Not forked, the rather short and stout branches without cataphyls, 
dioecious. Internodes rather short (2-4x15-30 mm.), like the foliage be- 
coming nearly glabrous from slightly but not canescently tomentose. 
Leaves oblanceolate to obovate, very obtuse, 1.5-2 or 3 or even 4.5x2-5 cm., 
rather fleshy, obscurely 3- to 5-nerved or also veiny, cuneately subpetioled 
for about 5 mm. Spikes mostly solitary, short (10-15 or rarely 20 mm., 
lengthening to 25-40 mm. in fruit), at first puberulent, with about 4 short 
joints clavately 6-flowered when pistillate and subglobose and about 12- 
flowered when staminate: peduncle 2-6 mm. long: scales more or less 
short-pilose. Fruit white or whitish, globose or somewhat ellipsoidal, 
glabrous, about 4x5 mm., in approximate whorls: sepals nearly or quite 
glabrous, closely inflexed. — Plates 5, 24, 25. 
Atlantic United States, on a great variety of Angiosperms* (Acer, 
Gleditsia, Nyssa, Platanus, Quercus, Ulmus, ete.), of which it most eom- 
monly affects only one in a given region, doubtless illustrating the same 
host-adaptation as the mistletoe of northern Europe, Viscum album, with 
which it was at first confused.—The type to be understood as of Carolina.
