Bulletin 3. The flora of the Raritan Formation, 1911 - State of New ...

SAPINDALES. 179
Description.--Leaves small, 3 an,. to 4 cm. in length by 1,4 cm.
to 3 cm. in breadth, ovate to broadly spatulate in outline. Apex
rounded m_re or less broadly. Base narrowed and decurrent.
Margins entire below, dentate _bove, the teeth usually confined
to the apical third of the leaf, Midrib usually somewhat curved,
giving the leaves an unsymmetrical appearance. Secondaries
6 to 8 pairs, branching from the midrib at an acute angle, curving
slightly upward, camptodrome.
The more narrow forms were separated from the broader
form,s by Prof. Newberry, both being given specific rank, although
it seems obvious that they a.re the variable extremes of
a single species, and that not an especially variable one. They
approach rather closely to Cdastrophyllum Brittonianu4n` Hotlick,
but are readily distinguishable by their less symmetrical shape
and narrower base, their coarser an& less numerous teeth, and
their usually more numerous, more ascending, and straighter
secondaries.
No localities for this species are given i_ Prof. Newberry's
Monograph. Later collections show. it to be abundant in the
upper Raritan at South Amgoy.
Occurrence.--South ,A__boy.
Collectlons.--U, S. National Museum,, N. Y. Botanical Garden.
