AEQUATORIALES QUADRANGULAEES 109 



lar or 4-winged. Cataphyls a single pair toward the base, spreading. 

 Leaves narrowly obovate to elliptical-oblong, more or less mucronately 

 very obtuse, 1-1.5x3.5-5 or 6 cm., cuneately subpetioled for scarcely 3 mm. 

 Spikes more or less clustered, moderate (30-40 mm.), with 3-5 slender 

 elongated joints rather turbinately some 12- to even 26-flowered in 4 or 

 4+2 series : peduncle 2-3 or rarely 5 mm. long, sometimes followed by a 

 sterile joint. Fruit white, subglobose, cellular-papillate, 3 mm. in diam- 

 eter: sepals closely inflexed. Plates 154, 155. 



Andean region. The type from Colombia. 



Specimens examined: COLOMBIA, (Bonpland, 1795 on Guazuma, 

 the type of L. quadrang ularis ). Without locality (Holton, 656). ECUA- 

 DOR. Quito (Haenke, the type of V. salicifoUum). Guayaz (Sodiro, Aug. 

 23,1872). Bodega (Sodiro, Sept. 3, 1872). Hacienda El Recreo, Man- 

 abi (Eggers, 14829). 



As in the case of P. rubrum, the authors of the binomial here used 

 had in mind a different species from the one to which it is now applied, 

 but their intention to transfer Loranthus quadrangularis HBK. into 

 PJioradendron is unmistakable. The Colombian type differs from the 

 PJcuadoran salicifoUum in having more rhombic internodes.

More or less pseudodichotomous, the rather long branches with basal 

 cataphyls only, androgynous. Internodes rather short (2-3x30-50 mm.), 

 nearly smooth, acutely quadrangular. Cataphyls a single nearly basal 

 pair. Leaves obliquely obovate, obtuse, 1.5-2x3.5-5 cm., rather abruptly 

 subpetioled for over 5 mm. Spikes more or less clustered, moderate 

 (30 mm.), with about 3 slender elongated joints some 8-flowered in 4 or 

 4+2 series : peduncle about 2 mm. long. Fruit subglobose, smooth, 3 mm. 

 in diameter : sepals closely inflexed. Plate 155.

Phoradendron Wiesnerianum n. sp. 



Somewhat pseudodichotomous, the rather long branches with basal 

 cataphyls only, androgynous. Internodes moderate (2-3x30-50 mm.), 

 smooth, rhombically quadrangular or 4-winged. Cataphyls a single pair 

 toward the base, blunt and spreading. Leaves subspatulately elliptical, 

 mucronately very obtuse, 1-1.5x4-5 cm., cuneately subsessile. Spikes
