that more complete material may be collected in the future, when 
we may be able to differentiate them.

ZIZYPHUS ELEGANS n. sp. (PI. 177, f. 9, 10.) 
Leaves ovate, varying in size, (about I in. long, t& in. or less 
wide), entire, symmetrical; nervation palmate; midrib slender, 
sparingly branched above; lateral primaries more slender, curving 
strongly from the base upward, branched on the outside, branches 
curving upward, all apparently eventually loosing themselves 1m 
the parenchyma of the blade. , 
Numerous fragments of these beautiful little leaves were found, | 
which I have been unable to refer to any described species.
