272 POLYPODIUM, § PHEGOPTERIS. 



mary coriaceo-membranaceous pinnsc a span to a foot long, glanduloso-viscid be- 

 neath, together with a portion of the main rachis ; this latter is as thick as a 

 goose-quill, striato-sulcate, and, as well as the secondary rachises and costae, 

 densely pubescent, not sensibly glandular, the pubescence mixed with many scat- 

 tered, small, subulate, dark-brown scales ; secondary pinnae 2^-3 inches long, 

 sessile, from a broad base, oblong, gradually acuminate, ])innated below, pinnatifid 

 in the upper half; segments oblong, subentire ; pinnules ^-f of an inch long, 

 adnate, with subdecurrent base, ohlong, obtuse, lobato-pinnatifid ; lobes rounded ; 

 venation obscure ; sori copious, scattered, often marginal, and often two or three 

 on each lobule. In habit it resembles a large form of P. rugulosum, yet it seems 

 quite distinct. 



223. P. (Phegopteris) rugulosum, Labill. ; caudex long 

 creeping rufo-villous rather than in any way scaly, whole 

 plant more or less hairy and glanduloso-viscid especially be- 

 neath, stipes 1-2 feet and more long varying in size from a 

 crow's to a swan's quill and as well as the main rachises 

 glossy and rough with elevated points bright castaneous or 

 stramineous, frond often small but varying from 6-8 inches in 

 length very slender (perfect and fertile) to 3-4 and more feet in 

 length, from 4 inches to 3 feet wide at base, deltoid-ovate sub- 

 coriaceous (rarely submembranaceous and flaccid) tripinnate, 

 primary pinnae generally in distant petiolated pairs, lowest 

 primary pinnae (in a specimen now before me) 18 inches long 

 and 10 inches wide oblong-ovate acuminate, secondary pinnae 

 1-4-5 inches long sessile from a broad base oblong- 

 acuminate, pinnules ^-| of an inch long oblong or linear- 

 oblong obtuse lobato-pinnatifid with small rounded lobes 

 rarely angulato-dentate at the margin, veinlets once or twice 

 forked within each lobe, the lower superior branch extending 

 to the margin at the sinus of the lobes and there bearing a 

 solitary sorus but so copious (10-14 on each pinnule) that 

 they frequently cover the whole under-surface of the frond, 

 secondary rachises terete not winged. — Labill. Fl. Nov. Holl.
