the base is sometimes rounded and sometimes wedge-shaped. I doubt if the 
latter character can be insisted upon as a characteristic feature of M. alter- 
nans. In other respects the leaves are essentially identical. The middle 
nerve is strong and persistent, lateral nerves fie, generally alternating and 
forming a continuous and marked festoon parallel with the margin.

MaGNouta GLAUCOIDES Newb. n. sp. 
Pl. LVI, figs. 1-4. 
Leaves elliptical, 10 to 12° in length by 4°™ to 5™ in width, long 
petioled, rounded at summit, slightly wedge-shaped at base, margins entire; 
nervation delicate or sunk in the integument of the leaf, midrib strong, 
lateral nerves numerous, fine, leaving the midrib at an acute angle, uniting 
to form a festoon near the margin. 
It would be difficult for anyone to discover any marked difference 
between these leaves and those of the common Magnolia virginiana L. 
(M. glauca). The petiole is perhaps longer, but this is a variable character 
in the living species, and yet we should hardly be warranted in consid- 
ering this as identical with the common plant of our Atlantic States. 
Possibly in the future the fruit and foliage may be found so fully repre- 
sented that it may be possible to establish the identity; at present it seems 
better to indicate by the specific name the close resemblance between them..

MaGNouia woopBRIDGENSIS Hollick n. sp.t 
In PO@O.Ovd ie tikes abke Je IMU iikes, Gets 
Leaves 12 to 18 in length by 5 to 8" in greatest breadth, long- 
ovate in outline, broadest near base, rounded below, blunt-pointed at 
summit, margins entire; nervation delicate. 
These leaves have somewhat the form of those of J. longifolia, but are 
much smaller, more wedge-shaped, broadest near the base, rapidly drawn 
into a narrow but obtuse summit. 
‘In Dr. Newherry’s manuscript this species is named Magnolia cuneata, but as he had already 
given that name to a fossil plant from the Cretaceous of Orcas Island (Geol. Rept. of the Exploration 
of the Yellowstone and Missouri rivers, 1869, p. 163), it became necessary to change it, and it was 
accordingly named for the locality at which it was collected.—A. H.
