CHARACTERS OF TRIBES AND GENERA. 293 
As a genus Lonchitis is distinguished from Litobrochia by 
the sori being seated in the sinus of the lacinæ, 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, Hook.) (v v.) 3 L. c di 
cens, Willd. (v v.) ; L. Natalensis, Hook. 
The first is a native of Mauritius, the two latter of 
Mauritius and Natal. 
167.—Campreria, Presl. (1836). 
Pteris sp. auct., Hook. Sp. Fil. 
Vernation fasciculate, erect. Fronds long stipate, pin- 
nate, 2 to 3 feet high ; pinnæ pinnatifid, the lower pair bi- 
partite, or with one or more pinnules on the inferior side ; 
lacins linear oblong, faleate, entire, or serrulate. Veins’ 
forked, the lower pair of venules anastomosing, forming a 
straight arcuate costal arch between the bases of the lacinæ, 
the rest of the sterile venules being free, the apices of the 
fertile combined, forming a linear, transverse, marginal 
sporangiferous receptacle, seated in the axis of an inflexed 
linear, special indusium.
