Part 5, 1924] POLYGALACEAE 371 



Racemes in axillary clusters of 1-3, subsessile, 1-1.8 cm. long; upper petals 



densely ciliate to middle; wings 5-5.2 mm. wide; ovary glabrous. 1. E. Micheliana.

 upper petals glabrous on margin or only sparsely ciliate; wings 5.8-9.5 

 mm. wide; ovary pubescent at least on wing. 

 Leaves oval, rather thin, not or only slightly reticulate; wing of fruit at base 

 as broad as or broader than the fruiting cell. 

 leaves 2-6 cm. long; petioles 3-9 mm. long; pedicels 8-13 mm. long; 



ovary densely strigillose; wing of fruit 9-1 1 mm. wide at base. 2. E. Brownii. 



Leaves 7-21 mm. long: petioles 1-1.5 mm. long; pedicels 4—7 mm. long; 

 ovary densely pubescent on wing; wing of fruit 4-7 mm. wide at 

 base. 

 Leaves emarginate, not at all reticulate, strigillose beneath; fruiting 



cell narrowly margined above. 3. E. virgata. 



Leaves rounded or obtuse, distinctly reticulate, pilosulous beneath; 



fruiting cell narrowly but distinctly winged above. 4. E. elliptica. 



Leaves ovate to elliptic or rarely oval, thickish, reticulate; wing of fruit 

 usually narrower at base than the fruiting cell. 

 Leaves strigillose to sparsely pubescent or pilose beneath. 



Pedicels strigillose; upper petals glabrous or sparsely ciliate toward 



apex; keel ciliate toward base of saccate portion. 5. E. diversifolia. 



Pedicels densely pubescent with incurved hairs; upper petals pubes- 

 cent within at base; keel ciliolate and pubescent within toward 

 base of saccate portion. 6. E. Lamarckii. 



Leaves densely and softly pilosulous or pilose beneath; pedicels densely 

 spreading- or ascending-pilosulous. 

 Wings glabrous except for the ciliate margin ; sepals sparsely spreading- 

 pilosulous on back ; fruiting cell narrowly winged on \ipper margin, 

 the wing prolonged into a triangular free tooth. 7. E. sylvestris. 



Wings pubescent on claw and down middle of back, ciliate; sepals 

 densely pilose except near margin; fruiting cell obscurely margined 

 on upper edge, the margin obliquely decurrent into the proper wing. 8. E. coriacea.

 above dark-green, sparsely strigillose or glabrate, prominulous-reticulate, beneath glaucescent, 

 densely strigillose; petioles 4-6 mm. long; racemes simple, 1-1.8 cm. long; bracts ovate, 

 deciduous, 1 mm. long; pedicels strigillose, 4-5 mm. long; flowers probably rosy or purplish; 

 sepals oval to suborbicular-oval, obtuse, 2-2. S mm. long; wings broadly oval, 8 mm. long, 

 5-5.2 mm. wide, rounded, ciliate except on the cuneate claw, about 9-nerved; keel ciliate about 

 to middle on saccate portion, 7-8 mm. long; staminal tube ciliate about to middle; ovary 

 obliquely oval, winged below, glabrous; fruit unknown. 



Type locality: Atirro, Cartago, Costa Rica, at an altitude of 610 meters.
