MELASTOMACEjE. 265 



S 



». Branchlets obtnse-angled ; leaves elliptical, bluntish; usually with a point, 3"-4" 

 long : glandular teeth distant, chiefly beyond the middle,' usually early disappearing ; bracts 

 Usually 2 ; petals white, with a crimson base, or rosy. — M. leucantha, Sw. — Tussac's and 

 Descourtil's figures belong to its rose-coloured form. M. hifrons, Naud., characterized by 

 pointed spurs and usually 4 bracts, agrees with a younger state of it sent from Jamaica by 

 Mr. March. ' 



;8. jmrnurea, Sw. (nou Tuss.). Branchlets subcyliudrical ; leaves ovate-lanceolate, taper- 

 pointed, 3 '-6"long : glandular teeth crowded in the younger state, but sometimes disappearing 

 with age; bracts usually 4, elliptical or elliptical-lanceolate; petals purple.- — A shrub of less 

 high growth (according to Swartz), to which may be confidently referred M. nana, Naud. : 

 but a contrary statement of the respective growth of M. leucantha and purpurea has been 

 made by M'Padyen. 



Hab. Jamaica ! (a and j3) : all coll., common on the higher mountains. 



84. IXI, bnllifera, Gr. Leaves elUptical or elliptical-lanceolate : upper side idih two 

 minute ovate tumours between the bases of nerves ; tracts 4-2, linear and somewhat spathu- 

 late towards the top (sometimes spathulate-lanceolate and convolute), ■uninerved ; calyx-lobes 

 s"ubulate; anther-spurs short, alternately conical and bitubercled. — Tuss. Fl. 1. t. t. — M. 

 purpurea, Tuss., Naud. (non Sw.). M. rosea, Mac/', {exclus. synon. 7\iss.). — An arbores- 

 cent shrub, about 16' high ; leaves bluntish, vrith a point, usually smaller than in the pre- 

 ceding species, 2"-3" long : the younger ones minutely serrate with distant glandular teeth ; 

 petals beautifully scarlet (Fd.). — Hab. Jamaica!, Fd., March, on the higher mountains, e.g. 

 S. Katherine's Peak, Portland Gap. 



21. DAVYA, DC; Naud. {l.u. \%.p. 134). 



Calyx-limb spreading, repand or obscurely lobed. Anthers 10-8, opening with a single 

 terminal pore : spiir postei^or, elongated, reflexed and parallel to the anther. Ovary free, 

 5-3-locular. — Arborescent or scandent shi-ubs ; leaves petioled, S-&-nerved : nerves commu- 

 nicating by distant, oblique or tranverse veins; panicle or cyme termifial; petals obovate."^ 



85. D. adscendeus, Gr. Scandent, glabrescent ; leaves broadly elliptical, pointleted ; 

 divisions of the panicle terminated by corymbiform cymes ; anther-spur linear, bifid : divi- 

 sions setaceous ; ovary 5-locular. — Melastoraa, Sw. ! Adelobotrys scandens, Maqf. (non 

 Jubl.). — A scandent shrub, 10'-30' high : branches - elongated, obtuse-angled ; down feiTu- 

 giuous, scattered, disappearing on the full-grown branches and leaves ; leaves 3"-5" long, 

 2i"-4" broad, trinerved, with a strong, accessory, juxtamarginal pair, obscurely denticulate 

 and ciliate ; panicle much branched : pedicels 2"'-3"' long ; calyx narrowly campanulate, 

 equalling the pedicel : limb with minute teeth ; petals flesh-colonred, usually 5, a little 

 longer than the calyx-lobes ; capsule ovoid-globose. — Hab.' Jamaica!, Macf., Al., Wils., 

 Wullsckl., in damp mountain woods, especially in the northern districts, cUmbing on trees, 

 Macf.,Al., Wils.; [Mexico !, /wjy ««««»]. 



86. D ciliata, Naud. Brunches cylindrical, glabrescent; leaves broadly elliptical, 

 pointleted, glabrous, suboiliate ; divisions of the panicle spreading, terminated hy few-flow- 

 ered flower-heads. — Leaves 6"- 5" long, 4"-3" broad, polished, trinerved, usually crenate, 

 with the short crenatures broad and truncate : the pair of leaves not quite of the same size ; 

 down perfectly disappearing on the full-grown brauches and leaves, with the exception of 

 single short cilia between the crenatures, or even these wanting, if the leaf is entire ; pani- 

 cles short, with the clusters distant, terminal and axillai-y, the axillary ones exceeded by the 

 leaves ; calyx-tube ovoid, 2"' long, with 10 (-8) prominent, longitudinal ribs, and covered 

 with scattered, spreading hairs, surrounding the copsiJe and appressed to it : limb short, 

 obscurely 5-lobed. My specimen has only immature fruits : Naudin's species will perhaps 

 prove a glabrescent form of D. scandens (Adelobotrys, DC, Melastoma, Anbl. t. 172), 

 from which it is distinguished chiefly by the leaves and the leaf-ribs being perfectly glabrous. 

 —Hab. Trinidad!, Or.; [Guiana]. 



23. CYCNOPODIUM, Naud. (I. <;. i.p. 52, and 18. p. 118). 



Calyx-limb 4-lobed. Anthers 8, opening with a single terminal pore : connective pro- 

 duced at the base into a short tail, continuous with the hanging, posterior, short spur.
