Stipulas very short, rounded, acuminated on both sides, ex Vahl ; 

 but in the specimen collected at Porto-Rico by Ryan, the sti- 

 pulas are connate a little way at the base, and bidentate at the 

 apex ; both are, however, probably the same species.

CLXIII. POLYO'ZUS (from iroXv, poly, many, and ofrf, 

 ozos, a branch ; in reference to the shrub, which is much 

 branched). Lour. coch. p. 74. exclusive of the first specits. D. C. 

 prod. 4. p. 494. Blum, bijdr. p. 947. Polyozus, A. Rich, 

 mem. soc. hist. nat. Par. 5. p. 183. Ixora species, Poir. 



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

 turbinate tube, and an obsoletely denticulated deciduous limb. 

 Corolla with a cylindrical tube, a villous throat, and 4-5 spread- 

 ingly reflexed lobes, which are longer than the tube. Anthers 

 4-5, alternating with the lobes of the corolla, hardly exserted. 

 Style short ; stigma bifid. Ovarium crowned by the disk. 

 Berry drupaceous, nearly globose, 2-celled, naked at the apex ; 

 cells containing 1 pyrena each. Pyrense excavated on the inside, 

 and gibbous on the back, coriaceous, 1 -seeded. Albumen carti- 

 laginous. Embryo minute, erect. Small glabrous trees, natives 

 of Asia and the Mauritius. Leaves opposite. Stipulas inter- 

 petiolar. ' Cymes trichotomous, axillary, and terminal. This 

 genus is nearly allied to Ixora, but differs in the tube being 

 shorter than the corolline lobes, and in the limb of the calyx being 

 deciduous. It is also nearly allied to Baconia, but differs in the 

 stigma being bifid. 



1 P. LANCEOLA'TA (Lour. coch. p. 75.) leaves lanceolate, 

 petiolate ; racemes terminal, compound ; flowers tetramerous 

 and tetrandrous. 1? . G. Native of China, about Canton. 

 Branches diffuse. Flowers reddish. 



Zanceo/a<e-leaved Polyozus. Shrub 4 feet. 



2 P. ACUMINA'TA (Blum, bijdr. p. 948.) leaves oblong-lanceo- 

 late, very much acuminated ; racemes axillary ; flowers tetra- 

 merous and tetrandrous. J? . S. Native of the western part 

 of Java, on the mountains. Branchlets compressed. Stipulas 

 broad, short. Flowers small, corymbose ; corymbs in the axils 

 of the superior leaves on short peduncles. 



Acuminated-\e&\e& Polyozus. Shrub. 



3 P. LATIFO'LIA (Blum, bijdr. p. 948.) leaves elliptic-oblong, 

 acule at both ends ; flowers pentamerous and pentandrous. fj . 

 S. Native of the island of Nusa-Kambanga, near Java. 



Broad-leaved Polyozus. Shrub. 



t Doubtful species. 



4 P. ? MADERASPATA V NA (D. C. prod. 4. p. 495.) leaves pe- 

 tiolate, oblong-lanceolate, hardly acute at the base, and rather 

 acuminated at the apex ; corymbs terminal, trichotomous ; 

 flowers pentamerous and pentandrous. 17 . S. Native of the 

 East Indies, about Madras. Stipulas broad, short, acuminated, 

 adpressed. Leaves coriaceous, those of the flowering branches 

 4 inches long and 1-| broad, standing on petioles about half an 

 inch long. 



Madras Polyozus. Shrub. 



5 P. ? BARBA'TA (Smith, in Rees' cycl. vol. 26. under Pavetla,) 

 leaves lanceolate-oblong, acute, smooth ; panicles brachiate, di- 

 varicate, smooth ; tube of corolla one-half shorter than the 

 lobes, which are 5, and beset with bristles in the mouth. T? . S. 

 Native of the island of Hominoa, in the East Indies. Leaves 

 coriaceous, a foot long, and 2 inches broad. Stigma cylindrical, 

 acute. From the tube of the corolla being shorter than the 

 lobes, and the flowers being pentamerous and pentandrous, it is 

 probably a true species of Polyozus. 



Bearded Polyozus. Shrub.

N. B. P. bipinnulus (Lour. coch. p. 75.) should be excluded 

 from the present order altogether, from the bipinnate leaves, but 

 its true place is unknown.

CLXIV. GRUMl'LEA (from grumula, a little heap; in 

 reference to the albumen, which is grumose). Gaertn. fruct. 1.

LIN. SYST. Pentdndria, Monogynia. Calyx with an ovate 

 tube, and a 5-toothed limb. Corolla, stamens, and style un- 

 known. Berry crowned by the calyx, ovate-globose, rather 

 coriaceous, 2-celled, rarely 3-celled. Seeds solitary in each 

 cell, plano-convex or angular. Albumen rather cartilaginous, 

 grumose from chinks and fissures. Embryo erect, small, rather 

 curved, and nearly dorsal, with lanceolate cotyledons. This 

 genus is hardly known, but from the albumen it comes very near 

 to Rutidea ; and to Psychotria from the form of the fruit. 



1 G. NIGRA (Gaertn. fruct. 1. p. 138. t. 28. f. 2.) berry 

 smooth ; teeth of calyx on the top of the fruit, conniving and 

 rounded. lj . S. Native of Ceylon, where it is called Hogdala. 

 Berries black.

2 G. PSYCHOTRIOIDES (D. C. prod. 4. p. 495.) berry striated 

 lengthwise, crowned by the short tubular truncate limb of the 

 calyx. Ij . S. Native of the western coast of Africa, in Casa- 

 mancia at Itou, where it was collected by Leprieur and Perrottet. 

 Shrub glabrous. Leaves petiolate, elliptic, cuneated at the base, 

 acute at the apex, shining. Stipulas solitary on both sides, lan- 

 ceolate, deciduous. Flowers unknown. Fruit 5-C together at 

 the tops of the branches, sessile, almost capitate, black, ovate, 

 2-celled. Seeds ruminated as in Annbna.

LIN. SYST. Pentandria, Monogynia. Calyx with a globose 

 tube, and a small 5-parted limb : lobes ovate. Corolla funnel- 

 shaped, with a terete tube, which is dilated at the apex, and 5 

 spreading oval lobes. Anthers 5, sessile in the throat of the 

 corolla, exserted, oblong, but shorter than the lobes of the 

 corolla. Style clavate at the apex ; stigmas 2, combined, indi- 

 cated only by a furrow. Berry nearly dry, globose, crowned by 

 the vestiges of the calyx, 1 -celled, 1 -seeded. Seed globose, um- 

 bilicate at the base, wrinkled on the outside. Albumen large, 

 grumose, cartilaginous. Embryo oblique, terete. Shrubs, 

 natives of India and Africa. Branches terete, hispid while young. 

 Leaves opposite, on short petioles, hispid on the nerves and 

 petioles. Stipulas twin on both sides, combined to the middle, 

 subulate at the apex. Spikes racemose, interrupted, terminal ; 

 flowers disposed in almost sessile opposite fascicles. Bracteas 

 and calyxes hispid. Corollas glabrous, becoming black on dry- 

 ing, but probably white in the recent state.

 of leaves on the under surface, rather hispid ; leaves elliptic-ob- 

 long ; spikes terminal, formed of interrupted fascicles of flowers ; 

 fruit glabrous. Tj . S. Native of Sierra Leone, where it was 

 collected by Smeathmann ; and of Casamancia near Itou, where
