RUBIACEJi. XXXIII. OXYANTHUS. XXXIV. STYLOCORYNA. 



Cult. For culture and propagation see Oxyanthus below. 

 All the species are very pretty when in flower. 



XXXIII. OXYA'NTHUS (from ofrc, oxys, sharp, and 

 avdos, anthos, a flower ; in reference to the acute teeth of the 

 calyx and acuminated segments of the corolla). D. C. ann. 

 rnus. !). p. 218. Juss. mem. mus. 6. p. 390. D. C. prod. 4. 

 p. 376. Lindl. coll. p. 13. 



LIN. SYST. Pentdndria, Monogynia. Calyx with an obo- 

 vate tube (f. 92. a.), and a short, acutely 5-toothed limb (f. 92. 

 .). Corolla with a very long tube (f. 92. c.), a glabrous 

 throat, and a 5-parted regular limb (f. 92. rf.) : having the seg- 

 ments oblong and acuminated. Stamens 5, rising from the 

 throat of the corolla, free, exserted (f. 92. 6.). Anthers very 

 acute. Style filiform, clavate at the apex (f. 92. e.~), protruding 

 beyond the a: thers. Fruit 2-celled, and probably baccate. 

 Shrubs, natives of Guinea. Leaves elliptic, acuminated, on 

 short petioles. Stipulas oblong-triangular, falling off but slowly. 

 Peduncles axillary, racemosely corymbose. This genus comes 

 very near Posoqueria, but differs from that genus in the limb of 

 the corolla being regular, in the throat being glabrous, and its 

 parts being acute, and in the clavate stigma. 



1 O. SPECIOSUS (D. C. 1. c. and in diss. ined. with a figure) 

 branchlets, leaves, and calyxes quite glabrous ; calycine teeth 

 very much acuminated ; racemes many-flowered ; tube of co- 

 rolla one half shorter than the leaves. Tj . S. Native of Sierra 

 Leone on the mountains, where it was collected by Smeathmann. 

 Flowers about 20 in each raceme, apparently red, according to 

 the dried specimens, but are probably white or milk-coloured in 

 their recent state. 



Showy Oxyanthus. Shrub 3 to 4 feet. 



FIG. 92. 



2 O. TUBIFLO'RUS (D. C. prod. 

 4. p. 376.) branchlets, leaves, 

 and calyxes glabrous ; calycine 

 teeth bluntish ; racemes very 

 short, 3 -flowered ; tube of co- 

 rolla longer than the leaves. 

 I? . S. Native of Sierra Leone 

 on the mountains. Gardenia 

 tubiflora, Andr. bot. rep. t. 183. 

 O. speciosus, Ait. hort. kew. 

 ed. 2. vol. 1. p. 371. but not 

 of D. C. Flowers by threes, 

 white, 6 inches long, sweet 

 scented. 



Tube-Jlonered Oxyanthus. Fl. 

 July. Clt. 1789. Sh. 3 to 4 ft. 



3 O. HiRsi/Ttis (D. C. prod. 



4. p. 376.) branchlets, petioles, and nerves of leaves on the 

 under side as well as the calyxes beset with hairy down ; caly- 

 cine teeth acute ; racemes few-flowered ; tube of corolla much 

 longer than the leaves. T? . S. Native of Sierra Leone, on 

 the mountains. O. speciosus, Sims. bot. mag. t. 1992. Lindl. 

 coll. t. 13. but the synonymes given are extremely doubtful, 

 and ought probably to be excluded. Ucriana racemosa, Schum. 

 pi. guin. p. 107. Tube of corolla 6 inches long. Flowers 

 white, sweet-scented, (fig. 92.) 



Hairy Oxyanthus. Fl. July. Clt. 1789. Shrub 2 to 3 ft. 



4 O. VILLO'SUS ; villous all over ; leaves petiolate, obovate, 

 acute ; flowers subcapitate, terminal ; tube of corolla very long ; 

 style much exserted ; stigma clavate. f? . S. Native of Sierra 

 Leone. Flowers cream-coloured, very fragrant. Calyx 5-cleft. 



Villous Oxyanthus. Shrub 2 to 3 feet. 



Cult. This genus is easily distinguished by its very long, 

 slender, sweet-scented flowers. All the species thrive well in 

 a mixture of loam, sand, and peat; and cuttings are easily 



rooted by planting them in a pot of sand, and placing it under 

 a hand-glass, in heat. 



XXXIV. STYLOCORY'NA (from <rnAoc, stylos, a style, 

 and Kopvvi), coryne, a club ; in allusion to the stigma, which is 

 clavate). Cav. icon. 4. p. 45. t. 368. Gaertn. fil. carp. 3. p.
