 ing; leaves lanceolate, glabrous; petioles geniculated at the 

 base ; racemes rather longer than the leaves, brachiate, pani- 

 cled ; flowers sessile, sub-secund. fj . S. Native of the 

 Mauritius. Said to be allied to P. fce'tida, but is probably a 

 species of Laugeria.

 oblong, pilose beneath and on the branches ; panicles terminal,

Brazilian Paederia. Shrub 3 to 4 feet ? 



Cult. The species of Paederia are free growers, and will 

 thrive in any kind of rich light soil ; and cuttings strike root 

 readily in the same kind of soil, under a hand-glass. 



Tribe IX. 



COFFEA'CEjE (this tribe agrees with the genus Coffea in 

 the fruit being baccate, and in containing 2 hard 1-seeded nuts). 

 D. C. diss. 1806. H. B. et Kunth, nov. gen. amer. 3. p. 352. 

 exclusive of some genera. A. Rich, ex D. C. prod. 4. p. 472. 

 Psychotriaceae and Cephalideae, Cham, et Schlecht. in Linnaea. 

 4. p. 4. and p. 133. Fruit 2-celled (f. 105. h. f. 107. c.), 

 baccate, containing 2 I -seeded bony or crustaceous nuts (f. 107. 

 </.), which are flat inside and usually marked by a furrow on 

 the outside ; rarely containing only 1 nut from abortion. Nuts 

 adhering by the inner sides. Albumen horny. Trees or shrubs. 

 Leaves opposite. Stipulas inter-petiolar, with 2 on each side, 

 which are either combined or distinct. 



SUB-TRIBE I. COFFEE'*: (this sub-tribe contains shrubs agree- 

 ing with the genus Coffea in having distinct flowers). D. C. 

 prod. 4. p. 472 Psychotriaceae, Cham, et Schlecht. 4. p. 4. 

 Flowers distinct, not combined. 



CXL. AMARACA'RPUS (from afiapa, amara, leading 

 water, and (capiroe, karpos, a fruit ; probably in reference to the 

 furrow on the outside of the pyrenae or nuts). Blum, bijdr. 

 p. 954. A. Rich, mem. soc. hist. nat. par. 5. p. 198. D. C. 

 prod. 4. p. 472. 



LIN. SYST. Tetrimdria, Monogy'nia. Calyx with an oval 

 tube and a 4-cleft unequal limb. Corolla funnel-shaped, with 

 a villous throat and a deeply 4-cleft limb. Stamens 4, inserted 

 in the throat of the corolla. Style 1 ; stigma 2-lobed. Drupe 

 baccate, crowned by the calyx, containing 2 bony 1-seeded 

 pyrenas, which are furrowed a little on the back. A small 

 shrub, with downy branchlets. Leaves opposite, on short pe- 

 tioles, lanceolate, glabrous above, paler beneath, and rather 

 downy on the veins. Stipulas connate at the base, bifid at the 

 apex, deciduous. Flowers small, solitary, in the axils of the 

 leaves, rarely terminal, sessile, bracteolate at the base. Habit 

 and axillary inflorescence of this genus disagree with Psy- 

 chdtria.

 Java, and the Island of Nusa-Kambanga.

 quer, aKavOof, acanthos, a spine ; in reference to the strong 

 opposite thorns). Gaertn. fil. carp. 3. p. 18. t. 182. D. C. 

 prod. 4. p. 473. Canthium species, ex Juss. Rich. 



LIN. SYST. Pentdndria, Monogy'nia. Calyx with a globose 

 tube, and a small 5-toothed permanent limb. Corolla, stamens, 

 and style unknown. Berry globose, 2-celled, crowned" by the 

 calyx. Seeds solitary in the cells, and fixed to the bottom of 

 the cells. Albumen cartilaginously fleshy. Embryo very mi- 

 nute, seated in the base of the albumen, with a short inferior 

 radicle An Indian shrub, furnished with opposite spines, but 

 the leaves and flowers are hardly known. This genus is nearly 

 allied to Canthium, but differs in the seeds being fixed to the 

 bottom of the cells, not to their tops, and in the embryo being 

 small. The Spina spinarum of Rumph. amb. cited by Gartner, 

 for this plant has nothing to do with Rubiacece, in the leaves being 

 alternate and serrated, and is therefore referrible to Stigmarbta 

 Janghomas ; but perhaps the Oxycantha Javanica, Rumph. 

 amb. 7. t. 19. f. 3. is a species of Damnacanthus or Canthium.

 tube, a bearded throat, and 4-5 spreading lobes. Anthers 4-5, 

 inserted at the throat, hardly exserted. Style filiform, ex- 

 serted ; stigma undivided, thick, ovate-globose, or mitre-formed. 

 Berry globose, or didymous, fleshy, crowned by the calycine 

 teeth, 2-celled. Seeds solitary in each cell, inserted towards 

 the apex, inverted, incurved. Albumen fleshy. Embryo cen- 

 tral, with a long superior radicle. Asiatic or African shrubs, 

 with spinose or unarmed branches. Leaves opposite, rather 

 coriaceous. Stipulas interpetiolar, solitary'on both sides. Pe- 

 duncles axillary, short, many-flowered.
