more frequently dioecious than monoecious. In flowers where perfect 
stamens occur the ovary is either abseut or rudimentary ; aud in plants 
with a well developed ovary the Btamens, 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 Peuang, were 
issued by Wallich as No. 4024 of his Catalogue under the name Penta- 
loba macrayhiilla ; while specimens of the female were issued as Nos. 7501 
and 7513 (nn-named, but with the notes by R. Brown). These notes are 
as follows: on No. 7501, " Urticeae habi'u ; arborescens ; " and, on No. 
7513, " huh'terminata fruttcosa, decumb. ; foltis alter nis integerriniis, 
v it i ■ in < v ' irniJ/tiicttit is, <j laberr irn pcJitucitl is a x Mar ib us." 
Wallich was wrong in referring this plant to the genus PentahJ/a 
of Loureiro, for that author describes no appendages to its stamens. 
It belongs most certainly to the genus Prosthesis of Blume (Bijd. 866.) 
2. A. Ki'NS i TjKKIAXA, King, n. sp. A glabrous shrub or small tree ; 
the brauehlets Btriate, sometimes lenticellate. Leave* subcoriaceous, 
oblong-lanceolate, acuminate or candate-acuminate, sometimes minutely 
and obscurely serrulate, very much narrowed to the base; upper surface 
smooth aud shining ; lower dull, rough frotn the numerous short trans- 
verse secondary nerves and 14 to 16 pairs of prominent ascending main 
nerves ; the midrib bold and suhrugose ; the reticulations minute and 
distinct ; length of blade 6 to 10 in., breadth 2'2o to 3 in., petiole -^5 
to *5 in. Stipules lanceolato, '25 in. long. Female flowers in axillary, 
often crowded, fascicles or very short racemes of 3 to 8, bracteolute, tho 
pedicels longer than the leaf-petioles. Sepals ovate, obtuse, imbricate, 
strongly nerved, tho edges ciliate, shorter than the petals. Petals erect, 
the tips not reflexed, ovate-acute, rigid. Stamens with short flat lila- 
ments, each inserted into the apex of a lobe of the deeply 5-lobed disc. 
Ant fairs (without pollen) broad, adprcsscd to the ovary, each with 2 linear 
anterior and oue largo dorsally-attached halbert shaped membranous 
appendage, tho latter conniving into a cone round the upper part of the 
ovary. Ovary sessile, ovoid-conic; the style exserted, cylindrio. Capsule* 
ovoid, glabrous, shining, Binooth, "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, Kings 
collector ; at low elevations. This species is more often practically monoe- 
cious than A, WuUirhi.nm. to which it is closely allied. It differs, 
however, from that species in its much more acuminate rougher leaves, 
and also in its capsules aud seeds.
