[Vol. vin, Art. 120 



powerfully clawed subpendant rachises; petiole about 3 feet 

 long, compressed, 2 to 3 inches wide, smooth and yel- 

 lowish on the upper shallowly concave surface, spinescent 

 along the edges on the sides especially toward the base, 

 convex beneath; rachis smooth on both sides except the 

 hooks on the nether side toward the distal end, its upper 

 edges spinescent below the middle; leaflets hanging or 

 rather descending, more or less concave on the lower 

 side toward the base, bright green on both sides and 

 with scattered setae-like bristles, the midvein conspicuous 

 on the upper surface, not rigid but quite tough; old 

 infrutescence ascending from the leaf axils, the distal 

 part much recurved, 5 feet in length; the branches 

 ascendingly curved, alternate, 3 to 5 inches apart, the 

 basal ones larger, all similarly rebranched; spathels green, 

 covered with a yellowish brown pulverulence.

Field-note: — A looping lofty tree climber; old stem 

 smooth, hard, green, 0.75 inch thick, the sheathed portion 

 2.5 inches through; leaves alternatingly scattered along 

 the upper one third of the length of the stem, basal 

 portion ascending but otherwise recurved, 6 feet long; pet- 

 iole 1 foot in length, flat on the upper side, convex 

 below, 1 inch across the base, more spinescent beneath; 

 leaflets strongly recurved, shining on both sides, some- 

 what paler green beneath, the margins more or less 

 subinvolute, chartaceous;flagellum 25 feet long, arising sub- 

 opposite the leaves, roundly flattened toward the base, 

 terete otherwise, provided with especially stout hooks 

 along the lower side except toward the base, strongly 

 recurved and pendant or drooping; old persistent in- 

 florescence similarly disposed and upon equally long stalks 

 from nearly opposite the leaves; the hanging branches 

 bearing the spikes nearly smooth, about 3 feet apart; 

 the basal one arising 10 feet from the base of the ra-
