8 SCHIZAEACEAE 



skeleton-like, non-foliose, greatly elongate, erect, often 

 overtopping the rest of the blade, and bearing numerous 

 panicles of sporangia in 2 rows on the back of very 

 narrow divisions. A tropical genus of several dozen 

 species. Besides the following, another occurs in west- 

 ern and southern Texas. 



1. A. adiantifolia (L.) Sw. Plants 1 m. tall or 

 usually less: leaf -blades triangular-ovate, 12-30 cm. 

 long, on usually elon- 

 gate petioles, slightly 

 pubescent, pinnately 

 decompound; ultimate 

 segments obovate or 

 cuneate, striate above 

 with numerous flabel- 

 late veins: panicles 

 of the sporophyl as- 

 cending or erect, tan 

 or brown, hairy on 

 the back, continuous 

 or slightly inter-

This fern is more 

 common in pinelands 

 than in the hammocks, 

 but it usually grows 

 two or three times as 

 large in hammocks. 

 In Koyal Palm Ham- 

 mock it is rather widely distributed; but it is more 

 abundant in the southern and higher parts of the forest.
