 Allied to R. buxif blia, but quite distinct from R. incana. 



Royena-leaved Rondeletia. Shrub. 



k Shrubs with 'axillary thorns. Perhaps the spines are 

 either rameal or peduncular. Fruit unknown, and therefore the 

 genus to which they properly belong. 



28 R. LEPTACA'NTHA (D. C. prod. 4. p. 410.) spines oppo- 

 site ; leaves broad-oval, acutish, glabrous on both surfaces, but 



rather pilose when young as well as the branches ; peduncles

 ing 3-5 flowers at the apex. f? . S. Native of Cuba, about

 calyx subulate. Corolla 5 lines long. 

 Slender-spined Rondeletia. Shrub. 



29 R. BRACHYACA'NTHA (D. C. 1. c.) spines opposite ; leaves

} Species not sufficiently known.

 cuneated at the base, obtuse and acuminated at the apex, petio- 

 late, quite glabrous, coriaceous, paler beneath ; peduncles axil- 

 lary, opposite, corymbose, many-flowered. J? . S. Native of 

 Martinico. Veins of leaves black. Leaves 4 inches long and 

 2 broad. Stipulas ovate, acute, short. Bracteas glabrous 

 outside and hairy inside. Capsule globose. R. parviflora, 

 Spreng. syst. ex herb. Balb. appears to be a distinct plant from 

 the present. 



Small-flowered Rondeletia. Shrub. 



31 R. RHYNOHOSPORA (H. B. et Kunth, nov. gen. amer. 3. 

 p. 395.) leaves oblong-elliptic, acute, on short petioles, pubescent 

 above and on the branches, but clothed with canescent tomen- 

 tum beneath ; panicles terminal ; seeds beaked at botli ends. 

 17 . S. Native of New Granada, near Honda. The flowers 

 are unknown. 



Beaked-seeded Rondeletia. Shrub 4 to 6 feet. 



32 R. ? DISPE'RMA (Jacq. amer. p. 59.) leaves oval, obtuse, 

 petiolate, glabrous ; racemes axillary, compound, loose, trifid ; 

 fruit somewhat baccate, 2-seeded. ^ S. Native of South 

 America, in the woods of Carthagena, in rocky places ; very 

 frequent in the islands of Baru and Tierra Bomba. This plant 

 should probably be removed from the genus as well as from 

 the present tribe. Flowers sweet-scented, purplish white. 

 Perhaps a species of Cdnthium. 



Two-seeded Rondeletia. Tree 15 feet. 



33 R.? CORIA'CEA (Spreng. syst. 1. p. 707. but not of Wall.) 

 leaves oval-oblong, coriaceous, shining above, but clothed with 

 very short velvety down beneath as well as on the branchlets ; 

 stipulas semi-orbicular, furnished with a pungent tooth in the 

 middle ; cymes terminal ; calyxes and corollas 5-parted, rather 

 hispid ; stamens exserted. Tj . S. Native of equinoxial Brazil. 

 Mussae'nda coriacea, Spreng. neu. entd. 2. p. 145. It is pro- 

 bable that the plant is neither a Mussce'nda nor a Rondeletia, 

 according to Cham, et Schlecht. in Linnaea. vol. 4. p. 165., but 

 the structure of the fruit is entirely unknown. 



Coriaceous-leaved Rondeletia. Shrub. 



Cult. The species thrive well in a mixture of sand, loam, 

 and peat ; and cuttings of them are easily rooted if planted in 

 a pot of sand, plunged in heat under a hand-glass. All are 

 shrubs of very little beauty or interest.
