The leaves resemble in almost every respect those which I collected from the tree now standing in the Bartram estate, Philadelphia, south of the mansion, and which is said to have grown from an acorn of the

original Bartram Oak planted by the discoverer.” Prof. Ward.

VI. SPECIES EXCLUDED.

172 Vitis vulpina, L., Vitis riparia, Michx.

The specimens mentioned in the "Flora” that were referred to

this species, were collected in flower May 22. 1881, and in young fruit June 4, 1881, at Sandy Landing, Md. Specimens in mature fruit collected Sept. 12, 1885, on the rocks below Chain Bridge. From characters furnished by the seeds and the diaphrams separating the nodes of the stem, as pointed out by Dr. Engelmann, this is referred to the V. riparia, Michx.

220. Lespedeza violacea, Pers.,= L. reticulata, Pers.

This species has been compared at the Gray Herb. by Mr.

Walter Deane, and referred as above. 973. Juncus marginatus, var. bifloms, Engl., Juncus marginatus,

Rostk.
Compared at the Gray Herbarium by Mr. Walter Deane who

pronounces this to be the type and not the variety. 1251. Lycopodium complanatum, L., var. sabinæfolium, Spring., = Ly

copodium complanatum, L.
The forms referred to this variety were collected two miles

north of Bladensburg, in young fruit, July 20, 1879, and
at Clifton Station, Va., Oct. 12, 1884, by Prof. Ward.
These have been submitted to Prof. L. W. Underwood,
of Syracuse University, and he pronounces them all to
be complanatum. This variety, or, as it has been lately
known, species, sabinefolium, is distinguished by having
the stems leafy to base of spikes, or nearly so, elongated, .
creeping, usually underground; branches erect, short, di-

chotomous; leaves 4-rowed, apparently terete. In complanatum the stems are fattened, leaves of two forms,

imbricated-oppressed in 4 ranks. These specimens are certainly anomalous in having the stems creeping underground, but otherwise they agree well with the type.
