 above, but villous beneath as well as the calyxes and peduncles ; 

 peduncles trifid, 3-flowered. Jj . S. Native of South America, 

 about the Caraccas, where it was collected by Vargas, who says

 half smaller than those of C. speciosa, and the capsule is less 

 compressed, and ribless.

LIN. SYST. Tetra-Hexandria, Monogynia. Calyx with an ob- 

 ovate tube, girded by a 2-4-leaved involucel at the base ; limb 

 2-4-parted: segments narrow, acute, permanent. Corolla with 

 a long terete tube, a short ventricose throat, and a 4-6-parted 

 limb (f. 85. 6.), with spreading flat oval lobes. Stamens 4-6, 

 sessile beneath the mouth of the tube, inclosed (f. 85. c.). 

 Stigma thick, bifid (f. 85. d.). Capsule elongated, 2-celled, 

 crowned by the limb of the calyx ; cells dehiscing from the top 

 inside. Placentas 2, central. Seeds imbricated downwards, 

 rather compressed, ending each in a pencil-formed tail (f. 85. e.}. 

 Embryo straight, in sparing fleshy albumen ; having the radicle 

 turned towards the hylum. Small glabrous shrubs or subshrubs. 

 Leaves obovate, green, rather fleshy. Stipulas oval, membra- 

 nous, foliaceous, deciduous, the 2 

 upper ones constituting an invo- 

 lucel. Flowers terminal, soli- 

 tary, elongated, white. Fruit 

 follicle-formed. 



1 H. LONGIFLORA (Swartz, obs. 

 p. 135. t. 5. f. 1.) flowers hexan- 

 drous ; corollas 6-cleft, with li- 

 near-lanceolate, rather revolute 

 segments. Ij . S. Native of Ja- 

 maica, Guadaloupe, Martinico, 

 Cuba, the hotter parts of Mexico, 

 on the decayed parts of old trees, 

 and among moss. H. parasitica,

FIG. 85. 



Jacq. amer. p. 96. t. 66. Perhaps there are two species confused 

 under this name. Lobes of calyx, ex Jacq. 6, but according to 

 Swartz 2-4, and in the specimens examined only 2. The involucel, 

 according to Swartz, is 6-leaved, but according to Jacquin and the 

 specimen examined only 2-leaved, constantly composed of the 2 

 superior stipulas. The branches, according to Swartz and Jac- 

 quin, are terete, but according to the figure in the fl. mex. and 

 the specimen examined tetragonal. In the figure of bot. mag. 

 t. 721. the branches are round, the leaves ovate, smooth ; the 

 involucel of 2 leaves, limb of the corolla of 6 twisted seg- 

 ments, and the limb of the calyx apparently 6-cleft. The flowers 

 are white and very fragrant. 



Long-flowered Hillia. Fl. Feb. March. Clt. 1789. Shrub 

 2 feet. 



2 H. BRASILIE'NSIS (Cham, et Schlecht. in Linnsea. 4. p. 201.) 

 corollas 6-cleft, hexandrous : segments ovate-lanceolate, obtuse. 

 Tj . S. Native of Brasil. Leaves oval, acuminated. Tube of 

 corolla 3 inches long. 



Brasilian Hillia. Shrub. 



3 H. TETRA'NDRA (Swartz, fl. ind. occ. 1. p. 630. icon. t. 11.) 

 flowers 4-cleft, tetrandrous : segments ovate. Tj . S. Native 

 of Jamaica, on the high mountains among the roots of bushes. 

 Leaves obovate, pale green. Roots creeping, tuberous. Lobes 

 of calyx 4, cuneate-oblong, 2 of which are deciduous. Leaves 

 of involucel 4, 2 of them smaller than the other two. Flowers 

 yellowisli-white, having the tube nearly an inch long and tetra- 

 gonal. Seeds pappose at the apex. Perhaps H. Tuxtlensis, 

 Moc. et Sesse, fl. mex. ined., which was collected about Tuxtla 

 in Mexico, is distinct from this species, in consequence of the 

 calvx being 2-lobed, and the involucel 2-leaved. 



Tetrandrous Hillia. Fl. June, July. Clt. 1793. Shrub 3 

 to 4 feet. 



Cult. The species of this genus delight in a mixture of turfy 

 loam, peat, and sand ; and cuttings will soon strike root in the 

 same kind of soil, or in sand under a hand-glass, in heat. 



IX. HYMENO'POGON (from vpiv, hymen, a membrane, 

 and Trwywv, pogon, a beard ; the seeds are furnished with a mem- 

 branous appendage at each end). Wall, in Roxb. fl. ind. 2. p. 

 156. D. C. prod. 4. p. 351. but not ofBeauv. 



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

 tube, and a 5-parted permanent limb. Corolla salver-shaped, 

 with a very long tube, and a 5-parted limb. Stamens 5, inserted 

 in the inflated apex of the tube, inclosed. Stigma oblong, 2- 

 lobed : lobes linear. Capsule oblong-clavate, 10-nerved, crowned, 

 2-celled; carpels dehiscing at the apex, cleft in the middle, 

 hence the capsule appears 4-valved. Placentas very narrow. 

 Seeds imbricated, linear, furnished with a membranous appen- 

 dage at both ends. A small crooked shrub, with compressed 

 branchlets. Leaves approximate, acuminated, membranous, pu- 

 bescent above, and villous beneath. Stipulas permanent, mem- 

 branous, ovate, acute, ciliated. Corymbs nearly terminal, 

 trichotomous, bracteate. Flowers very long, white, inodorous, 

 pubescent. 



1 H. PARASI'TICUS (Wall. 1. c.) Jj . S. Native of the East 

 Indies, growing on trees, and sometimes on rocks, on Sheopore, 

 Chandagiri, near Hetounra, and between that place and Chit- 

 long. Stems rooting, as well as the branches, covered with 

 pale ash-coloured bark. Leaves 5-7 inches long. Seeds linear, 

 smooth, terminated by a long linear membranous, sometimes 

 bifid appendage, measuring altogether 3 lines in length.
