48. HEMITELIA, B. Br. (emend.). 



Son globose, dorsally inserted beyond the forking or near the marginal summit of simple 

 veinlets : indusium dimidiate-inferior, broadly embracing the sorus, persistent : receptacle 

 prominent.— Leaves pinnatisect, rarely 2-pinnatisect : vemlets of Cyathea, but the lowest 



^SmlTptTerXsenting the habit of Cyathea and Alsophilal exclude from Hemitelia 

 (e. g. H. capensis,Parkeri, guianensis, etc.), and, according to the insertion of their son, 

 would transfer them to Alsophila, near A. aspera: hence my Hemitelia n the same as 

 Cnetnidaria, Pr., while Hemitelia, Pr., is drawn to A Isophtla. An exception however to 

 this arrangement (as often occurs at the limits of Feni-genera) is presented by ^/^« 

 TTeigeltiala, Roem. (PI. Kappler. 1355): for in this specie. I find the son d.ffercntly
