DESCRIPTION OF SPECIES.

Qo 
Order MAGNOLIACE#. 
Maewouta Lacoreana Lesq.’ 
PUSXOVer tess ly: 
Leaves round-ovoid, 15°" long by 10°™ wide, blunt-pointed at summit, 
slightly wedge-shaped at base; nervation regular and characteristic of the 
genus, midrib slightly flexuous, lateral nerves almost uniformly spaced, 
simple until they approach the margins, when they connect in a regular and 
graceful festoon. 
We have too little material which we can consider as representing this 
species to insist upon its definition or classification. The two specimens 
represented in the figures now given are from the same locality and presum- 
ably represent the same species; but if so, we have no other representatives 
of that species, and if not, the two leaves belong to two species of which 
we have no other traces in the collection. Though in a somewhat different 
state of preservation, they agree well enough as regards their form and 
nervation, and it has seemed to me better to consider one the summit 
and the other the base of a leaf of a species of Magnolia which differs from 
any other in the collection by being much broader and rounder. In form 
and in nervation it strikingly resembles some leaves we might select of 
Magnolia acuminata. 
Locality: Woodbridge.

I have with some hesitation considered the plant represented in the 
figures now given as identical with Heer’s species from the Dakota group 
of Nebraska, the chief difference being that in MW. alternans the leaf is 
wedge-shaped at the base, while in our species from the Amboy Clays 
‘The original manuscript name by which Dr. Newberry designated this species is Magnolia lati- 
folia, n. sp. It is, however, manifestly identical with M. Lacoeana Lesq. (FI. Dak. Gr., p.201, Pl. LX,
