ADIANTUM concinnum Willd. [family ADIANTACEAE], Sp. Pl. 5: 451 (1810); Sledge in Ceylon J. Sci (Bio. Sci.) 10: 152, fig. 11 (1973). Type: Venezuela, Caracas (‘Cumaná’), Humboldt & Bonpland s.n. (B-W 20099-2, lecto. chosen by R.M. Tryon in Contr. Gray Herb. 194: 168 (1964) (microfiche!)
Information
Rhizome thick, compact or shortly creeping; scales uniform brown, linear-lanceolate, (1.5–)3–4 mm long, 0.8–1 mm wide, entire. Fronds tufted, arching or pendent, 20–95 cm long; stipe chestnut-brown to purple-black, 1/4 to 1/3 the length of the frond, shining, glabrous, with a few broad scales at the base; lamina lanceolate to ovate-lanceolate, 6–25 cm wide, long-attenuate at the apex, 2–3-pinnate; pinnae in 10–15 pairs, gradually reduced, alternate, glabrous, the basal pinnule overlapping the rhachis; pinnules obovate to oblong or rhombic-ovate, 0.7–2.5 cm long, 0.5–1.8 cm wide, cuneate at the base, shortly stalked, the colour of the stalk running into the segment base, glabrous, lobed and incised, the veins running into the sinuses; sterile segments denticulate. Sori kidney-shaped; indusium often whitish, 1–1.5 mm wide, glabrous, thin, entire with abruptly flaring margins.
Range
DISTR. T 3 central America, western S America and West Indies, introduced elsewhere and occasionally naturalised e.g. in Sri Lanka
Altitude range
460 m
Distribution
TANZANIA Lushoto District Sigi [Zigi], old plantations on Amani to Muheza road, 1 July 1970, Faden et al. 70/303! & same area, 30 Aug. 1985, Schippers 998A!, 998B!
Notes
At first I considered these specimens to be A. raddianum cv. Pacific Lady but have decided they are close to A. concinnum. The cv. may have been attributed to the wrong species. Other specimens seen are Johns & Bradley 8707, 8708, 8681 but no field are available.
