CUCURBITACE.E. 



649 



denticulate, thin and membranaceous, sparsely roughened on both 

 sides with small papillae. Flowers monoecious ; both kinds often pro- 

 duced from the same axils. Male raceme simple, short and rather few- 

 flowered, with the peduncle scarcely equalling the leaves ; the flowers 

 only 2 lines in diameter, of the same structure as in S. parviflorus; 

 the united filaments forming a filiform column nearly as long as the 

 corolla. Anthers apparently only 3, connate into a sinuous mass. 

 Fertile peduncle 2 lines long, probably bearing a number of female 

 flowers in a head, as there are 3 or 4 fructified ovaries or young 

 fruits: these are ovate, very glabrous, wholly unarmed and naked, 

 pointed but not beaked, somewhat compressed, 2 or 3 lines long. 

 Ovule and the half-grown seed solitary from the summit of the single 

 cell. 



§ 2. SICYOCARYA. — Fructns ocato-pyramidatus vel oblongus, 4:-6-angulatus (raris- 

 sime triquetei"), inermis, pi. m. rostratus; pericarpio incrassato. Anthercc 2—5, 

 sinuosce, basi connatce; connectivo anyusto. 



Not being disposed to found a genus upon the form and texture of 

 the fruit, I characterize the following Hawaiian species under a dis- 

 tinct section or subgenus of Sicyos. One of them, S. -pad* year pus, has 

 already been published : but its mature fruit was not known. The 

 second has the same habit as well as structure. The third, S, cucu- 

 merinus, would never by itself be taken for a Sicyos; yet it appears 

 to be a strict congener of the two others. /Sicyos triqueter of Mogino 

 & Sesse, known to DeCandolle only by a drawing, appears also to 

 belong to this group. The filaments, as in true Sicyos, are perfectly 

 united to the summit; the cells of the anthers, which are only 

 slightly sinuous, are separated by a somewhat dilated and plane, 

 although narrow connective ; indicating that the anomalous S. mon- 

 tanus, of Poeppig and Endlicher, should perhaps be retained as a 

 third section, rather than excluded to form the type of a new Sicyoid 

 genus.* The fruit of the latter is said to be obtusely pentagonal, but it 

 is not so delineated in the plate. 



* § 3. SICYOPSIS. — Fructus obovatus, turgidm, inermis, hirsutus, infra apicem 

 obtusissimum dentibus cahjclnu subnlatis defiexis coronatus; " pericarpio baccato." 

 Colunma staminum extremo a pice trifida. Antherce 3 liberce, seu 5 triadelphce; connec- 

 tivo dilatato piano utrinque emarginato.
