Tingia taeniata Darrah sp. nov. 2 figures. 
Shoot dorsiventral, frond-like, anisophyllous, with 
stout axis. Leaves arranged in four rows, two on the 
lower side of the axis and two on the upper side, the 
latter forming an angle of 80—45° with the axis. Leaves 
of the rows on the upper side large and spreading in one 
plane, gradually diminishing in size terminad. Apex of 
the leaves slightly dissected and lobed. Veins broad and 
conspicuous, bifurcating several times near the base of 
the leaf and running in parallel directions to the apex of 
the leaf. 
The specific name indicates the linear, ribbon-like 
shape of the leaves. 
This species is related to Tingia carbonica (Schenk) 
Halle, but it differs in its much stouter axis, coarser 
veins, and its more linear leaves. It may be compared 
with Halle’s plate 62, figure 5 (Schenk’s type of Ptero- 
phyllum carbonicum) and plate 68, figures 4 and 5. Tin- 
gia taentata resembles 7. crassinervis Halle in having a 
very stout axis and coarse veins, but differs in having 
more numerous veins and in the linear shape of the leaves.

Tingia kempiae Darrah sp. nov. 2 figures. 
Shoot dorsiventral, frond-like, anisophyllous, with a 
very thick axis and four rows of leaves. Leaves of the 
two rows of the upper surface spread in one plane and 
forming an angle of 60-80° with the axis. Leaves with 
a broad base, oblong-oblanceolate, three to four times as 
long as the greatest width. Veins numerous (more than
