs, 1 foot long lanceolate pinnatipartite 

 to the costa, segments H-li inch long 4-4^ lines wide ob- 

 long or elongato-oblong-lanceolate rather obtuse subfalcate 

 acuminate repando-sinuate or subcrenate, the base dilated 

 on both sides, the superior adscendenti-coadunate decreasing 

 at both extremities, lowermost subremote distinct a little de- 

 flexed." Metten.— Kze. Bot. Zeit. 1839. Beibl. 1. 34. Met-

Hab. Brazil, Blanchet. 



*** Fronds pinnatifid, or pinnate, or even Mpinnatifid, more or less furfuraceous, 

 with often peltate frinyed scales, of toMch P. incanum may he considered the 

 type. (Lepidotae.— 107-122.)* 



107. P. (Eupolypodium) incanum, Sw. ; " caudex creeping 

 clothed with ad pressed lanceolato-subulate rigid finely ciliated 

 or glabrous scales, stipes 1-4 inches long, fronds subcoriace- 

 ous 2-5 inches long ovato-oblong deeply pinnatifid on the 

 upper side sparingly clothed with ovate or rotundate denticu- 

 lated scales bristle-pointed eventually naked, on the under 

 side together vrith the stipes densely squamose with mem- 

 branaceous rotundate or ovate obtuse or acuminate entire or 

 denticulated scales, segments |-1 inch long 1^-2 lines wide 

 diminishing from the base to the apex or the lowest ones 

 a little alibreviated, the superior base broader, inferior base 

 attenuated and decurrently adnate and confluent by means of 

 a narrow wing elongato-oblong obtuse or lanceolato-oblong 

 generally entire, sori impressed generally near the apex of 

 the segments 4-6 on each side the costule near the margin 



* A small but natural group, though varying in ramification; the frond, gene- 

 rally thick and opacpie, renders it difficult to detect the true character of the 

 venation, which is sometimes considered to be that of § Goniopteris.
