29. MACRANTHERA Torn 



Perennial caulescent herbs, glabrous below the inflorescence, blackening in drying. 

 Leaves opposite : blades pinnatifid or pinnately parted. Flowers in 1 -sided racemes. 

 Calyx erect, of 5 partially united sepals : lobes entire or incised. Corolla yellow or orange : 

 tube cylindric, elongated, barely dilated at the throat : lobes 5, oblique, spreading. 

 Stamens 4, exserted : filaments nearly equal : anther-sacs parallel. Stigma clavate. C'ap- 

 sule short, loculicidally dehiscent. 



Calyx-lobes entire : corolla-tube much longer than the calyx. 1. M. LeContn.

1. Macrantbera LeContei Torr. Stems 5-12 dm. tall, puberulent or minutely 

 glandular-pubescent, simple or sparingly branched. Stem-leaves with pinnatifid short- 

 petioled blades 4-9 cm. long: pedicels spreading or declined, 1-2.5 cm. long: calyx 9-13 

 mm. long; tube broadly campanulate ; lobes subulate or linear-subulate, entire, much sur- 

 passed by the corolla-tube : corolla yellow or orange-yellow, 2 cm. long ; lobes oblong 

 or oblong-ovate : capsules ovoid, about 1 cm. long. 



In pine lands, Georgia, Alabama and Florida. Summer and fall. 



2. Macranthera fuchsioides Torr. Stems 6-15 dm. tall, often sparingly branched, 

 glabrate or minutely glandular. Basal leaves clustered, with oblong-ovate or oblong in- 

 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 the corolla-tube : corolla orange, 2-3 cm. 

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



In damp pine lands, Georgia, Alabama and Florid'a. Fall. 



30. AFZELIA 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. cassioides. 

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



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



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



1. Afzelia cassioides (Walt.) J. F. Gmel. Steins 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, 

 1-1.5 mm. long: corolla glabrous without ; 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 as long as the globular base. [Seymeria tenuifolia Pursh.] 



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



2. Afzelia pectinata (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 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-pinnatifid and the upper often merely
