A fine tree of this species was discovered near Convalescent Camp, Virginia, June 29, 1884, by Prof. Ward. In fine fruiting condition, October 5, 1884. The affinities of this specimen with Q. Phellos are closer than in any of the forms hitherto found. 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."

"I visited this spot in company with Mr. Miller on June 4, 1884, and found the plant nearly extinct. It had died down and withered away without fruiting. On September 28, 1884.

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. 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. sabinæ folium, Spring., Lycopodium 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, sabinæfolium, is distinguished by having the stems leafy to base of spikes, or nearly so, elongated,. creeping, usually underground; branches erect, short, dichotomous; leaves 4-rowed, apparently terete. In complanatum the stems are flattened, 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. |
