Mielichhoferia bequaertii Dix. & Nav., Bull. Soc. Bot. Belgique 60: 35. 1927. Type: KENYA. "Ruwenzori (Lanuri) ±400 m, 29 May 1914 [J. Bequaert] 4573" (lectotype BM!).

Gametophytically, this species is like a large version of P. nutans (Hedw.) Lindb. The plants are paroicous, rather dull, with thick-walled, non vermicular cells 30-65 µm long and 6-9 µm wide. Pohlia bequaertii is distinguished by an obliquely rostrate operculum, tiny capsule mouth and complete lack of a peristome. It is the only known eperistomate species of Pohlia, but its aflfinity with that genus rather than with the Mielichhoferioideae is indicated by terminal inflorescences with the perichaetial bracts gradually but significantly enlarged as compared to lower stem leaves. Stems of P. bequaertii, like those of many other species of Pohlia, are most commonly unbranched, but sometimes bear subfloral innovations. The absence of a peristome, certainly a derived feature, suggests that P. bequaertii may be a neoendemic derived from some Pohlia resembling P. nutans.
