CHAEACTEES OF TEIBES AND GENEEA. 293 



As a genus Loncldtis is distinguished from LitohrocJda by 

 the sori being seated in the sinus of the lacinse, thus form- 

 ing a semicircle or crescent, and also in the pubescent 

 character of the caudex and fronds. 



In the " Species Filicum " six species are described, but 

 which in the " Synopsis " are reduced to one, a new 

 described species is, however, added, namely, L. occidentalis, 

 Baker. The following species appear to me to be specifi- 

 cally distinct, two of which have been under my notice in a 

 living state. 



L. aurita, Linn. (L. Lindeniana, HooJ;.) (v v.) ; L. pubes- 

 cens, Willd. (v v.) ; L. Natalensis, Hooh. 



The first is a native of Mauritius, the two latter of 

 Mauritius and Natal, 



167.— Campteria, Presl. (1836). 

 Pteris sjj. auct., Hook. <Sj.>. Fil. 



Vernation fasciculate, erect. Fronds long stipate, pin- 

 nate, 2 to 3 feet high ; pinnas piunatifid, the lower pair bi- 

 partite, or with one or more pinnules on the inferior side ; 

 lacinfB linear oblong, falcate, entire, or serrulate. Vei'im 

 forked, the lower pair of venules anastomosing, forming a 

 straight arcuate costal arch between the bases of the lacinie, 

 the rest of the sterile venules being free, the apices of the 

 fertile combined, formiag a linear, transverse, marginal 

 sporangiferous receptacle, seated in the axis of an inflexed 

 linear, special indusium.

Obs. — The species on which Presl founded this g-enus 

 agree in general habit with Pleris qtiadriaurita and its
