LIN. SYST. Decdndria, Monogynia. Tube of calyx oblong- 

 ovate, more or less hispid, and usually bracteate ; lobes 5, 

 subulate. Petals 5, obovate. Stamens 10. Anthers equal, 

 each furnished with a very short connective, which is biauricu- 

 lated behind. Ovarium glabrous above, and as if it were trun- 

 cate. Style filiform ; stigma capitate. Capsule baccate, 5- 

 celled. Seeds ovate, angular. American subshrubs, hispid 

 from thick pili. Branches from compressed to terete. Leaves 

 on short petioles, those opposite each other of unequal size, the

 ders usually confluent. Flowers solitary or few in the axils of 

 the leaves. 



1 M. GUIANE'NSIS (Aubl. guian. 1. p. 443. t. 176.) branches 

 and petioles beset with spreading bristles ; leaves on short pe- 

 tioles, of unequal size, the larger ones ovate, acuminated, some- 

 what denticulated, 5-nerved, obtuse at the base, bearing a 

 bladder at the base of the limb, the smaller ones oblong, with- 

 out any bladder ; flowers axillary, solitary, on short pedicels ;

2 M. HYPOPHY'SICA (D. C. prod. 3. p. 166.) branches and 

 petioles beset with a few spreading bristles ; leaves of unequal 

 size, on short petioles, the larger ones oval, acuminated, some- 

 what serrulated, 5-nerved, obtuse at the base, bearing a bladder 

 at the base of the limb, the smaller ones oval-oblong, acumin- 

 ated, without any bladder ; flowers axillary, numerous, almost 

 sessile ; teeth of calyx short, subulate ; bracteas 4, broad, each 

 ending in a short acumen. fj . S. Native of Brazil, in woods. 

 Melastoma Maieta and M. hypophysicum, Schrank et Mart, 

 mss. Very near M. Guianensis, but differs in the branches 

 being more compressed and less bristly, but the calyxes are 

 more bristly and teeth shorter. 



Under-bladder-leaved Maieta. Shrub 2 to 3 feet. 



3 M. HETEROPHY'LLA (D. C. 1. c.) branches and petioles his- 

 pid from spreading bristles ; leaves of unequal size, the larger 

 ones petiolate, bearing 2 bladders at the top of the petiole, oval- 

 oblong, acuminated, the smaller leaves sessile, cordate, and 

 stem-clasping, nearly orbicular, mucronate, not bladdery ; cymes 

 axillary, pedunculate, few- flowered. Pj . S. Native of Peru.

LII. CALO'PHYSA (KQ\OS, kalos, pretty, and ipvcra, physa, 

 a bladder ; in reference to stipular bladders at the base of the 

 petioles). D. C. prod. 3. p. 166. 



LIN. SYST. Octdndria, Monogynia. Tube of calyx oblong, 

 enlarging with the fruit, and roundish, and therefore bottle- 

 shaped ; lobes 4, broad, short, plutnosely ciliated from bristles. 

 Petals 4, obovate. Stamens 8 ; filaments flat, tapering to the 

 apex. Anthers oblong, without auricles. Style filiform, not 

 capitate at the apex. Capsule baccate, 4-celled. Seeds ovate, 

 angular ? A Brazilian shrub, allied to Tococa, but differs in the 

 bladders not being at the apex of the petiole but at the base, 

 apparently in place of stipulas, in the parts of the flowers being 

 quaternary, not quinary, in the calyx being at length bottle- 



shaped, in the anthers being without auricles, and in the stigma 

 not being dilated. 



1 C. TOCOCOI'DEA (D. C. 1. c.). Tj . S. Native of Brazil, in 

 shady places. Branches terete, and are as well as the petioles 

 beset with spreading, stiff bristles. Bladders roundish, one on 

 each side at the base of the petiole. Leaves cordate, acute, 

 7-nerved, toothed, ciliated, beset with scattered bristles above, 

 and with bristles on the nerves beneath, but glandular between 

 the nerves. Cymes few-flowered, axillary, crowded, short. 



Tococa'like Calophysa. Shrub. 



Cult. See Meldstoma for culture and propagation, p. 764.

 cula/a in the Khassee language). Roxb. fl. ind. 1. p. 180. Wall, 

 pi. asiat. rar. 2. t. 2. Blume in bot. zeit. 1831. no. 27. p. 489. 



LIN. SYST. Tridndria, Monogynia. Tube of calyx oblong 

 or somewhat trigonal, usually muricated, adhering to the ova- 

 rium ; limb trifid, with the segments deciduous. Petals 3, 

 ovate-lanceolate, acute. Stamens 3. Anthers linear-oblong, 

 straightish, emarginate at the base, opening by 2 pores at the 

 apex, without any appendages. Ovarium truncate at the apex, 

 glabrous. Style filiform ; stigma obtuse. Capsule turbinate, 

 crowned by the margin of the calyx, which is thickened on the 

 inside, 3-celled, 3-valved, valves opening only at the apex. 

 Seeds cuneate, angular, of 2 forms. Usually small shrubs, 

 rarely annual plants. Branches terete. Leaves opposite, rarely 

 scattered, those opposite each other are for the most part un- 

 equal in size, one of which is sometimes almost abortive, quite 

 entire or toothed, membranous, hairy. Peduncles axillary and 

 terminal, racemose or fasciculate, few or many-flowered. Flowers 

 rose-coloured. The ternary number of the parts of the flower 

 is sufficient to distinguish this genus from all others of Me- 

 lastomacece.

 p. 490. Calyx hairy, hardly angular. Petals ovate, acute, broad

1 S. BEGONMFOLIA (Blum. 1. c.) stem herbaceous, hairy; 

 leaves quintuple or septuple-nerved, obliquely cordate at the 

 base, acute, quite entire, ciliated, scabrous above, but beset with 

 small adpressed bristles beneath, those opposite each other

 racemes axillary and terminal, many-flowered ; flowers sessile.

 Bantam. Flowers rose-coloured.

 nervules, oblong, acuminated, auriculately semi-cordate at the

 tains. Flowers rose-coloured.
