70 mm.), resinous-dotted, acutely quadrangular, somewhat rhombically 

 compressed above. Cataphyls a nearly basal pair, annular. Leaves ob- 

 lanceolate to obovate-spatulate, mucronately obtuse, 1-1.5x3-5 cm., cu- 

 neately subsessile. Spikes more or less clustered, moderate (15-25 mm.), 

 with about 3 somewhat clavate or fusiform rather short joints some 10- 

 flowered in 4-4-2 series : peduncle 1-2 mm. long. Fruit yellow, ellipsoid, 

 nearly smooth, about 3x4 mm. ; sepals erect, parted. Plates 9, 150. 



Venezuelan region. The type from Venezuela. 



Specimens examined: VENEZUELA. Caracas (Zuloaga, 1915, the 

 type). 



In the region of P. venezuelense, which it resembles closely but from 

 which it differs in its more spatulate leaves and especially in its ellipsoid 

 fruit with parted sepals. 



Phoradendron commutatum n. sp. 



Phoradendron quadr angular e and P. rubrum of most writers, as to con- 

 tinental North America. 



More or less pseudodichotomous, the moderate branches with basal 

 cataphyls only, androgynous. Internodes moderate (2-3x30-40 mm.), 

 resinous-dotted, acutely quadrangular. Cataphyls a nearly basal pair, 

 sometimes with a second pair at a distance of about 5 mm. Leaves ob- 

 laiiceolate-oblong or obovate, mucronately obtuse to acute, .5-1x3.5-4 cm., 

 or as much as 2x5 cm., cuneately sessile. Spikes mostly solitary, mod- 

 erate (15, becoming 30 mm.), with 3 or 4 slender somewhat fusiform 

 elongated joints some 6-flowered in 4-J-2 series: peduncle about 4 mm. 

 long, often followed by an elongated sterile joint. Fruit red, globose, 

 microscopically cellular-papillate, 3 mm. in diameter : sepals inflexed but 

 not meeting. Plates 150, 151.
