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. iSSi. and in 

 young fruit June 4. iSSi, at Sandy Landing, Md. Speci 

 mens 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. sabinaefolium, Spring., = Ly- 



copodium complanatum, L. 



The forms referred to this variety were collected two miles 

 north of Bladensburg, in young fruit, July 20, 1879. anc ^ 

 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, sabincefolium, is distinguished by haying 

 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 flattened, leaves of two forms, 

 imbricated oppressed in 4 ranks. These specimens are 

 certainly anomalous in having the stems creeping under 

 ground, but otherwise they agree well with the type.
