Phoradendrum carneum Urban, Bot. Jahrb. vol. 23. Beiblatt 5. p. 1. 
1897. 
Somewhat pseudodichotomous, the moderate branches with basal cata- 
phyls only, dioecious?. Internodes rather short (2-4x30-60 mm.), resin- 
ous-dotted like the foliage, ancipital becoming terete. Cataphyls a single 
pair, basal, somewhat tubular and white-margined. Leaves linear- 
lanceolate, obtuse or mucronate to acute, .5-1.2x5-15 em., rather evidently 
3- or occasionally 5-nerved but scarcely veiny, euneately narrowed for 
5 to 10 mm. rather than petioled. Spikes mostly clustered, moderate 
(20-30 mm.), smooth, with about 3 oblong joints some 8-flowered in 4 
series when pistillate: peduncle 2-5 mm. long, bearing a few flowers when 
elongated : scales and receptacular cups short-ciliate. Fruit globose, red- 
dish-orange, 4-5 mm. in diameter, somewhat verrucose: sepals inflexed 
and nearly or quite meeting. —Plate 69.

Somewhat pseudodichotomous, the moderately long slender branches 
with basal cataphyls only, dioecious. Internodes short (2x15-30 mm.),
