Leaves generally large, simple, cuneate-spatulate, linear-spatu- 
late spatulate or obovate.cuneate in form, round, obtusely rounded 
or narrowly rounded at the apex, cuneate, often with concave 
borders below, to the generally narroto base; lamina thick, often 
convex ventrally between the nerves; nerves distinct and rather 
strong, numerous, erect, parallel, and a little distant at the base, 
forking repeatedly at a very acute angle while curving slightly 
outward, the true veins passing, very distinct and generally about 
bmm—limm distant, to the border which they meet very obliquely 
except in the rounded apex of the leaf; hypodermal strands slen- 
der, straight, fairly regular and parallel, usually 2 or 4 in num- 
ber between each pair of nerves, and usually entirelly immersed 
and invisible in the thick lamina. 
The specimens representing this species in the Braziiian collections 
agree both in the variation in form and in the nervation with the leaves 
so abundantly illustrated in the reports (1) on the Gondwana flora. The 
larger specimens are truly Cordaitean in their aspect and proportions. 
This is illustrated in the original of Pl. IX, Fig. 5, which is compa- 
rable to those from the Talchir-Karharbari series shown in plates xxviii 
and xxix of the third volume of the Gondwana Flora. The broadly roun- 
ded apex seen in our Fig, 4, has its counterpart also in the same plates 
of Feistmantel’s great work. The lack of symmetry seen in this type is 
characteristic of the Cordaitean group. Other examples in the collection, 
from the same locality, exhibit the smaller forms with narrow apices 
such as those illustrated by Feistmantel in plate xix of the report just 
cited, or that shown in fig. 41, plate xviii, of the South Rewah me-
