ABSTRACT

Ocotea, Cyathea-Ocotea-Podocarpus and Parinari-Newtonia-Ocotea-Macaranga; 1400-2100 m

SYN. D. pseudoporrectum Hieron. var. angustipinnatum Reimers in N.B.G.B. 11:922 (1933); Schippers in Fern Gaz. 14:205 (1933). Type: Tanzania, Morogoro District, NW Uluguru Mts, Schlieben 3108 (B, holo., BM!, iso.)*

NOTE. In Schlieben 3108 all the pinnae have retained the very shallowly toothed margins of the uppermost pinnae but new material shows variations in this respect. Some sheets of the species had been determined as D. silvaticum (Bory) Sw. and some Burmese specimens of that are very similar. It would be foolish to make suggestions without a revision of the Old World species.

FIG. 5. DIPLAZIUM PSEUDOPORRECTUM—1, rhizome,×⅔; 2, frond showing both surfaces, ×⅓; 3, pinna,×1; 4, venation, enlarged and diagrammatic; 5, indusium, enlarged and diagrammatic. All from Faden 74/386. Drawn by Pat Halliday.
