2. BOURRERIA P. Br. 
Shrubs or small trees. Leaves alternate or whorled: stipules wanting. Flowers in 
terminal corymbose cymes, numerous or rarely solitary. Calyx-pedicelled : tube campan- 
ulate, persistent and sometimes slightly accrescent: lobes 2-5. Corolla campanulate or in- 
fundibuliform : tube variable in length: lobes 5. Stamens as many as the corolla-lobes, 
adnate to the corolla-tube. Filaments filiform. Ovary 2-celled (incompletely 4-celled), 
sessile in a thin annular disk: styles united to near the apex, sometimes enlarged upward : 
stigmas somewhat flattened. Drupe subglobose, tipped with the base of the style, the 
exocarp thin-fleshy, the 4 bony nutlets each furnished with a ridged appendage on the 
back. Seeds curved, terete, with a brown membranous testa. Endosperm fleshy. 
Leaf-blades very scabrous above; petioles less than 5 mm. long. 1. B. Radula. 
Leaf-blades smooth above ; petioles over 10 mm. long. 2. B. Havanensts. 
1. Bourreria Rádula (Poir.) G. Don. Shrub or small tree sometimes 13 m. tall, 
with finely pubescent twigs and very scabro-pubescent upper leaf-surfaces. Leaf-blades

revolute, short-petioled : corymbs few-flowered, 2-6 cm. broad: pedicels sparingly pubes- 
cent or glabrous in age: calyx campanulate, 6-7 mm. long; lobes oblong to ovate- or 
lanceolate-oblong, shorter than the tube: corolla white, 1 cm. long ; tube funnelform, sur- 
passing the calyx ; limb 1-1.2 em. broad ; lobes orbicular-reniform : fruit subglobose, 9-14 
mm. in diameter. 
In sand, Florida Keys. Also in the West Indies. 
2. Bourreria Havanénsis (L.) Miers. A shrub or tree sometimes 12 m. tall, with 
glabrous foliage. Leaf-blades firm, obovate to oblong- or oval-obovate, 4-12 cm. long, 
rounded or notched at the apex, lustrous above, narrowly or broadly cuneate ; petioles 
11-15 mm. long: corymbs 2-10 cm. broad : pedicels 2-10 mm. long: calyx campanulate, 
5-6 mm. long; lobes triangular-ovate to rounded, shorter than the tube: corolla creamy 
white, about 2 cm. long ; tube slightly longer than the calyx ; limb barely 2 mm. broad, 
lobes suborbicular or orbicular-obovate : fruits subglobose, 10-13 mm. in diameter, orange. 
In sand, Florida Keys. Also in the Bahamas and the West Indies. 
3. BHRETIA P. Br. 
Shrubs or trees. Leaves alternate: stipules wanting. Flowers small, in corymbose 
or paniculate cymes. Calyx campanulate, persistent: lobes 5. Corolla white: lobes 5, 
spreading. Stamens 5, adnate to the corolla-tube : filaments filiform-subulate: anther-sacs 
spreading below. Ovary 1-celled or incompletely 4-celled by the development of 2 parietal 
placentae, in an annular disk : styles 2, filiform, partially united : stigmas depressed-capi- 
tate or clavate. Drupe berry-like, seated in the persistent calyx, with a dry or juicy exo- 
carp and bony 2-seeded nutlets. Seeds curved, terete, with a brown membranous testa.
