Names
PSOROSPERMUM febrifugum (Hook f.) Keay & Milne-Redh. var. ferrugineum [family GUTTIFERAE], in K.B. 1953: 290 (1953). Type: Sierra Leone, Freetown, G. Don (K, holo.!)
PSOROSPERMUM ferrugineum Hook.f. [family GUTTIFERAE], in Hook., Nig. Fl. 241 (1849)
PSOROSPERMUM febrifugum [family GUTTIFERAE], sensu Engl. in P.O.A. C: 274 (1895); V.E. 3 (2): 502 (1921); F.W.T.A. 1: 232 (1927); T.S.K., 36 (1936); T.T.C.L. 250 (1949); I.T.U., ed. 2, 159 (1952), excl. spp. Eggeling 1521 & 1783, non Spach sensu stricto
Information
Stems densely rusty-tomentose. Leaf-blade densely rusty-tomentose below, the indumentum sometimes becoming sparse in age revealing (in the dry state) a conspicuous reticulation. Pedicels and outside of calyx densely rusty-tomentose. Fig. 4/1–14, p. 17.
Range
DISTR. U2, 4; K7; T1, 4-7 widely spread in tropical Africa.
Altitude range
50–1950 m.
Distribution
KENYA Kwale District Shimba Hills, May 1930 (young fr.), Donald 36TANGANYIKA Buha District Kitolo, 22 km. N. of Nguruka, 5 Oct. 1949 (fl.), Bally 7635!;TANGANYIKA Morogoro District Uluguru Mts., 3 Jan. 1935 (fl.), E. M.

Notes
VARIATION. PS. febrifugum Spach, as recognized here, shows great variation in degree of indumentum, in leaf-shape and in size of inflorescence, with no apparent correlation of these characters. For convenience, I have recognized two varieties based on indumentum. Each shows considerable range in leaf-shape and size of inflorescence. Specimens may be found with characters more extreme than, as well as intermediate between, those of these varieties. Ps. febrifugum defies orthodox taxonomic treatment, and should prove a profitable subject for the experimental taxonomist.
