FLORA OF THE HAWAIIAN ISLANDS. 107 



climbing by means of tendrils. Leaves cordate, roughened, or hispid 

 petioles. Calyx-tube obovate, constricted in the throat. Fruit glo- 

 bose, large, yellow or greenish or reddish. 



Cultivated from time immemorial by the natives ; probably introduced. Native coun- 

 try impossible to designate, as this species has been cultivated by man in most all tropical 

 regions for so long a time. 



3. SIOYOS Linn. [Palunu.] 



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

 panulate, 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 the apex 

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

 membranaceous testa. Glabrous or pubescent-scabrous, climbing or 

 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- 

 (rarely 3-) angled, unarmed, and more or less beaked ; the pericarp 

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

 the connective narrow. 



A small genus, mostly found in the hot parts of America, the subgenus peculiar to the 

 Hawaiian Islands. 



Leaves nearly or quite glabrous, large; fruit more than 3 lines long. 

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



diameter. S. pachycarpus. 



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

 cle; flowers 5 lines in diameter when expanded S.macrophyllus. 



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



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

 Leaves hispid or papillose scabrous, especially beneath, small. Flowers 



very small, as are the fruits which are 2 lines long. . S. microcarpus.. 



1. S. (SICYOCARYA) PACHYCARPUS Hook and Am. (Enum. No. 142.) 

 Stems slender, angled, nearly glabrous, sometimes with glandular- 

 tipped hairs. Leaves membranaceous. 3'- 5' in diameter, rounded and 

 cordate-angled, 3 - 7-lobed, the terminal lobe the longest ; the margin 

 of the leaf remotely denticulate, the lower surface somewhat papil- 

 lose-scabrous ; petioles l'-2' long. Male flowers small, a line or two 

 in diameter, in racemose, simple or compoundly branched panicles. 

 Female flowers numerous in a small head at the summit of the'pedun-
