Altogether ten species of Philonotis (Hedw.) Brid. have been recorded from Mt.
Kilimanjaro, however only six of them are confirmed. The Kilimanjaron
specimens named as P. fontana
and P. tomentella differ from the
representatives of the high arctic to boreal populations, and are excluded. A
key to the accepted species and descriptions and illustrations of P. schroederi and P. tricolor are provided. P. platyneura is synonymized
with P. tricolor. The relationship of P. globosa
with P. schroederi needs a further study and
the presence of P. dregeana on Kilimanjaro
needs to be confirmed. Additional notes are given of P. falcata
(W.J. Hook.) Mitt., P. heleniana (Mitt.)
Herz., P. helenica (Besch.) Par. and P. usambarica Broth. Lectotypes are designated for
P. tricolor and Bartramia gemmascens Müll.Hal. (= Philonotis gemmascens)
and Philonotis section Leiocarpus
Broth. The taxonomy of the sections of Philonotis
is discussed; two sections, Philonotis and Philonotula (Bruch, Schimp.
& Gümbel) A. Jaeger include
most of the species. P. dregeana
(Müll.Hal.) A. Jaeger, P. gemmascens (Müll.Hal.) Par., P. globosa (Müll.Hal.) D.G. Griffin & W.R. Buck, P.
marangensis Broth. (= P. hastata (Duby) Wijk & Margad.) and P. schroederi Broth. belong to the section Philonotula.
P. fontana (Hedw.) Brid., P. platyneura P.Varde, P. tomentella Molendo and P. tricolor (Müll.Hal.)
Par. are the species of the section Philonotis.
