ments distant and bead-like during drought or heat. 

 Under moist conditions, however, these are open, flat, 

 and crowded, and when mature densely crowded, brown, 

 and sometimes fully occupied with brown capsules under 

 fringed scarious indusia, the frond then having a totally 

 different appearance from the delicate-green young 

 fronds. In both species the indusium is intra-marginal, 

 as shown in " Ferns of South Africa," Plate XXXI., 

 Fig. 3, though in the revolute state caused by dry atmo- 

 spheric conditions the green margin is reflexed over and 

 almost or quite hides the scarious indusium. 

 The Transvaal and Ehodesian specimens are mostly C.
