 3 to 4 feet. 



2 A. PEDCNCULA'RIS (D. C.

Peduncular Adina. Fl. July, Aug. Clt.? Shrub. 



Cult. The culture and propagation of the species of Adina 

 are the same as those of Nauclea, p. 469, but do not require 

 so much heat. 



IV. BREO'NIA (this name is not explained, but is perhaps so 

 called after some botanist of the name of Breon). A. Rich. mem. 

 soc. hist. nat. par. 5. p. 290. D. C. prod. 4. p. 620. 



LIN. SYST. Pentdiidria, Monogynia. Calyx with a 5-parted 

 limb, and truncate sub-cuneated lobes. Corolla with a terete 

 tube, and a flat, spreading, 5-lobed limb : having the lobes oval- 

 lanceolate. Stamens half exserted, inserted in the throat of the 

 corolla. Style very long, exserted ; stigma bipartite, with the 

 lobes approximate. Ovarium 2-celled ; cells 7-8-ovulate ; ovu- 

 las fixed to the membranous placentas, which hang from the axis. 

 Fruit somewhat crustaceous, indehiscent. A tree. Leaves 

 opposite, very large. Stipulas connate. Flowers disposed in 

 axillary, solitary, globose heads, which stand on long peduncles ; 

 each peduncle girded by a beaked involucrum, which at length 

 bursts on one side and falls off". This genus is nearly allied to 

 Nauclea, but probably referrible to Sarcocephalece, by the fruit 

 being indehiscent.

 Madagascar.

 under the head of flowers). Jack, mal. misc. vol. 2. ex Wall.

LIN. SYST. Pentandria, Monogynia. Limb of calyx cam- 

 panulate, dilated, coloured, divided irregularly. Corolla with a 

 short tube, and a 5-lobed limb, which is valvate in aestivation. 

 Anthers large, inserted in the tube of the corolla. Style bifid ; 

 stigmas linear, thick. Ovarium 2-celled ; cells many-seeded ; 

 placentas semi-cylindrical or convex, central. The rest un- 

 known. A radicant shrub, with tetragonal stems, with 2 of the 

 angles more prominent than the other 2. Leaves opposite, on 

 short petioles. Stipulas ligulate. Flowers pale red, disposed 

 in terminal, dense, globular heads ; each head involucrated by 

 a salver-shaped involucrum. This genus is nearly allied to 

 Nauclea. 



1 L. ERUBE'SCENS (Jack, 1. c.). T? . S. Native of Singapore. 

 Leaves on short petioles, ovate-lanceolate, acute at both ends, 

 about 8 inches long. The involucrum which surrounds each 



head of flowers is entire and cup-shaped. Flowers sessile. 

 Ovarium crowned by a prominent nectareal ring.

LIN. SYST. Pentandria, Monogynia. Calyx with a sub- 

 globose tube, girded at the base by an unequally 4-lobed invo- 

 lucel; limb biparted, deciduous: having acute lobes. Corolla 

 salver-shaped, with a short tube and a spreading bluntly 6-7- 

 parted limb. Anthers 6-7, sessile in the throat of the tube. 

 Stigma bilamellate. Capsule globose, areolate at the apex, and 

 pubescent in the areolae, 2-celled, containing 2 cocculi, which 

 are separable from the calyx : one of them only dehiscent. 

 Placentas central, connecting the margins of the valves. Seeds 

 minute, numerous, oval, winged a little, rather pubescent 

 at the apex. Embryo straight in the fleshy albumen : having 

 the radicle turned towards thehylum. A much branched shrub, 

 native of St. Domingo ; having the branches clothed with resin. 

 Leaves oval, white beneath, finely reticulated. Stipulas joined 

 into a short sheath. Flowers axillary, solitary, white, on short 

 pedicels, girded by 4 concrete bracteas, forming a kind of invo- 

 lucel to each flower.

LIN. SYST. Hexdndria, Monogynia. Calyx with a turbinately 

 oblong tube, and a 6-parted limb : having the segments subu- 

 late. Corolla large, funnel-shaped, with a short tube, an obco- 

 nical ventricose throat, and a bluntly 6-lobed limb. Stamens 

 inserted at the bottom of the throat ; anthers linear, much ex- 

 serted. Stigma furrowed. Capsule coriaceously chartaceous, 

 obovate, compressed, 2-celled ; valves bifid at the apex. Pla- 

 centas spongy, at length nearly free. Seeds compressed, erect, 

 girded by a membranous margin. Embryo long, in fleshy 

 albumen : having a centripetal radicle, and flat cotyledons. 

 South American trees. Leaves ovate, acuminated, on short 

 petioles ; Stipulas broad, short, acute. Peduncles usually trifid, 

 axillary, and terminal. Flowers white, sometimes septamerous. 

 This genus comes very near to Portlandia.
