1908] Rehder,— New England Species of Psedera 27 
PSEDERA QUINQUEFOLIA var. murorum, n. comb. — Ampelopsis 
latifolia Tausch, Flora 21:738. 1838.— Ampelopsis hederacea var. 
murorum Focke, Abh. Naturw. Ver. Bremen 4:560. 1875. А 
southern form distinguished from the type by its more numerous, 
usually 8 to 12 ramifications of the tendrils and the broader leaflets. 
PsEDERA QUINQUEFOLIA var. minor, n. comb.— Parthenocissus 
radicantissima var. minor Graebner, Gartenfl. 49:286. 1900. This 
is apparently a form of the proceeding variety and differs from it only 
in its smaller and broader, oval to orbicular-ovate, more slender-petio- 
luled leaflets. 
PsEDERA QUINQUEFOLIA var. Saint-Paulii, n. comb.— Partheno- 
cissus Saint-Paulii Graebner, Gartenfl. 49:283. 1900.— Ampelopsis 
Saint-Pauli Mottet, Rev. Hort. 79:567. 1907. А variety occurring 
in Iowa, Illinois, Missouri and Texas; differing from the type in the 
tendrils having 8 to 12 ramifications and in the elliptic to obovate 
leaflets gradually narrowed into a very short petiolule and pubescent 
beneath like the branchlets; it has more than any other variety the 
tendency to form aerial rootlets. 
PSEDERA VITACEA Greene, Leafl. Bot. Observ. 1:220. 1906.— 
Cissus quinquefolia Sims. Bot. Mag. 51: tab. 2443.  1824.— Ampe- 
lopsis hederacea var. dumetorum Focke, Abh. Naturw. Ver. Bremen. 
4:559. 1875.— Quinaria quinquefolia Koehne, Gartenfl. 41: 402. 
1892, not Rafinesque.— Parthenocissus laciniata Small, Fl. S. E. U.S. 
759. 1905. А climbing shrub usually low and rambling over bushes, 
but occasionally climbing high into trees, fastening itself by the twin- 
ing ramifications of the tendrils; branchlets like the leaf-buds green 
while young, distinctly swollen at the joints, branches always without 
aerial rootlets; tendrils with 3 to 5 slender twining ramifications with- 
out disks. Leaves long-petioled, 5- or occasionally 3-foliolate, leaf- 
lets oval to ovate-oblong, acuminate, usually narrowed at the base, 
coarsely serrate or incisely serrate with the teeth often spreading, 
bright or dark green and lustrous above, lighter green and lustrous 
beneath, glabrous or sparingly pubescent on the midrib beneath. 
Coryinbs glabrous, on slender peduncles, opposite to the leaves and 
solitary, distinctly dichotomously branched, with usually elongated 
ramifications, 5 to 7 cm. broad. Berries subglobose, 6 to 8 min. 
thick, bluish black without or with slight bloom; seeds usually 3 or 4, 
with an oval or obovate chalaza. Flowers from the end of June to the 
end of July. Marine: Hartford, J. C. Parlin; Piscataquis River
