Phoradendron vernicosum Greenman, Publ. Field Columb. Mus., Botany 

 vol. 2. p. 250. 1897. 



Scarcely forked, the moderately long branches with basal cataphyls 

 only, dioecious. Internodes rather short and thick (2-4x20-40 mm.) , min- 

 utely papillate, varnished when young, elliptically dilated rather than 

 compressed below the nodes. Cataphyls a single pair toward the base, 

 short-annular. Leaves subelliptical or obovate varying into lanceolate, 

 very obtuse, 1-2x2.5-4 cm., cuneately subpetioled for scarcely 5 mm. 

 Spikes often clustered, short (10-15, lengthening to 20 mm.), with 3 or 4 

 short oblong joints decussately 2-flowered when pistillate: peduncle 1-2 

 mm. long, sometimes with a second pair of scales. Fruit ovoid, somewhat 

 rugulose-warty, 4x5 mm. : sepals closely inflexed. Plate 130.

 on the basal joint only. Pistillate flowers in 2 or 4 series. Fruit round 

 or ovoid, mostly wrinkled, with suberect parted sepals. West Indies.

 Phoradendrum Fid Urban, Symbolae Antillanae. vol. 5. p. 333. 1907. 



More or less pseudodichotomous, the rather long branches with basal 

 cataphyls only, dioecious?. Internodes short (2-3x20 mm.), transversely 

 wrinkled in drying, ancipitally compressed and somewhat dilated up- 

 wards. Cataphyls a nearly basal pair, usually followed at a short dis- 

 tance by a second or a third pair, truncately annular. Leaves falcately 

 rather broadly lanceolate, obtuse, 1.5-2.5 or even 3x5-9 cm., cuneately 

 subpetioled for about 10 mm. Spikes solitary, moderate (scarcely 30 mm. 

 long), with about 3 slender joints 2- to 6-flowered: peduncle some 5 mm.
