Descrlption.--Leaves <strong>of</strong> medium size, elliptical in outline, pinnately<br />

lobate or pandurifom_. Lobes obtusely rounded, separated<br />

by shallow rounded sinuses <strong>of</strong> variable width or <strong>the</strong> margin may<br />

be strongly undulate with two or three broad scallops, or one<br />

margin may be lobate and <strong>the</strong> o<strong>the</strong>r scalloped. Apex obtusely<br />

pointed. Base pointed, slightly decurrent. Petiole stout, 2. 5 cm.<br />

in len_h. Leaves ver3, variable in size and outline, ranging from<br />

4-5 era. to 7.5 cm. in length by _ era. to 4 cm. in breadth. Basal<br />

half or one-third 04 <strong>the</strong> leaf entire, this feature with <strong>the</strong> ascending<br />

opposite basal secondaries giving fragmentary specimens <strong>the</strong><br />

appearance <strong>of</strong> a Cimm,wmmg or a Sassafras. Midrib mediumly<br />

stout. Secondaries few, not more than 2 or 3 pairs, branching<br />

from <strong>the</strong> midrib at an acute angle, curved, indifferently camptodrome<br />

and craspedodrome; <strong>the</strong> basal pair are subopposite<br />

branching from <strong>the</strong> midrib a short distance above <strong>the</strong> base and<br />

curving upward; <strong>the</strong>y traverse _ or _ <strong>the</strong> distance to <strong>the</strong> apex<br />

ending in <strong>the</strong> tip <strong>of</strong> <strong>the</strong> lowest lobe or camptodrome, this variability<br />

i_ <strong>the</strong>ir course is well shown in <strong>the</strong> specimen figured; <strong>the</strong><br />

o<strong>the</strong>r secondaries may be alternate or sub-opposite, and <strong>the</strong>y may<br />

end in a lobe or not; <strong>the</strong> second one is a considerable distance<br />

above <strong>the</strong> basal pair, as much as 2. 5 cra. in one specimen, and it<br />

subtends a somewhat wider angle with <strong>the</strong> midrib.<br />

<strong>The</strong>se curious leaves are not uncommon, but are mostly incomplete.<br />
