72 FLORA OF NEW ZEALAND. [ Passifloree. 
Nar. Og». XXVIII. CUCURBITACEA, Juss. 
Gen. I. SICYOS, L. 
Flores unisexuales. FL. maso. racemosi. Calyx campanulatus, 5-dentatus. Corolla calyce continua, 
5-loba. Stamina 3-5; filamentis in columnam coalitis; antheris liberis, 1-locularibus. Fr. ram. capitati, 
umbellati v. solitarii, pedunculati. Calycis limbus campanulatus, 5-dentatus. Ovarium l-loculare; ovulo 
solitario; stylo 3-fido. Fructus ovatus, coriaceus, hispidus v. spinosus. 
Prostrate or climbing, alternate-leaved herbs, with tendrils from the axils of the leaves, and axillary unisexual 
flowers. Male flowers racemose. Calyx campanulate, five-toothed. Corolla five-lobed, continuous with the calyx. 
Stamens three to five, their filaments united into a column; anthers free, one-celled. Female flowers capitate on an 
axillary peduncle, solitary or umbellate. Calyx-tube adnate with the (one-celled, one-ovuled) ovary ; limb campanu- 
late, free, five-toothed. Style trifid. Fruit a coriaceous, hispid or spinous, ovate, one-celled nut; seed one, pen- 
dulous. —A small, chiefly western American genus, of which the present is the only one of the large Natural Order 
to which it belongs, found in Tasmania or New Zealand. The species of Sicyos are variable, and some of them very 
widely spread, especially the present, which is found in Tasmania, Australia, Norfolk Island, the United States, 
Mexico, and throughout South America to Bonaria and South Brazil. —A few species inhabit the Pacific Islands, 
and with the present are the only extra-American ones known. (Name, osxvos, a cucumber; from the habit of this 
plant, which is allied to that genus.)

Has. Northern and Middle Islands; chiefly on the eastern coasts, Forster, etc. Nat. name, “ Ma- 
whai,” Col. : 
Stems trailing or climbing, pilose or smooth. Leaves petiolate, very variable in size, two to six inches across, 
scabrous or smooth, broadly reniform, cordate or ovate, three- to seven-lobed ; lobes acute, toothed, deeply bilobed, 
cordate at the base, with a rounded sinus. Flowers variable in size; male in racemes, 1-4 inches long, pedicellate, 
smooth or covered with long glandular hairs, 2-5 lines broad; female smaller, capitate on a short peduncle, corolla 
pedicellate. Fruits five to seven, ovate, 3-3 inch long, pilose or smooth, but covered with spines, which, being 
barbed, are the means of attaching the seeds to animals, and so dispersing them.—I can find no difference between 
these and American specimens, in either foliage or inflorescence ; it varies extremely in size in both hemispheres. 
NAT. Ord. XXIX. PASSIFLOREAL, Juss. 
Gen. I. PASSIFLORA, 2. 
Flores uni-bi-sexuales. Sepala 4-5. Petala 4-5, basi corona filamentorum instructa. Stamina 4-5 ; 
filamentis basi in columnam pedicello ovarii aceretam coalitis, superne liberis, divaricatis; antheris 2-locu- 
laribus, versatilibus. Ovarium stipitatum, ovoideum, 1-loculare; ovulis plurimis, placentis 3 parietalibus 
affixis; stylis 3, stigmatibus capitatis. Bacca carnosa. Semina numerosa; testa reticulata v. rugosa, 
crustacea. 
The New Zealand Passion-flower is a perfectly smooth climbing plant, with alternate, simple, petiolate leaves, 
axillary tendrils, and small axillary panicles of green flowers, that only differ from those of the American
