might be called Schizoneura (?) africana. I have elsewhere 

 expressed an opinion that the South African specimen agrees 

 closely in certain respects with the Indian species of Schizoneura. 

 At the same time this plant is too imperfectly known to attempt 

 a satisfactory specific description. 



Schizoneura (?) africana is known only from South Africa. 

 Some fragments from German East Africa have recently been 

 doubtfully referred to this genus by Potonie. 1 The plant figured 

 by him is a cast of a stem showing ribbed internodes. It is, 

 however, well known that it is impossible, in the absence of leaves, 

 to decide whether such casts should be referred to Schizoneura or 

 Phyllotheca. Similar specimens have also been described by 

 Seward 2 from Cape Colony, Transvaal, and Natal. 



41,285. A very obscure specimen, probably identical with 

 S. africana of Feistniantel. Although there is no record, this 

 specimen is probably one of those collected bv Bain. It shows 

 portions of three leaves, each with several parallel veins, obscurely 

 united into a sheath at the base. The apex of the segments is 

 not seen.

Stem unknown. Leaves whorled. United at the base, and for 

 about two -thirds of their length. Whorls disc -like, spreading 

 horizontally, elliptic. Free segments numerous, 80 or more in 

 a whorl, uninerved, often transversely wrinkled near the apex, 

 unequal in length. 



Feistmantel referred the single known fragment of this plant to 

 the genus Actinopteru, instituted by Schenk 3 for the reception
