CXLV. M ARQUrSI A (evidently called so after some person 

 of the name of Marquis, who is unknown to us). A. Rich. mem. 

 soc. hist. nat. Par. 5. p. 192. D. C. prod. 4. p. 477. Canthium 

 species, Labill. 



LIN. SYST. Pentdndria, Monogy'nia. Calyx with an ovate 

 tube, and a short acutely 5-parted limb. Corolla with a short 

 tube, a glabrous throat, and 5 oblong spreading bluntish lobes, 

 which are longer than the tube. Anthers 5, ovate, sessile at 

 the throat of the corolla. Style filiform, length of tube ; stigmas 

 4-6. Berry ovate, fleshy, 2-celled, crowned by the calyx. Seed 

 or pyrense solitary in the cells, erect, convex on the outside, but 

 flat and furrowed inside. A glabrous shrub, with spinose 

 branches. Leaves on short petioles, opposite, lanceolate, small, 

 attenuated at both ends. Stipulas small, solitary on both sides, 

 adhering to the petioles. Pedicels axillary, solitary, 1-flowered, 

 deflexed, calyculated by 4 small combined bracteas under the 

 flower. Flowers small. This genus differs from Canthium in 

 the stigma being divided into many lobes, and in the seeds rising 

 from the bottom of the cells, not from the top.

 Diemen's Land. Canthium quadrifidurn, Labill. nov. holl. 1. p. 

 69. t. 94. A very spinose shrub, very variable in habit, having 

 the branches sometimes loose and elongated, and sometimes short 

 and crowded. Pedicels rising each from a sheath. 



La Billardier's Marquisia. Shrub 5 to 6 feet. 



Cult. For culture and propagation see Chiococca, p. 569. 



CXLVI. NESCI'DIA (from nescio, to be ignorant; the fruit 

 being unknown the genus is very doubtful). A. Rich. mem. soc. 

 hist. nat. Par. 5. p. 192. D. C. prod. 4. p. 477. 



LIN. SYST. Pentdndria, Mi.nogy'nia. Limb of calyx hardly 

 any, quite entire. Corolla with a short tube, a naked throat, 

 and a 5-cleft limb ; segments incumbent, bluntish. Stamens 5, 

 inserted in the throat, almost sessile, inclosed. Anthers linear, 

 acute. Style short ; stigmas 2, linear, acute, joined face to face. 

 Ovarium 2-celled; ovula solitary in the cells, fixed to the mid- 

 dle dissepiment. Seeds unknown. A glabrous shrub, native of 

 the Mauritius. Leaves opposite, petiolate, like those of a 

 myrtle, coriaceous, scarcely acute. Stipulas short, interpetiolar. 

 Flowers axillary, solitary, girded by a bidentate calyculous at 

 the base This is a doubtful genus from the fruit being un- 

 known, but it has the habit of Myonvna. 



1 N. MYRTIFO'LIA (A. Rich. 1. c.) Tj . S. Native of the 

 Mauritius. 



Myrtle-leaved Nescidia. Shrub 5 to 6 feet.

 and (mopa, spora, a seed ; in reference to the cells of the fruit 

 being 2-seeded). D. C. prod. 4. p. 477. Canthium species, 

 Lindl. 



LIN. SYST. Tetrdndria, Monogy'nia. Calyx with an obovate 

 tube, a very short subcampanulate 4-toothed limb. Corolla 



with a wide tube, which is shorter than the lobes, a pilose throat, 

 and 4 ovate fleshy spreading lobes. Anthers 4, sessile at the 

 throat, semi- exserted. Style length of the tube; stigma bifid. 

 Ovarium 2-celled ; cells 2-seeded ; ovula collateral, ascending. 

 Fruit and seeds unknown. A glabrous shrub, native of China, 

 with tetragonal branches. Leaves opposite, petiolate, oblong- 

 lanceolate, acuminated at both ends. Stipulas solitary on both 

 sides, ovate, acuminated, permanent. Flowers axillary, crowded, 

 almost sessile, yellowish-green, calyculate by combined bracteas 

 at the base. This genus agrees with Epithinia in the cells of the 

 ovarium being biovulate, but differs in the ovula being col- 

 lateral, not one on the top of the other.

 shore). Jack, in mal. misc. 1. no. 2. p. 12. D. C. prod. 4. 

 p. 477. 



LIN. SYST. Tetrandria, Monogy'nia. Limb of calyx cylin- 

 drical, scarcely 4-toothed, permanent. Corolla tubular, with a 

 4-parted spreading acute limb, and a villous throat. Stamens 

 4, exserted ; anthers linear. Style exserted ; stigma bifid. 

 Berry 8-furrowed, containing 2 oblong 2-seeded pyrenae. Seeds 

 placed one above another. An Indian shrub. Leaves oppo- 

 site, petiolate, obovate, smooth, almost veinless. Stipulas want- 

 ing? Peduncles axillary, dichotomous, many flowered, with a 

 solitary flower in the fork. Flowers white. This genus is said 

 to be allied to Malanea, but differs in the cells of the fruit being 

 2-seeded, and from all other Rubiaceous plants in the want of 

 stipulas.

 brous throat, and 4 oval roundish bluntish spreading lobes.

 serted, one-half shorter than the lobes of the corolla. Style

 bose, naked at the apex, 2-celled, 2-seeded. Seeds convex on

 las solitary on both sides, apiculated by a short point. Peduncles 

 axillary, trifid or trichotomous. Flowers rose coloured on the
