To this species I refer ail spécimens that hâve a distinct 

 intramarginal, continuons vein, from which run shorter or 

 longer, rarely interrupted spurious veins parallel to the 

 true veins. The fronds are variable in shape and size; 

 generally they hâve a broadly cuneate base, rarely long 

 decurrent; fan-shaped fronds as those of T. Bojeri Hook. 

 et Grev. le. Fil. tab. 155 I hâve not found among the 

 spécimens from Madagascar. The stipe of full-grown leaves 

 is so long as the lamina but in smaller leaves often much 

 shorter. The veins are flabellate or, in narrower leaves, 

 pinnate. The sori are confined to the upper edge of the 

 frond; the indusia hâve the mouth distinctly dilated and a 

 narrow cylindrical tube. 



The following spécimens I regard as rather typical, 

 although some of them look rather différent; especially 

 remarkable is a short-stalked form (n° 7745 D), which has 

 not only the rhizome and stipe but also the midrib rather 

 densely rufo-tomentose.

The following form is perhaps worthy of the name 

 forma minor. Frond much smaller, ovate-oblong or oblong- 

 lanceolate, more long-cuneate at , base, the lamina 0,5 — 1 

 cm long, under 0,5 cm broad. — Fig. 2. 6 — 8.
