species forms the typical undergrowth where the pine barrens 

 are frequently burned over. It is the only fern of the dry, lightly- 

 wooded sea islands and is characteristic of the open grassy bor- 

 ders of the jungle on more densely covered islands. Spores ma- 

 ture in May. 



The variety pseudocaudatum Clute is well represented by a 

 specimen from the Santee country, collected by Ravenel and 

 labeled by him P. caudata. Bachman's P. caudata must also, in 

 all probability, be referred to this form. I have, however, searched 

 extensively but unsuccessfully for a distinct variety in the vicin- 

 ity of Charleston.

Asplenium platyneuron (L.) Oakes. Ebony Spleenwort. 

 One of the most common ferns. Associated with Pteris serru- 

 lata on old walls in Charleston. Grows luxuriantly on wooded 

 banks, and particularly along artificial ditches. Fertile leaves 

 measuring four to five inches wide and twenty inches long, with 

 deeply serrate pinnae, are characteristic of highly developed 

 plants. Spores mature in May.
