84 THE GENUS PHORADENDRON 



PHOBADENDRON LONGIPETIOLATUM (Urban). 



Phoradendrum longipetiolatum Urban, Bot. Jahrb. vol. 23. Beibl. 57. p. 

 6. 1897. 



Scarcely forked, the elongated branches with basal cataphyls only, 

 androgynous. Internodes rather long (2-5x50-70 mm.), smooth, the up- 

 per compressed rather than ancipital. Cataphyls usually a nearly basal 

 pair followed by a second some 5 mm. higher, tubular-bifid, white-mar- 

 gined, exceptionally floriferous like the spike-scales. Leaves falcately 

 narrowly lanceolate to oblanceolate, somewhat mucronately very obtuse, 

 1.5-3x5-10 cm., cuneately attenuate at base for 10-20 mm. Spikes often 

 clustered, short (15-20 mm.), with about 3 short joints some 20-flowered 

 in 6 series: peduncle 3 mm. long: scales evanescently ciliate. Fruit (im- 

 mature) subglobose, smooth. Plate 111. 



Venezuelan region. The type from Venezuela. 



Specimens examined: VENEZUELA. Tovar (Fendler, 1762, the 

 type). 



PHORADENDRON BILINEATUM (Urban). 



Phoradendrum bUineatum Urban, Bot. Jahrb. vol. 23. Beibl. 57. p. 5. 

 1897. 



More or less pseudodichotomous, the elongated branches with basal 

 cataphyls only, androgynous?. Internodes rather long (2-4x50-60 mm.), 

 smooth, the upper somewhat ancipital, with 2 rather persistent keels. 

 Cataphyls a single nearly basal pair, scarcely tubular, sometimes sub- 

 tending spikes. Leaves falcately lanceolate, subacute and often mucro- 

 nate, 2-3.5x9-11 cm., cuneately petioled for 10-15 mm. Spikes mostly sol- 

 itary, moderate (30 mm.), .with about 3 joints some 20-flowered in 4+2 

 series : peduncle 3 mm. long : scales scarcely ciliate. Fruit subglobose, 3 

 mm. in diameter, nearly smooth : sepals suberect. Plate 112. 



Venezuelan region. The type from Venezuela. 



Specimens examined: VENEZUELA. Tovar (Fendler, 1811, the 

 type). 



PHORADENDRON RIGIDUM (Urban). 

 Phoradendrum rigidum Urban, Bot. Jahrb. vol. 23. Beibl. 57. p. 7. 1897. 



Scarcely forked, the elongated branches with basal cataphyls only, 

 androgynous. Internodes rather long (3-5x40-70 mm.), smooth, the up- 

 per ancipital and dilated below the nodes. Cataphyls usually 2, or some- 

 times 3 or 4 pairs, the lowermost shortly above the base, the others at 

 increasing intervals of 10-30 mm., tubular-bifid, white-margined, some- 

 times fertile. Leaves elliptical-obovate, submucronately very obtuse. 

 3x6-8 cm., cuneately contracted for about 5 mm. rather than petioled,
