4. LABISIA, Lindl 



Small shrubs, -with a creeping rhizome and short simple stem. Leaves 

 lanceolate, acuminate, primary nerves nearly at right angles to the midrib ; 

 petiole dilated at the base. Flowers small, white, in axillary panicled spikes ; 

 bracts very small. Calyx 5-toothed. Corolla 5-partite; segments ovate, 

 induplicate-valvate in bud. Stamens 5, filaments short ; anthers oblong-linear. 

 Ovary superior, globose; style cylindric, stigma small; ovules few. Fruit 

 small, globose, 1-seeded. Seed globose, base hollowed, albumen smooth ; em- 

 bryo transverse. Species 2, Malayan. 



1. Xi. pothoina, Lindl. in Sot. Reg. 31, t. 48 ; leaves glabrous or puberu- 

 lous beneath entire or nearly so, flowers very shortly pedicelled clustered on the 

 rachis of the linear rusty-pubescent panicle. Ardisia pumila, Blume Bijd. 688 ; 

 A. DC. in Trans. Linn. Soc. xvii. 135, and Prodr. viii. 137 ; Scheff. Myrsin. 92. 

 A. ? spicata, Watt. Cat. 2273. 



MALACCA and SINGAPORE ; Wallich, &c. DISTRIB. Sumatra to Borneo. 



Stem 6 in. Leaves 8 by 2 in., primary nerves horizontal, very numerous, close ; 

 petiole 1-3 in., more or less winged its whole length. Peduncles 1-2 in., from 1-3 

 penultimate axils ; spikes 1-4 in. Petals ^ in., dotted. Berry |- in. diam. 



VAR. pothoina proper ; petiole winged throughout its length. 



VAE. lanceolata, Scheff. Myrsin. 93 ; petiole 2-4 in. not winged; base of leaf 

 narrowed or rounded, pedicels |- in. Singapore, Lobb. DISTRIB. Sumatra, Borneo. 



5. ARDISIA, Swartz. 



Shrubs or small trees. Leaves petioled. Floiuers hermaphrodite, in axillary 

 or terminal, simple or compound umbels or racemes ; bracts small, deciduous 

 (except in A. involucratd). Calyx 5- (rarely 4-) lobed, (sometimes 3-lobed in 

 A. porosa}, persistent, often somewhat enlarged in fruit. Corolla red, white, or 

 spotted, 5-partite ; segments acute (in A. membranacea emarginate), twisted to 

 the right in bud. Stamens 5 ; filaments very short (except in A. membranacea) ; 

 anthers free, ovate-lanceolate, acute (in A. membranacea small, round), (in 

 A. porosa opening by terminal pores). Ovary globose, narrowed upwards (in 

 A. membranacea -obovate-oblong) ; style cylindric, often much longer than the 

 corolla-lobes, stigma punctifonn; ovules few. Fruit globose or subglobose. 

 Seed solitary, globose, albumen pitted or ruminated; embryo horizontal. 

 Species 200, all tropical. 



The Indian species are very uniform in floral structure, except A. involucrata, 

 membranacea and porosa, which differ possibly generically from all the rest as much 

 perhaps as do Pimelandra and Amblyanthus, 



* Panicle terminal, l.-2-divided, branches ending in corymbs often contracted 

 almost to umbels, bracts not leaf-like. 



t Panicle stout, compound. 



1. A. crassa, Clarke; leaves narrow-oblong acute at both ends, panicle 

 rusty-pubescent, branches and pedicels exceedingly thick, corolla broad short. 



MALACCA ; Maingay. DISTRIB. Borneo. 



Branches round, stout, ending in a much-flattened panicle. Leaves 8 by 2 in., 

 parallel-sided, subentire, coriaceous, glabrous, primary nerves nearly at right angles 

 to the midrib ; petiole in. Panicle 5 in. (including the peduncle) ; branches remote, 

 flattened, again divided ; pedicels - in., umbelled, thickened upwards ; bracteoles
