Anemia guatemalensis Maxon

Anemia guatemalensis Maxon, sp. nov
Rhizome wanting ; stipes of the fertile fronds mostly longer than the detached sterile fronds. Fertile fronds 30^5 cm. long ; stipe stout, 23-30 cm. long, erect, yellowish, very densely clothed with subpersistent spreading dark-rusty hairs ; sterile lamina deltoid, 12-16 cm. long, 10-12 cm. broad, acute, tripinnate below, deeply tripinnatifid nearly throughout, the rachis conspicuously ferruginous-pilose ; pinnae about 10 pairs, spreading or ascending, contiguous or imbricate, short-p etiolate, mostly ovate-lanceolate or the lowermost narrowly deltoidovate, these the largest, 6.5-7.5 cm. long, 2.5-3 cm. broad near the base, with 8 or 9 pairs of oblong-lanceolate pinnules below the short subacute crenately lobed apex, the larger of these pinnate at the base, above deeply pinnatifid with about 4 pairs of segments, the basal ones crenately lobed ; upper pinnae gradually simpler, the pinnules short-stalked or sessile, only those of the uppermost pinnae finally adnate ; leaf-tissue rigidly chartaceomembranpus, thickish but translucent, dull-green above, lighter or yellowish-green below, obscurely glandular above, conspicuously so below, the upper surface glabrate, the lower conspicuously rusty-pilose along the secondary rachis, costae and veins ; veins concealed or somewhat impressed above, scarcely evident below ; margins slightly thickened ; fertile pinnae stout, erect, 13-15 cm. long, nearly or quite as long as the sterile lamina, the stalk very short (2-2.5 cm. long), the panicle with numerous strict erect branches, the lowermost of these up to 4.5 cm. long with short pinnate divisions, the upper branches gradually shorter and closer, the uppermost densely crowded; spores striate, the angles not produced. Sterile fronds 16-33 cm. long ; stipe 8-9 cm. long ; lamina 10-18 cm. long, 9-15 cm. broad, ovate-deltoid or subpentagonal, the basal pinnae strongly basiscopic, spreading, unequally deltoid, the inferior basal pinnules oblong-ovate, in the largest specimen 3.8 cm. long and 1.9 cm. broad, with about 5 pairs of ovate-oblong pinnatifid or lobed segments below the trilobate apex, the lowermost sessile; pinnules mostly anadromous, only those of the upper third of the lamina catadromous.
