A more distinct variety is 



Var. densestriata var. nov. — Fig. 2. 9 — 10. 



Frond about as in the typical form, more deeply lobate 

 with undulate-repand edges, thicker in texture. Spurious 

 veins very dense and numerous, 6 — 8 or more between 

 two true veins.

Trichomanes Lenormandi V. d. Bosch.

 T. Kirkii Hook. — T. erosum var. laciniata Mett.; Kuhn, 

 Fil. Afr. 34 (an part.?). — Fig. 2. 11—25. 



To this species I refer several spécimens, which seem 

 to agrée very well with the original descriptions and 

 figures of V. d. Bosch except in size. My figures give a 

 better idea of the species than any description; the largest 

 spécimens are 4 — 5 cm long (incl. stipe) and nearly 2 cm 

 wide, deltoid or oblanceolate in outline, the base long 

 decurrent. From T. cuspidatuni, with which it is often con- 

 founded, it is very différent by its distinctly pinnate vena- 

 tion with most of the sori latéral, the more indistinct, 

 characteristically flexuose intramarginal vein, that is often 

 interrupted, and by the numerous short spurious veins in 

 the parenchyma, which rarely are united with the intra- 

 marginal vein; further by its cylindrical indusia, the mouth 

 of which is very slightly dilated. B}' this latter character 

 it also differs from the West African T. erosum, to which 

 Mettenius referred it as a variety.
