Syzygium.'] myrtace^e. 119 



few-flowered, seldom longer than the leaves. Calyx-teeth very short and 

 broad. Petals 4, small, not cohering as in most species of the genus. Ovules 

 about 4 in each cell. Berry 4 to 6 lines in diameter. Seed single, the thick 

 cotyledons not consolidated. 



In ravines, Champion and others. On the Chinese continent it extends northward to Amoy. 



2. S. odoratum, Hook, and Am. Bot. Beech. 187, but perhaps not of 

 DC. A glabrous shrub, with slightly compressed branches. Leaves ellipti- 

 cal or oblong-lanceolate, acuminate, 1^- to 2 in. long, narrowed into a petiole, 

 shining above ; the veins not very prominent, and uniting into a marginal one 

 about \ a line from the edge. Cymes few-flowered, compact, mostly terminal 

 and shorter than the leaves. Flowers scarcely pedicellate. Calyx-teeth 4, 

 broadly orbicular. Petals usually cohering and falling off together. 



In the Happy Valley woods, Champion and others. Also on the adjacent continent, but 

 not known out of S. China. It is at first sight very similar to the S. cymosum, DC. (S. 

 frondosum, Wall.), but in that species, besides minor differences, the lateral veins are very 

 numerous and parallel, running out almost to the edge. 



3. S. nervosum, DC. Prod. iii. 260. A large tree, quite glabrous. 

 Leaves ovate or oval-elliptical, obtuse or shortly acuminate, 3 to 6 in. long, 

 usually of a pale green ; the principal lateral veins distant from each other, 

 and very prominent underneath. Panicles usually arising from the leafless 

 nodes of the former year's wood, 3 or 4 in. long, very spreadingly branched 

 from the base ; the flowers usually 3 together, sessile at the ends of the ulti- 

 mate branches. Calyx not distinctly toothed. Berry very juicy and edible.

 Walp. Ann. ii. 629. 



Near the Albany barracks, Champion. Cultivated in the island, Hance. Spread over 

 northern and eastern India, the Archipelago, and northward to S. China. The berry much 

 eaten, and the tree often planted for its fruit. It is very near the S. Jambolana in habit 

 and inflorescence, but may be readily distinguished by the venation of the leaves. 



3. ACMENA, DC. 



Characters of Syzygium, except that the calyx-tube is elongated and tapers 

 to the base. 



A genus which, if limited as proposed by Wight (as a section of Etigenia), comprises seve- 

 ral Asiatic species, besides one or two Australian ones, to which last others would confine the 

 group. It is probable, however, that most of the species should be united with Syzygium. 

 The following one is as yet doubtful, only being known in fruit. 



] . A. Championi, Benth. in Kew Journ. Bot. iv. 118. A glabrous tree. 

 Leaves oval-elliptical or oblong, obtuse or obtusely acuminate, \\ to 2| in. 

 long, \ to 1 in. broad, tapering at the base into a short petiole, shining above ; 

 the lateral veins fine and scarcely prominent. Cymes few-flowered, terminal, 

 or in the upper axils shorter than the leaves. Pedicels very short. The 

 flowers have not been seen. Calyx (evidently just past flower) slender, 

 about 4 lines long, with 4 very short broad teeth. Berry ovoid-oblong, 5 or 

 6 lines long. Seeds 1 or 2, the cotyledons consolidated into a thick mass.
