554 LX. MELASTOMACE2E. (C. B. Clarke.) [Hemecylon. 



* Ultimate brancklets quadrangular (see also No. 21, 22, 24, 37, 40). 

 t Leaves usually more than 4 in. (nerves often distinct). 



3. 1H. Wight!!, Thwaites Enum. 113; leaves 3-4 in. subsessile elliptic- 

 lanceolate "base cordate, peduncle 0, pedicels clustered -f in., calyx-tube at 

 the time of flowering subcampanulate. 



WESTERN PENINSULA ; Canara ; Ritchie. CEYLON, alt. 3000-4000 ft., Thwaites. 



A. tree 25 ft. ; ultimate branchlets stout, acutely quadrangular. Secondary nerves 

 conspicuous, marginal looped nerve obscure. Buds obtuse, calyx-limb 4-dentate. 

 Petals blue. Berry ^~ in. diam., globose. United by Triana with M. amplexicaule 

 No. 24, which has round stems, much larger flowers, and the calyx-tube at the time 

 of flowering saucer-shaped. 



4. M. Hooker!, Thwaites Enum. 113 ; leaves 6-9 in. sessile oblong-lan- 

 ceolate base cordate, peduncle 0, pedicels \ in. clustered, calyx-tube at the time 

 of flowering saucer-shaped. Triana in Trans. Linn. Soc. xxviii. 158. 



CEYLON ; alt. 1000 ft. ; Thwaites. 



An erect shrub 8-12 ft., sparingly branched ; ultimate branchlets stout, acutely' 

 quadrangular. Leaves very conspicuously nerved, secondary nerves running into a 

 conspicuous marginal nerve. Buds obtuse, but apiculate ; calyx-limb obscurely 4- 

 lobed. Petals blue. Berry | in. diam., spherical, finally black -purple. Thwaites 

 has sent (under No. 2686*) examples marked " M. Hookeri, variety with exalate 

 branchlets, sessile flowers." These examples have perfectly round branchlets and 

 seem in all respects identical with No. 25 M. macrophyllum, Thwaites. 



5. M. G-riffithianum, Naud. in Ann. Sc. Nat. ser. 3. xviii. 274 : leaves 

 5-7 by 1-1 in. nearly sessile linear-lanceolate rounded or somewhat acute at 

 the base, peduncle 0, pedicels -| in. clustered. Triana in Trans. Linn. Soc.

MERGUI ; Griffith (No. 2323 Kew Distrib.). 



Ultimate branchlets 4-winged. Leaves somewhat opaque, secondary nerves visible, 

 marginal quite obscure; petiole 0- in. Flowers rather large, pale blue (Griffith); 

 buds obtuse. Calyx-tube at the time of flowering funnel-shaped, limb nearly trun- 

 cate. Disc depressed, conspicuously rayed. M. Horsfieldii, Miquel, said by Kurz 

 (Journ. As. Soc. 1876, pt. ii. 54) to be a synonym of M. Griffithianum, widely 

 differs ; of M. Campongum, Miquel, also given as a synonym by Kurz, no authentic 

 specimen exists at Kew. In Journ. As. Soc: 1877, pt. ii. 82, and For. FL i. 515, 

 Kurz quotes for M. Griffithianum Heifer's No. 2331, from which it is clear that he 

 refers to No. 20 M. grande, Retz, var. merauica. 



6. IK. eleg-ans, Kurz in Journ. As. Soc. 1872, pt. . ii. 307, For. Fl. i. 

 514 ; leaves 3-4 in. elliptic obtuse narrowed at the base, petiole -f in., pedun- 

 cles in. 3 or 4 together carrying mostly simple umbels, pedicels in. 



i,- SOUTH ANDAMAN ISLAND ; Kurz. 



A shrub; ultimate branchlets distinctly quadrangular. Leaves with the secondary 

 nerves visible, marginal quite obscure. Peduncles quadrangular. Flowers blue 

 (Kurz). Calyx-tube somewhat large, at the time of flowering saucer-shaped ; disc on 

 the apex of the ovary depressed, prominently rayed. 



VAR. dichotoma ; leaves 3-4 in. subsessile ovate-elliptic acute or shortly acumi- 

 nate, cymes very short, peduncle 0- in., pedicels ^-~ in. Malacca, Griffith (No. 2324 

 Kew Distrib.) ; Mount Ophir, Maingay No. 818, 820. Branchlets somewhat flat- 

 tened, repeatedly forked, ultimate quadrangular, at least under the nodes. Leaves at 

 the base rounded or acute but not at all acuminate, secondary nerves conspicuous,
