 equilateral obtuse undulate blades narrowed into winged petioles ; stem-leaves smaller, 

 with pinnatifid or pinnately parted acute blades with entire or incised lobes or segments : 

 pedicels spreading, 1-3 cm. long: calyx becoming nearly 2 cm. long ; lobes linear or broad- 

 ened upward, toothed or incised, about equalling tbe corolla-tube : corolla orange, 2-3 cm. 

 long ; lobes ovate or oblong-ovate : capsules fully 1 cm. long.

30. AFZiJLIA J. F. Gmel. 



Annual, caulescent, much branched herbs. Leaves opposite, relatively small : blades 



1-2-pinnately parted or dissected. Flowers solitary in the axils of more or less leaf-like 



bracts, manifestly pedicelled. Calyx of 5 sepals united into a campanulate tube at the 



base, the lobes generally longer than the tube. Corolla mainly yellow, rotate-campanulate, 



the lobes nearly equal, longer than the tube, not dilated at the base. Stamens 4, nearly 



equal, conspicuously exerted : filaments glabrous or sparingly pubescent : anthers sagittate, 



longer than the filaments ; sacs distinct. Style filiform, long-exserted : stigma minute. 



Capsule flattened at the acute or acuminate apex. \_Seymeria Pursh.] 



Segments of the leaf-blades filiform or subulate : corolla glabrous without. 1. A. casfioides. 

 Segments of the leaf-blades linear or broader : corolla pubescent or glandular without. 



Corolla pubescent without : pedicels mostly over 5 mm. long. 2. A. pextiirata. 



Corolla glandular without : pedicels mostly less than 5 mm. long. 3. A. Texana. 



1. Afzelia cassioides (Walt.) J. F. Gmel. Stems minutely pubescent, 5-12 dm. 

 tall, widely branched. Leaves very numerous ; blades pinnately 1-2 -dissected into subu- 

 late or filiform segments : pedicels slender, 3-6 mm. long : calyx-lobes glabrous, subulate, 

 1-1.0 mm. long : corolla glabrous Avithout ; limb barely 1 cm. broad, the lobes oblong or 

 nearly so : filaments glabrous or merely puberulent below : capsules 5-6 mm. long, 

 glabrous, the flattened tip fully j as long as the globular base. \_Seymeria tenuiJoUa Pursh.] 



In low grounds or pine lands, North Carolina to Florida and Texas. Summer and fall. 



2. Afzelia pectinkta (Pursh) Kuntze. Stems copiously viscid-pubescent, 2-5 dm. 

 tall, rather widely branched. Leaves numerous ; blades pinnately parted or pinnatifid to 

 entire above, the segments linear or oblong : pedicels 5-10 mm. long: calyx-lobes pubes- 

 cent, linear, 2-3 mm. long : corolla pubescent without ; limb about 1 cm. broad, the lobes 

 mostly oval or suborbicular : filaments pubescent : capsules hispidulous, 5-6 mm. long, 

 the flattened apex less than h, as long as the broadly ovoid base. 



In dry sandy soil. North Carolina to Florida and Alabama. Summer and fall. 



3. Afzelia Texana (A. Gray) Small. Stems 4-10 dm. tall, widely branched, 

 densely pubescent, at least above, with viscid-glandular hairs. Leaves relatively few ; 

 blades mostly 2-pinnatifid, the lower sometimes 3-pinnatitid and the upper often merely
