PITTIER — PLANTS EEOM COLOMBIA AND CENTRAL AMERICA. 119 



blades 14 to 18 cm. long, 14 to 16 cm. broad; basal sinus about 4 cm. deep and 5 cm. 

 broad; lateral lobes broadly auriculate and more or less triangular-acuminate; middle 

 lobe ovate-lanceolate, acuminate, narrower at the base; venation conspicuous on both 

 sides, the lateral main nerves bifurcate and at first contiguous to the margin of the 

 einus. Tendrils rather slender. 



Flowers middle-sized. Peduncles of the male inflorescence stout, more or less 

 eulcate in dry specimens, smooth, 20 to 24 cm. long, and bearing a short spike of 

 5 to 15 sessile flowers. Tube of the calyx subcylindrieal, slightly ventricose at the 

 base, 10 to 12 mm. long, 3 mm. broad; teeth 

 triangular, slightly contracted near the tip, 1 

 mm. long. Petals obovate, obtuse at the apex, 

 sparsely papillose, red, 6 to 7 mm. long. Anthers 

 linear, scarcely shorter than the tube of the calyx 

 and about 1 mm. thick; appendage barely 0.3 

 mm. long, obtuse and not papillose. 



Female flowers and fruits not known. 



Colombia: Around Rio Frio, between the 

 Cienega de Santa Marta and the foothills (State 

 of Magdalena), altitude about 100 meters, Pittier 

 1630, male flowers, July 4, 1906 (U. S. National 

 Herbarium no. 6000G6). 



On account of its straight anthers with glabrous 

 appendage, and its subspicate male inflorescence, 

 this species should take place near A. warscewiczii 

 Hook, and A. pallida Cogn., only that it differs 

 from both by its simple 3-lobate leaves. By the 

 coincidence of two of the above characters, viz, 

 the glabrous appendage and 3-lobate leaves, our 

 plant constitutes a new feature in the genus Angu- 

 ria and along with the sessile flowers and the 

 general glabrescence, these characters give suffi- 

 cient ground for describing it as a new species.

Anguria limonensis Pittier, sp. nov. Figure 25. 



Stems slender, eulcate or angulose-striate, glabrous. 



Leaves 3-foliolate. Petioles 3 to 4 cm. long, rather thick, subcanaliculate, pubes- 

 cent; petiolules 5 to 10 mm. long. Leaflets ovate to lanceolate, more or less attenuate 

 at the base, acuminate at the tips, glabrous, dark green above, paler beneath; nerva- 

 tion pinnate, scarcely prominent below; margin entire or obscurely sinuate; middle 

 leaflet 8 to 15 cm. long, about 4 cm. broad, the lateral ones smaller, often asymmetrical 

 and sublobate. Tendrils strong, terete, smooth. 



Male flowers small, sessile or subsessile. Common peduncle 10 to 25 cm. long, 

 deeply sulcate, bearing a short spike of 20 to 25 flowers. Calyx 8 to 10 mm. long, 

 green, cylindrical and scarcely ventricose at the base, striate; teeth spreading, more 

 or less subulate, 0.5 to 1 mm. long. Petals red, ovate, very briefly unguiculate, 

 obtuse at the tip, hairy-papillose on both faces, 4 to 6 mm. long, 2 to 3 mm. broad. 

 Stamens inserted on the tube of the calyx at the upper end of their lower half, linear, 

 7 to 9 mm. long, 1 mm. thick, with a very short (0.3 mm.), rounded, papillose append- 

 age. Female flowers and fruits unknown. 



Costa Rica: Along the Caribbean coast between Port Limon and Moiu, Pittier, 

 male flowers only, September, 1899 (Instituto fis.-geogr. Costa Rica no. 16112). 



This species is nearly related to Anguria triphylla Miquel, from which it differs 

 mainly by the dimensions and a few other characters of the male flowers.
