Information
Rhizome shortly creeping with filiform scales ± 8 mm long, chestnut or dark with narrow pale margins. Fronds 8–20, tufted, 20–45 cm tall; stipe purplish black, 5–20 cm long, glabrescent to densely spreading grey-pubescent and with black scales at base; lamina narrowly oblong to lanceolate, 8–39 cm long, 2.5–12 cm wide, simply pinnate with (3–)10–24 pairs of pinnae, or the lower ones sometimes again pinnate, often with only 3(–6) pinnules; pinnae or pinnules ovate or elliptic to oblong or oblong-lanceolate, sometimes narrowly so, 1–5.5 cm long, 0.2–2.5 cm wide, densely pubescent beneath and glabrous or hairy at base above or sparsely hairy all over; sometimes more or less glabrous all over (see notes); veins entirely free or sometimes with a very few anastomoses; sterile margins crenate. Sori and indusium continuous.

Notes
I have checked the venation in topotypic material from Rejaf and it is entirely free. Some specimens of P. longipilosa and some of P. dura var. schweinfurthii are so similar in appearance that it is difficult to believe they are separate species. It is certainly inconvenient that the venation cannot be seen usually without chemical clearing or strong transmitted light, methods difficult in the field. Moreover, specimens do occur in which the venation is not entirely free. Burnett 49/55 (Ufipa District: Rukwa, Milepa, Jan. 1949) has been labelled ‘ P. longipilosa subglabrous form’ by Schelpe; it is strongly bipinnate with ultimate pinnules up to 3 cm long, 0.7 cm wide. I am not sure how this and several similar specimens are related to the various simply pinnate specimens from the same general area, which have been treated as slightly pubescent forms of P. doniana or P. doniana / longipilosa intermediates. Populations studies are needed in this area. Throughout a very wide area P. doniana is always simply pinnate and glabrous but this too needs checking in the field.Several specimens are partly bipinnate, glabrescent and have up to 3 anastomoses per pinnule e.g. Proctor 2258 (? Mbeya District, 48 km from Chunya on Itigi road, Jan. 1963). Bidgood et al. 2021 (Masasi District, 8 km NE of Masasi, Mkwere Hill, 16 Mar. 1991) is simply pinnate with about one anastomosis per pinnule and close to P. doniana. Bidgood et al. 1814 (Masasi District, Ndanda Mission), is clearly the same taxon with one or two anastomoses and some bipinnate areas at base of lamina. The three species mentioned in this certainly need further study particularly in S Tanzania. Ali Omari in Richards 15319 (said to be from E Usambaras, Monga, Calini Tea Estate “6000 ft” (actually about 900 m), 20 Aug. 1961, is from a rain forest area if the locality is correct. Once again there is one anastomosis near base on one side of some pinnules. Schippers 992 is also from the same area, between Amani and Sigi, 30 Aug. 1985.
