124 . cucurbitacEjE. [Karivia. 



1. KARIVIA, Am. 



Calyx urceolate, with 5 small teeth at the base of as many petals, which 

 appear to form part of the calyx. Male flowers : Stamens 3, with distinct 

 filaments inserted at the base of the calyx. Anthers with a broad connecti- 

 vum, two with 2 cells each, the third usually 1 -celled, more or less sinuous. 

 Female flowers : Style cylindrical, with 3 large capitate stigmas. Berry glo- 

 bular or ovoid, not beaked. — Leaves very variable, entire or lobed. Flowers 

 small, the males in short racemes or umbels, the females solitary. 



A small genus, limited to Africa and tropical Asia, united by Thwaites with Zehneria, 

 Endl., and both scarcely distinct from Bryonia. 



1. K. umbellata, Am. in Hook. Journ. Bot. iii. 275. A glabrous 

 climber, with little or none of the asperities so general in Cacurbitacea. 

 Leaves exceedingly variable in shape, usually 2 or 3 in. long, on short peti- 

 oles, deeply cordate at the base, and more or less angularly 3- to 5-lobed, the 

 middle lobe the longest, the lower ones very spreading ; sometimes heart- 

 shaped and toothed only, sometimes divided almost to the base. Male flowers 

 2 \ lines long, with short broad lobes (petals) and minute spreading teeth be- 

 tween them on the outside ; the very short racemes, either sessile in the axils 

 or on a peduncle of near an inch. Female flowers solitary, sometimes in the 

 same axils as the male raceme. Berry small, ovoid-oblong. — Harlandia 

 bryonioides, Hance in Walp. Ann. ii. 648. Bryonia umbellata, Willd. ; DC. 

 Prod. iii. 305. 



Hongkong, Hance, Wright. Extends over the greater part of India, and abundant in the 

 Archipelago. Dr. Hance's specimens were by mistake referred by Seemann to the Zehneria 

 mysorensis, which may be at once distinguished by the male flowers, which are shorter, more 

 broadly campanulate, with very spreading lobes (or petals) as long as the tube. The berries 

 are also shorter and more globular. This species has not yet been found in China. 



2. 5ICHMANDRA, Am. 



Calyx campanulate, with 5 small teeth at the base of the 5-lobed corolla 

 which appears continuous with it. Stamens 3, inserted near the petals, in the 

 tube of the calyx ; filaments short, free. Anthers with a broad connectivum 

 projecting beyond the cells, 2 with 2 cells each, the third 1-celled. Ovaiy 

 oblong, contracted at the top. Stigmas 3, sessile. Berry oblong, indehiscent, 

 obtuse or contracted into a beak at the top. — Flowers small, the males in short 

 racemes or solitary, the females always solitary. 



A small genus, spread over Africa and tropical Asia. 



1. JSS. odor at a, Hook. fil. and Thorns. Stems slender, glabrous or 

 slightly pubescent. Leaves broadly triangular or cordate, acuminate, about 

 1^ in. long, sinuately toothed or 3- or 5-lobed, thin, but very rough on the 

 upper side, on petioles of £ to 1 in. Pedicels filiform, 1-flowered, 3 to 6 lines 

 long, usually 1 male and 1 to 3 females in the same axil. Male flowers about 

 3 lines long, and cleft to about the middle, the small subulate calyx-teeth re- 

 curved. Connective of the anthers broad and membranous, the anther-cells 

 reaching to about ■% of its length. Female flowers rather small. Berry oblong, 

 obtuse, not beaked, about £ in. long, in the Hongkong variety, shorter and 

 globular in the more common Indian form. — Bryonia odorata. Ham. in Wall.
