To T. Lenormandi I refer the following two varieties: 



Var. angustiloba var. nov. — Fig. 2. 21 — 23. 



In habit like the type, but frond often crisped and the 

 veins more flabellate, the sori are placed at the tips of 

 segments that are very narro^v, so that the sori appear 

 to protrude beyond the leaf-tissue; they are, however, 

 margined by a narrow wing of leaf-tissue. A single leaf 

 of n" 7732 is deeply pinnatifid with irregular, crisped seg- 

 ments, some of which are much lengthened (nearly 2 cm 

 long by 1.5 — 2 mm broad) and are again pinnatifid with 

 1 — 2 threadlike secondary segments.

 Manongarivo. entre 1000 et 1600 mètres d'altitude. H. 

 Perrier de la Bâthie, n" 7732 et 7738 part., Mai 1909. 



Var. subcuspidata var. nov. — Fig. 2. 24 — 25. 



A critical form, more thin-leaved than the two former 

 and the spurious veins are fewer but much longer and 

 often united with the intram arginal vein as in T. cuspida- 

 tum, still there are also shorter free spurious veins which 

 very rarely are found in T. cuspidatum. Further it differs 

 from tliat species and from T. erosum by its indusia, which 

 agrée very well with those of T. Lenormandi. 



Madagascar: Région floristique du Sambirano. Grande 

 Terre. Montagnes à l'Est d'Ambo . . ., vers 300 mètres 

 d'altitude. Sur les troncs de fougères arborescentes. H. 

 Perrier de la Bâthie, n° 7733, Septembre 1908. 



Trichomanes Kirkii Hook. Syn. Fil. 78. — Fig. 3. 



Baker believed this to be the same as T. Lenormandi 

 V. d. B., and unfortunately I followed him in "Index Fili- 

 cum" and united it with the species of Van den Bosch.
