§§§§§ Microlepia. Invol. membranaceous, shallowly half-aipshaped, attached at 

 the sides as loell as the base. Sp. 50-65. Fronds very various in size, texture, and 

 cutting. This sub-genus has its head-quarters in S. E. Asia and Polj/nesia. Four 

 species are American and one African. Differing also from Humata, Eudavallia, 

 and Leucostegia, in having the stems, except in D. ciliata, continuous with the 

 caudex, and consequentli/ falling under a different primary division {^Desmohrya') of 

 J. Smith'' s classification,

 towards the point ; texture subcoriaceous ; rachis and veins beneath villose ; sori 

 in continuous rows along the edges ; invol. small, about as broad as deep. — Hk.
