RUBIACE^E. XL. MENESTORIA. XLI. HELOSPORA. XLII. HIPPOTIS. XLIII. POMATIUM. 



dissepiment. Seeds numerous, wingless, nestling on the super- 

 ficies of the placentas. A much-branched, unarmed, glabrous 

 shrub or small tree, but there are small permanent spurs, 

 which look like spines. Leaves opposite, oval-oblong or ovate, 

 acuminated, on short petioles. Stipulas twin on each side, small, 

 acute. Flowers 3-4 together at the tops of the branchlets, pe- 

 dicellate, and disposed in something like racemes, white, about 

 the size of those of Vinca rbsea, and very similar to those of 

 Gardenia and Randia. 



1 H. JASMINIFL6RA (D. C. prod. 4. p. 390.). Tj . S. Native 

 of Sierra Leone, where it was collected by Smeathmann, Afze- 

 lius, and G. Don. The plant we have seen at Sierra Leone has 

 numerous 1-flowered, terminal, and axillary pedicels ; the tube 

 of the corolla clothed with yellow hairs ; and the segments of 

 the corolla hispid. The shrub bears nothing like spurs or spines 

 that we recollect. 



Jasmine-flowered He'msia. Fl. Feb. Clt. 1824. Sh. 5 to 8 ft. 



Cult. See Gardenia, p. 499. for culture and propagation. A 

 beautiful shrub, clothed with numerous white flowers. 



XL. MENESTORIA (Menestor was a physiologist cited 

 by Theophrastus). D. C. prod. 4. p. 390. 



LIN. SYST. Pentdndria, Monogynia. Calyx wilh a globose 

 tube, a 5-parted limb : and linear, almost subulate, acute, distant 

 segments. Corolla with a long terete tube, 5 oval acute short 

 lobes, and an almost naked throat. Anthers 5, oblong, sessile 

 within the tube of the corolla. Style filiform; stigma bifid, 

 inclosed : lobes linear. Ovarium 2-celled ; placentas many- 

 seeded, adnate to the dissepiment. Fruit baccate, almost dry, 

 areolate at the apex, never crowned, from the lobes of the calyx 

 being deciduous. Seeds very small, wingless. Unarmed shrubs, 

 natives of Nipaul. Leaves opposite. Stipulas solitary on each 

 side, at length deciduous. Corymbs of flowers terminal. This 

 is rather a doubtful genus, differing from Mussce'nda in the tube 

 of the calyx or ovarium being globose, not turbinate, and in the 

 Stipulas being solitary on each side, not twin ; and from Tocoyena 

 in the limb of the calyx being parted to the base.

 beneath, and beset with adpressed villi along the nerves. Ij . 

 G. Native of Nipaul. Branches terete. Stipulas broad, short, 

 very blunt, membranous. Corymbs terminal, trichotomous, on 

 short peduncles ; pedicels puberulous. Corolla 15 lines long, 

 puberulous on the outside ; segments ciliated, apiculated, clothed 

 with adpressed down on the outside, as well as the tube. Style 

 about equal in length to the tube of the corolla ; stigmas 2, 

 linear, applied to each other in the dried state. 



Tocoyena-like Menestoria. Shrub 5 to 6 feet. 



2 M. HAME'LLI* (D. C. 1. c.) leaves oval, acuminated at 

 both ends, on long petioles, rather scabrous from scattered hairs 

 above, and along the nerves underneath. Tj . G. Native of 

 Nipaul. Branchlets compressed. Leaves along with the pe- 

 tioles an inch and more in length. Stipulas ovate, broad, short, 

 acutish. Peduncles numerous, spreading, disposed in loose 

 cymes, rising from the top of the stem and forks of the branches. 

 Corolla 6 lines long, scarcely puberulous. Style very short, in- 

 closed, hardly attaining the height of the anthers. 



Hamellia-like Menestoria. Shrub 5 to 6 feet. 



3 M. MUSSJE'ND^E (D. C. 1. c.) leaves ovate, acute, on short 

 petioles, pale beneath, and downy on both surfaces ; petioles, 

 Stipulas and middle nerve of the leaves clothed with rufous 

 hairs. T? . G. Native of Nipaul. Branches rather hispid and 

 rufous. Stipulas ovate. Corymbs dichotomous, with some of 

 the flowers sessile and solitary in the forks, and others terminal. 

 Calyx hispid ; lobes deciduous. Berry ovate-globose, smoothish. 



Mussanda-like Menestoria. Shrub 5 to 6 feet. 



4 M. ? R!GIDA (D. C. 1. c.) leaves cuneated, retuse, and mu- 

 cronulate, glabrous ; Stipulas ovate, acute. J? . G. Native of 

 Nipaul, at Suembu. Gardenia rigida, Hamilt. ex D. Don, prod,

 ments of the calyx subulate. Limb of corolla 5-lobed; lobes 

 attenuated at the apex.

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

 tetragonal tube, and a somewhat campanulate 4-toothed, erect, 

 permanent limb. Corolla tubular, much longer than the calycine 

 limb, with a naked throat, and 4 oblong spreading lobes, which 

 are valvate in aestivation. Anthers 4, linear, inclosed. Style 

 4-furrowed, and 4-cleft at the apex ; stigmas short, spreading. 

 Berry crowned by the calyx, tetragonal, not divided into cells 

 inside, but bearing the seeds disposed crosswise, in 4 double 

 series, immersed in pulp. Seeds linear, curved a little. A 

 smoothish shrub. Leaves opposite, on short petioles, ovate- 

 lanceolate. Stipulas deciduous, bearing a row of ciliae inside. 

 Peduncles axillary, 1-flowered, shorter than the leaves. Brac- 

 teoles 2, .under each ovarium. This genus is perhaps allied to 

 Gttettdrda or Gardenia.
