Part 5, 1924] POLYGALACEAE 373 



ovate or oval, 3.S-12 cm. long, 2.2-5.7 cm. wide, obtuse to subacuminate, at base rounded to 

 euneate, pergamentaceous or chartaeeous, thickish or rarely thinnish, above deep-green, some- 

 what lucid, strigillose or puberulous, reticulate with 6-10 pairs of lateral veins, even the tertiary 

 veins prominulous, beneath paler green or glaucescent, similarly pubescent, the hairs along the 

 eosta usually spreading; leaves of the flowering branchlets much smaller and usually oval; 

 petioles strigillose or puberulous, 2-7 mm. long; peduncles 4-10 mm. long; racemes rather 

 loose, rarely branched, the axis densely strigillose or incurved-puberulous, usually 6-14 cm. 

 long; bracts lanceolate to ovate, acuminate, deciduous or rarely persistent, 1.5-7 mm. long; 

 pedicels strigillose, 4-7 mm. long; flowers pink to purplish, the keel with more or less yellow; 

 sepals broadly oval, ciliate, pubescent along midline, 2.5-3.8 mm. long; wings suborbicular 

 to oval-ovate, emarginate, ciliate to middle except on the short claw, 8.3-11.8 mm. long, 6-8 

 mm. wide; keel 8-8.8 mm. long; samara greenish or straw-color, puberulous, 4-6 cm. long; 

 fruiting cell plump, elevated-reticulate, 5-8 mm. long, wing-margined on upper side, the margin 

 1-2.5 mm. wide, prolonged beyond the fruiting cell and connate with the proper wing, usually 

 with a triangular free tooth at apex; wing obovate, narrower at base than fruiting cell, 3.2-5 

 cm. long, 3-4 mm. wide at base (excluding the connate upper wing-margin of fruiting cell), 

 1 1-17 mm. wide near middle. 



Type locality: Tropical America. 



Distribution: Tamaulipas and Michoacan (or Guerrero) to Ecuador; Lesser Antilles, from 

 St. Thomas and St. Croix to South America.

High-climbing shrub; branchlets appressed- or ascending-pubescent, glabrate; leaves 

 ovate or oval-ovate, 2.7-5.2 cm. long, 1.2-3.4 cm. wide, short-pointed or acute but the apex 

 obtuse, at base broadly rounded, reticulate both sides with 4-6 pairs of lateral veins, above 

 dark-green, somewhat lucid, evenly pubescent or pilose with ascending or spreading hairs, 

 beneath paler, more densely pubescent, the hairs along the costa always spreading; petioles 

 1.2-2.5 mm. long; peduncles 5-9 mm. long; racemes rather loose, sometimes branched at base, 

 0.8-7 cm. long; bracts lanceolate, deciduous, 1mm. long; pedicels densely incurved-pubescent, 

 5-6 mm. long; flowers rosy; sepals oval to suborbicular, ciliate and pubescent on midline, 

 2-3.2 mm. long; wings suborbicular-oval, emarginate, 8-8.2 mm. long, 6.2-7.8 mm. wide, 

 ciliate or ciliolate except on claw, 1 0- 1 2-nerved ; keel ciliolate and somewhat pubescent within 

 toward base of saccate portion, 6.S-8.2 mm. long; immature samara 2.4—3.7 cm. long, shortly 

 spreading-pubescent; stipe obsolete; fruiting cell reticulate, narrowly wing-margined on upper, 

 side, 5 mm. long, the margin obliquely decurrent into the proper wing or sometimes prolonged 

 into a short triangular lobe, extending 2 mm. beyond fruiting cell; wing obovate, 2-3 cm. long,
