Descriptions of the Species. 
2 I I 
Rock grown specimens correspond entirely with Asplenium 
Ceterach, Linn. (Ceterach officinarum, Willd.), while plants grown 
under bush are widely different, but there is every gradation 
between. 
In Ceterach the veins anastomose more or less, while in our 
plant they are generally free ; but plants with some veins united 
are not uncommon. Though there is no true indusium in this 
species there is a row of scales covering the sori, and the whole 
under surface is more or less thickly set with scales. It varies a 
good deal, rock grown specimens being three inches long or less, 
leathery in texture and densely scaly ; while under trees or bushes 
it becomes six to nine inches long, thinly membranaceous in texture, 
and with very few scales. In some specimens it is also more 
deeply cut than in others. It curls up when dry and again unfolds 
when damp in the same way as Polypodium incanum. Dr. 
Atherstone’s specimens from Currie’s Kloof are much more 
shaggy than usual with brown scales a quarter-inch long.
