2 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 6l 



imbricate ; venation wholly areolate, the meshes small, mostly hexag- 

 onal, without included veinlets, arranged in many rows, successively 

 smaller outward, not attaining the margin ; sporangia borne upon and 

 immediately beyond the outermost row of areoles in a continuous 

 slightly intramarginal band, partially concealed by the scales ; indusia 

 wanting. 



Type species, Saffordia induta Maxon. 



SAFFORDIA INDUTA Maxon, new species. 

 Plants 15 to 25 cm. high, the fronds numerous (6 to 14), rigidly 

 erect, closely fasciculate; rhizome ascending or erect, short, 1 to 2 

 cm. in diameter, densely paleaceous, the scales closely tufted, light 

 castaneous in mass, concolorous, flaccid, linear, 5 to 8 mm. long, with 

 long slender tortuous subflexuous tips ; stipes stout, 9 to 18 cm. long, 

 1.7 to 2 mm. in diameter, firm, terete, purplish-brown, lustrous beneath 

 a dense covering of appressed imbricate detergible scales, these light 

 castaneous, lance-ovate, long-acuminate, sharply denticulate-fimbri- 

 ate, variable in size, the largest ones about 7 mm. long; lamina 5 

 to 10 cm. long, 5 to 11 cm. broad, deltoid-pentagonal, pinnately parted 

 to within 3 to 6 mm. of the costa, the basal pair of segments deltoid, 

 inequilateral, coarsely and deeply lobed upon the broad proximal side, 

 shallowly or not at all lobed upon the narrow distal side, thus strongly 

 basiscopic; other primary segments or lobes 2 or 3 pairs below the 

 short-caudate apex, opposite or nearly so, linear to linear-oblong, 

 oblique, straight or upwardly subfalcate, the margins entire, strongly 

 involute at maturity; leaf tissue thick, rigidly herbaceo-coriaceous, 

 glabrous above but scantily and deciduously squamulose along the 

 partially concealed slender costae, densely appressed-paleaceous be- 

 neath, the scales closely imbricate, persistent, similar to those of the 

 stipes, completely covering the lower surface (including the costse), 

 extending beyond the margin and commonly recurved as a regular 

 narrow border upon the upper surface ; venation areolate, without 

 included veinlets, the areoles small, mostly hexagonal, arranged in 

 5 or 6 rows upon each side of the costae, the costal ones elongate and 

 parallel to the costa, the others successively smaller, shorter, and more 

 oblique, not extending to the margin ; sporangia partially concealed by 

 scales, densely crowded in a continuous slightly intramarginal band 

 1.5 to 2.5 mm. broad, borne partly upon the outermost row of areoles 

 and partly upon the adjacent veinless area, about 0.5 mm. apart from 

 the unchanged margin ; indusia wanting ; spores subglobose, obscurely 

 triplanate, light brown, discontinuously areolate, the ridges very thin, 

 vermiculate.
