DESCRIPTION OF SPECIES. 93 
identical with that of some species of Bauhinia, e. g., B. tomentosa, now 
living in India. The other lobe is not much more than half as long, is 
truncated, and in all probability abnormal. When other specimens are 
found I shall be surprised if they are not symmetrical and so much like 
the leaves of Bauhinia that it will be impossible to separate them from this 
genus. It will, however, prove to be, if generically identical with our 
bilobed Amboy leaves, specifically different, for the sinus extends almost to 
the base of the leaf. Some of the living species of Bauhinia are almost 
completely divided in the same way, and this is the case with Bawhinia 
lunarioides, as has been mentioned.

Leaves large, a single lobe or leaflet, 20° long by 7°™ or 8™ wide, 
unsymmetrically spatulate in outline, inner margin nearly straight and 
entire, outer margin strongly arched and undulate; nervation distinct, con- 
sisting of one strong primary nerve springing from the inner margin at the 
base, gradually diverging from this until it becomes central in the rounded 
summit; lateral nerves spring from this as follows: one of medium strength 
at the base which follows for a time parallel with, finally approaching, the 
outer margin, and having a length of perhaps 5°; above this a strong lat- 
eral nerve is given off 2° or 3°" above the base; this arches gently upward 
and reaches the outer margin considerably above. the middle of the leaf; 
still higher smaller lateral nerves are given off to supply those portions of 
the leaf which lie on both sides of the primary nerve. 
Unfortunately, but two specimens of this interesting leaf have yet 
been found, only one of which is complete. This is conspicuously unsym- 
metrical and was probably one of a pair which combined to form a leaf 
not unlike those of Bauhinia cretacea, but much more deeply cut. It is not 
certain, indeed, that the lobes were not separated quite to the base, as in 
the living Bauhinia lunarioides. The nervation is nearest that of Bauhinia 
eretacea, but shows this marked difference, that the principal nerve is much
