NORTH AMERICAN FLORA 



(Volume 25 



Leaflets 8-10 cm. broad. 



Petals 12 mm. long, 2 mm. broad; panicle branched 



from the base. 

 Petals 3.5-7 mm. long, 1-1.5 mm. broad. 



Flowering inflorescence sessile, the branches 

 short, of about equal length; petals 6-7 mm. 

 long, strigillose; ovary raised on a short 

 gynophore. 

 Flowering inflorescence branched from or above 

 the base, the branches very unequal in length ; 

 petals 3.5 mm. long, glabrous; ovary sessile. 

 Leaflets with the secondary veins obscure, the primary slender, 

 vanishing far from the margin ; leaflets not bearded in the 

 axils beneath; calyx apparently deciduous after the falling of 

 the petals; petals densely strigillose. (Lesser Antilles and 

 continental tropical America.) 

 Ovary pilose or tomentose, the hairs usually persistent on the 

 capsule; leaflets apparently not bearded in the axils of the 

 veins beneath except in no. 16. 

 Flowers small, the petals 3-7.5 mm. long; ovary mostly 4-celled. 

 Twigs, petioles, rachis, and branches of the inflorescence 

 clothed with a dense ferruginous tomentum. 

 Capsule nearly glabrous, with few scattered appressed 

 hairs above near the apex; leaflets bearded in the axils 

 of the veins beneath. 

 Capsule densely clothed with a persistently velvety 

 tomentum; leaflets densely tomentose beneath. 

 Twigs, petioles, rachis, and branches of the inflorescence not 

 densely tomentose. often somewhat pubescent. 

 Inflorescence branching at or from near the base, the 



branches about equal in length. 

 Inflorescence paniculate, sometimes raceme-like or spike- 

 like, the branches unequal in length. 

 leaflets sessile or nearly so, loosely hispid-pilose on 

 the midrib and primary veins beneath ; calyx, petals, 

 and ovary setose-pilose; petals 3-3.5 mm. long. 

 Leaflets usually petioluled, glabrous, puberulent or 

 with spreading hairs on the veins beneath ; 

 petals and ovary pubescent or puberulent with 

 appressed hairs; petals 5-7.5 mm. long. 

 Leaflets 4—6, mostly of an obovate type, cuneate 



at the base; panicle axillary, 5 cm. long. 

 Leaflets mostly of an oblong, elliptic, or ovate 

 type, rarely somewhat obovate. 

 Leaflets 6-20, commonly 10 or more; panicles 



up to 23 cm. high. 

 Leaflets 4-8; inflorescence short, raceme-like 

 or spike-like. 

 Leaves less than 2 dm. long; inflorescence 

 borne in the axils of leaves or twigs of 

 the season; petals nearly glabrous; leaflets 

 ciliate, acuminate. 

 Leaves more than 2 dm. long; inflorescence 

 borne on branches of the preceding year; 

 petals puberulent; leaflets abruptly short- 

 Flowers large, the petals 9-13.5 mm. long (unknown in nos. 28 

 and 29) ; ovary 4- or 5-celled. 

 Leaflets 4-12. 



Panicles often long and slender, raceme-like or spike-like, 

 above the branched base. 

 Flowers distinctly stalked, the pedicels often equaling 

 or longer than the stipe-like base of the calyx. 

 (Lesser Antilles.) 

 Flowers sessile or very short-stalked, the pedicels often 

 inconspicuous and shorter than the stipe-like 

 base of the calyx. (Continental tropical Amer- 

 ica.) 

 Panicle-branches minutely puberulent. 

 Panicle-branches hirsute. 

 Panicles open, with spreading branches of nearly equal 

 length. 

 Leaflets elliptic-ovate or elliptic, 12-17 cm. long. 

 Leaflets oblong or oblong-elliptic, the upper 20-25 cm. 

 or more long; fruit a 4- or 5-celled woody capsule. 

 Leaflets about 30, 26-29 cm. long, 8-9.5 cm. broad; flowers 

 unknown; fruiting panicle 8 cm. high; capsule 5-celled. 

 Ovary 10-celledj densely hirsute; calyx-lobes and petals 5.
