1£6 THE GENUS PHORADENDRON 
Seareely forked, drying golden yellow, the long thick branches with 
eataphyls on all joints, dioecious. Internodes long (3-8x100-125 mm.), 
granular, somewhat hexagonally flattened, dilated below the nodes. Cata- 
phyls a single pair, about 10 mm. above the base, deltoid, keeled and 
pointed. Leaves elliptical-ovate, more or less mucronately obtuse to 
emarginate, 4x9 to 10x15 em., euneately wing-petioled for 10 mm. Spikes 
solitary, very long (60 to over 100 mm.), with about 4 thiek cylindrical 
joints often over 100-flowered in about 8 (6-10) series: pedunele gran- 
ular, 5-10 mm. long. Fruit (immature) elongated, nearly smooth, 3x5 
mm.: sepals closely inflexed.— Plate 235. 
Andean region (? exclusively) on Aralia.— The type from Peru. 
Specimens examined :—PrRv. Catani, between Sandia and Chunchus- 
mayo (Weberbauer, 1288, July 25, 1902,—the type). Cucharo (Poep- 
pig, 1829-30, in the Vienna herbarium). 
IV. DIcHOTOMAE. 
Normally forking at every node, the branches therefore not percur- 
rent though sometimes ending in a flower-spike. 
Leaves basinerved. 
Venulose above, obscurely nerved beneath. HUALLAGENSES. 
Equally nerved and veiny on both sides, or opaque. 
Small. GARDNERIANAE. 
Moderate or large. 
Coriaceous or moderately thin. 
With terminal spikes in the forks. CYMOSAE. 
Not eymose. P. Jenmam. 
Very large and thick, dimidiate. P. obliquum. 
Leaves penninerved. 
Thick and flat. 
Obscurely nerved. P. Northropiae. 
Evanescently heavy-nerved. P. Eggersü. 
Chartaceous, veiny, often revolute. P. racemosum. 
54. HUALLAGENSES. 
: Leaves moderate, acuminately ovate-lanceolate, drying rather thin 
with the lower surface smooth but heavily basinerved and the upper re- 
tieulately veiny and more or less venulose. Shoots terete. Cataphyls 
typically a single pair, nearly basal on all joints,—the branches being 
sometimes pereurrent, and sometimes cymosely dichotomous, and rarely 
without eataphyls on some joints. Flowers in 2 or4 series. Fruit ovoid, 
rather rough, with nearly closed sepals. South America. 
Spikes short (20-30 mm.), with short joints. P. huallagense. 
Spikes long (50 mm.), with long joints. P. laxiflorum.
