Description:
Species Description - Rhizome short-creeping, ca. 5 mm diam.; rhizome scales castaneous, lustrous, linear-lanceolate, toothed, 4-6 mm long; phyllopodia distinct, short; fronds clumped, 25-60 cm long, 1.4-3.1 cm wide; stipe 1/8-2/5 the frond length, with scales linear, tan, ca. 2 mm long, ciliolate, spreading, others smaller, stellate; blade narrowly elliptic, chartaceous, apex caudate, base narrowly cuneate; veins evident to obscure, free, simple to once-forked, ca. 1 mm apart, at ca. 70° angle; hydathodes lacking; blade scales orange, linear, very long-ciliolate, plane or spreading, loosely covering the lower surface, upper surface glabrous with age, with narrowly lanceolate scales with long hair-teeth or substellate with long teeth; fertile fronds slightly shorter or longer than the sterile fronds, stipe 1/3-½ the length, with a few reduced scales on abaxial midvein but not among the sporangia; spores with low broad, smooth ridges.

Discussion:
Acrostichum vestitum Schlechtendal & Chamisso, Lin-naea 5: 605. 1830. Type. Mexico. Veracruz: “Prope Jalapam. Aug.,” Schiede s.n. (B!). (Although there is no type specimen number cited with the description, there is a specimen at B (Schiede s.n.) with all the pertinent data of locality and date on it. There is also Schiede 735 but without data, so the former is presumed to be the type specimen.) Acrostichum fulvum Martens & Galeotti, Mém. foug. Mexique 24, t. 3, f. 2. 1842. Type. Mexico. Veracruz: Orizaba, Galeotti 6459 (BR!). Acrostichum laminarioides Fée var. a longipes Fournier, Mexic. pl. 1: 67. 1872. Syntypes. Mexico. Veracruz: Barranca de Agua Santa, 3000 ped, Heller 188 (P?), in regione Orizabensi pr. Santa Ana, Bourgeau 3060 bis (P!), Huatusco, Schaffner 32 “in herb. Fée,” in alle Cordobensi pr. La Trinidad, Bourgeau 2110 (P!), Jalapa, aug. sp., Hahn s.n. (P!). Acrostichum laminarioides Fée var. ß brevipes Fournier, Mexic. pl. 1: 67. 1872. Syntypes. Mexico. Veracruz: Huatusco, F. Müller 386, in valle Cordobensi, Schaffner 28, 31, pr. Fortín, Bourgeau 2199 bis, pr. La Trinidad, Bourgeau 2110 quater (P!). Elaphoglossum vestitum is most closely allied to E. rubescens Christ of Chiapas and Guatemala, resembling it in rhizome scale color and texture, ciliate blade scales lightly covering the lamina, and lax fronds with caudate tip. The latter can be distinguished by the rhizome scales not (or only weakly) toothed, the stipe often with resin dots, and the blade scales with the teeth and margins upturned. These two species may be only varietally distinct, overlapping in Chiapas with several intermediate specimens. Elaphoglossum auricomum belongs to the same complex but has more abundant, spreading stipe scales, the rhizome scales are lighter in color, and the blade has an acuminate apex. Some specimens of E. paleaceum have blade only lightly covered with scales, but they have black scales on the stipe and lower rachis.
