584 RUBIACEjE. CLXVIII (A). RUDGEA. CLXIX. ANTHERURA. CLXX. RONABEA. CLXXI. PSYCHOTRIA. 



Native of the Island of O-Wahu, in forests on the mountains. 

 Branches and branchlets of panicle compressed. 



Mann's Coffee-tree. Shrub 4 to 6 feet. 



Cult. All the species of Coffea thrive well in a mixture of 

 turfy loam, turfy peat, and sand. They require to be watered 

 a good deal, and to have plenty of pot-room to thrive well. Ripe 

 cuttings strike root freely in sand under a hand-glass in a moist 

 heat ; and the young plants so raised, produce flowers and fruit 

 more readily than those raised from seed. As the plants are 

 apt to be infested by insects, particularly the mealy bug, they 

 should be examined often, and the insects rubbed off with a 

 brush, otherwise the plants will look unsightly. 



CLXVIII (A). RU'DGEA (named by Salisbury after Edward 

 Rudge, F. R. and L. S., author of Plantarum Guianse Rariorum, 

 Icones et Descriptiones, 2 vol. fol. London, 1805). Salisb. in

LIN. SYST. Pentandria, Monogynia. Calyx with an ovate- 

 globose tube, and a 5-parted limb ; lobes acute. Corolla with 

 a long slender terete tube, 5 linear spreadingly recurved seg- 

 ments, which are hooked on the back and acute, and a naked 

 throat. Anthers sessile, within the throat, inclosed. Stigma 

 bilamellate. Fruit 2-celled, 2-seeded. Trees or shrubs, natives 

 of Guiana. Branchlets and petioles clothed with cinereous 

 down. Leaves opposite, large, smoothish. Stipulas interpe- 

 tiolar, large, ovate, fringed, deciduous. Panicles terminal, dense, 

 bracteolate, with the branches opposite. Flowers blackish in 

 the dried state, but most probably white in the recent state. 

 Fruit not sufficiently known.

 acuminated; tube of corolla 10 times longer than the lobes of 

 the calyx. ^ . S. Native of French Guiana. Leaves 10 inches 

 long, and about 3 broad. Corolla downy outside. 



Lance-leaved Rudgea. Shrub or tree.

 fj . S. Native of French Guiana. Leaves 4-5 inches broad, and

Oval-leaved Rudgea. Shrub or tree. 



Cult. See Coffea above for culture and propagation. 



CLXIX. ANTHERU'RA (from avOrjpa, anlhera, an anther, 

 and ovpa, oura, a tail ; the anthers end in a long tail each). 

 Lour. coch. p. 144. D. C. prod. 4. p. 503. Psychotria species, 

 Willd. Poir. 



LIN. SYST. Pentandria, Monogynia. All as in Psychotria, 

 but the corolla is rotate and 5-parted ; the anthers sagittate at 

 the base, and furnished with a long reflexed tail at the apex ; 

 the style subulate, and longer than the corolla, and the stigma 

 simple. A glabrous shrub, with reddish diffuse branches. 

 Leaves opposite, ovate-lanceolate, on short petioles. Panicles 

 terminal, erect, loose, racemose. Flowers white, with red fila- 

 ments. Berries ovate, brownish red. Stipulas unknown. 



1 A. RU'BRA (Lour. coch. p. 144.) fy . G. Native of Cochin- 

 china and the Moluccas. Caryophyllaster ruber, and probably 

 C.albus, Rumph. amb. 3. p. 136. Psychotria rubra, Poir. suppl.

 this word). Aubl. guian. 1. p. 154. Lam. ill. t. 166. Juss.

 Willd. 



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

 tube, and a small 5-toothed limb. Corolla oblong, rather funnel- 

 shaped, with 5 spreading acute lobes, and a naked throat. An- 

 thers 5, oblong, inclosed. Stigma bilamellate. Berry ovate, um- 

 bilicate, containing 2 1-seeded nuts, which are flat inside, and 

 convex outside. Glabrous shrubs, natives of Guiana. Leaves 

 oval, acute, on short petioles. Stipulas solitary on both sides. 

 Peduncles axillary, 2-6-flowered, shorter than the petioles. 

 Flowers small, white. Bracteoles 2 under each flower. Allied 

 to Psycholria, but differs in the berries not being ribbed. Per- 

 haps the species of Psychotria with axillary peduncles ought to 

 be joined to this genus. 



1 R. LATIFOHA (Aubl. guian. 1. p. 155. t. 59.)stems flexuous; 

 leaves ovate, ending in a short point, variegated with green and 

 blue above. Jj . S. Native of Guiana, in woods at Oj ac-Orapu 

 and Sinemari. Psychotria axillaris var. a, Willd. spec. 1. p. 

 962. Stems simple, nodose, twisted. Stipulas broad, acute. 

 Flowers white. Lobes of corolla pilose. Berries black. 



Broad-leaved Ronabea. Shrub 2 to 3 feet. 



2 R. ERE'CTA (Aubl. guian. 1. p. 156.) stems erect; leaves 

 ovate, acute, thin, greenish-yellow. Tj . S. Native of Guiana, 

 in woods along with the preceding. R. latifolia ft, Gmel. syst. 

 1. p. 365. Psychotria axillaris |8, Willd. spec. 1. p. 962. Leaves 

 4 inches long and 1-j broad. Flowers white. Berries black. 



Erect Ronabea. Shrub 1 to 2 feet. 



3 R. ? MYODE'NDRON (A. Rich, in mem. soc. hist. nat. 5. p. 

 270.) leaves linear-lanceolate, very acute, petiolate ; flowers 

 disposed in few-flowered terminal corymbs ; fruit didymous, 

 hardly umbilicate. Ij . S. Native of Brazil, where it is called 

 Herbo do rato. Flowers white. 



Rat-tree Ronabea. Shrub. 



4 R.? MORINDOIDES (A. Rich. 1. c.) leaves elliptic, acumi- 

 nated, petiolate ; flowers small, crowded into many terminal 

 pedunculate pea-formed heads ; fruit pea-formed, rather umbili- 

 cate at the apex ; seeds chinky outside. Pj . S. Native of French 

 Guiana. Flowers white. 



Morinda-like Ronabea. Shrub. 



5 ? R. ? DIDYMOCA'RPOS (A. Rich. 1. c.) leaves elliptic, acumi- 

 nated, on short petioles; Stipulas connate intrapetiolar trun- 

 cate, furnished each with 2 bristles; flowers disposed in a ter- 

 minal cyme ; fruit didymous, umbilicated by a terminal dot. f; . 

 S. Native of French Guiana. This and the two preceding 

 are very doubtful species of Ronabea, from the flowers being 

 terminal, and ought perhaps on that account to be joined with 

 Psychotria. 



Tniin-fruited Ronabea. Shrub. 



Cult. For culture and propagation see Coffea above.
