400 ENUMERATIO FILICUM PHILIPPINARUM, 



punctiform sori of Drynaria and the compound elongated 

 marginal sorus of Drymoglossiim on the same frond. This 

 double character goes some length to confirm a former obser- 

 vation of mine, that the elongated transverse sori of Taenitis 

 and its allies, as also the elongated oblique sori of SelUyuea, 

 are formed by a coalition or prolongation of soriferous points. 

 Such a view proves the affinity of these genera with Drynaria.

Obs. The uniform smalluess of the whole of the specimens 

 of this No. is hardly characteristic of its being a distinct spe- 

 cies, and probably it is only a small state of Antrophyum 

 reticulatum.
