(192) ^. PoilZOlxiana, Spring. 



According to Spring's diagnosis this species is said to have the 

 axillary leaves obovate, narrowed at the base, and the lateral leaves 

 entire. The specimens occurring in the Buitenzorg Herbarium have the 

 lower axillary leaves broadly cordate to ovate, broadest at or near the 

 base, and the lateral leaves often, if not invariable, very minutely 

 denticulate-serrulate towards the apex. 



Forma typica : Lower pinnae broadly ovate or triangular-ovate ; lower 

 pinnulae broad, conspicuously pinnate to 2-pinnate, the higher simple or 

 forked; macrospores verruculose, whitish or pale-brown when young, 

 grey-brown or black-brown when adult; micropsores whitish or yellowish, 

 provided with more or less crowded, bacilliform or stipitate-capitate 

 projections.
