more frequently dioecious than monoecious. In flowers where perfect 

 staraens occur the ovary is either absent or rudimentary ; and in phints 

 with a well developed ovary the stamens, although in most cases per- 

 fectly formed, contain no pollen. These sexual differences are accom- 

 panied by slight differences in the leaves, those of the male plants 

 being oblong-lanceolate, narrowed to the base and serrulate, while those 

 with female flowers have entire elliptic leaves with rounded or slightly 

 narrowed bases. Specimens of the former, collected in Penang, wer^ 

 issued by Wallich as No. 4024 of his Catalogue under the name Pentu' 

 loba viacrophylla; while specimens of the female were issued as Nos. 7501 

 and 7513 (un-named, but with the notes by R. Brown). These notes are 

 *a follows; on No. 7501, " Urticeae habitu ; arborescens ;" and, on No. 

 7513, •' Indeterminata fruticosa, decnmb. ; foUis alternis integerrimis, 

 coriaceis, ivipunctalis, glaberrimis, pedunculis axiUaribus:" 



Wallich was wrong in referring this plant to the genus Pentaloba 

 of Loureiro, for that author describes no appendages to its stamens. 

 It belongs most certainly to the genus Prosthesia of Blume (Bijd. 866.) 



2. A. KuNSTLERiANA, King, n. sp. A glabrous shrub or small tree ; 

 the branchlets striate, sometimes lenticellate. Leaves subcoriaceous, 

 oblong-lanceolate, acuminate or caudate-acuminate, sometimes minutely 

 and obscurely serrulate, very much narrowed to the base ; upper surface 

 smooth and shining; lower dull, rough from the numerous short trans- 

 verse secondary nerves and 14 to 16 pairs of prominent ascending main 

 nerves ; the midrib bold and subrugose ; the reticulations minute and 

 distinct; length of blade 6 to 10 in.; breadth 2*25 to 3 in; petiole -25 

 to 5 in. Stipules lanceolate, "25 in. long. Female flowers in axillary, 

 often crowded, fascicles or very short racemes of 3 to 8, bracteolate, the 

 pedicels longer than the leaf-petioles. Sepals ovate, obtuse, imbricate, 

 strongly nerved, the edges ciliate, shorter than the petals. Petals erect, 

 the tips not reflexed, ovate-acute, rigid. Stamens with short flat fila- 

 ments, each inserted into the apex of a lobe of the deeply 5-lobed disc. 

 Anthers (without pollen) broad, adpressed to the ovary, each with 2 linear 

 anterior and one large dorsally-attached halbert-shaped membranous 

 appendage, the latter conniving into a cone round the upper part of the 

 ovary. Ovary sessile, ovoid-conic ; the style exserted, cylindric. Capsules 

 ovoid, glabrous, shining, smooth, '5 in. long, dehiscing into three 

 narrow compressed pointed valves ; seeds one in each valve, ovoid, 

 white, shining. 



Singapore; Wallich, King's Collector. Perak ; Scortechini, King's 

 Collector; at low elevations. This species is more often practically monoe- 

 cious than A. Wallichiana, to which it is closely allied. It differs, 

 however, from that species in its much more acuminate rougher leaves, 

 and also in its capsules and seeds.
