3. SICYOS Linn. [Palunu.] 



Male flowers racemed or corymbed. Calyx-tube very broadly cam- 

 paniilate, with 5 small teeth, or entire. Corolla rotate, 5-parted, the 

 segments triangular-ovate and whole confluent with the calyx. Sta- 

 mens confluent by the base of their filaments in a short column ; an- 

 thers 2-5, sessile at the apex of the column, connate in a head or 

 more or less free, the cell curved or very flexuose. Ovary wanting. 

 Female flowers usually in the same raceme as the male, at the apex of 

 a more or less elongated peduncle, rarely solitary. Calyx above the 

 ovary and corolla as in the male. Stamens none. Ovary ovate or sub- 

 ulate, sometimes long-beaked, setose or aculeate, or rarely smooth, 1- 

 celled; style short, with 3 stigmas ; ovule one, hanging from tlie apex 

 of the cell. Fruit leathery or somewhat woody, angled. Seed with a

 prostrate herbs, with angled, lobed, or cleft membranous leaves ; 3- 

 cleft tendrils, minute flowers, and small fruit. — The Hawaiian species 

 belong to the section or 



Subgenus Sicyocarya. Fruit ovate-pyramidal or oblong, 4-6-

 much thickened. Anthers 2-5, contorted and adnate at their bases; 

 the connective narrow.

 Hawaiian Islands.

 Leaves lobed, cordate at the base. Male flowers 1 or 2 lines in 



diameter S. paclnjcarpus. 



Leaves barely lobed. Male panicles umbellate or a long pedun-

Leaves barely or very deeply lobed. Male panicles long pedun- 



cled, 3-branched; flowers 3 or more lines in diameter. . . S. cucumerinus.
