96 FLORA VITTENSIS. 
Oxpo XLI. PASSIFLORACEZ:. 
In ‘The Botany of the Voyage of H.M.S. Herald’ I endeavoured to show that Passifloracee and 
Turneracee were so intimately connected as to constitute one Natural Order. I believe this view 18 now 
generally adopted. In Polynesia the Order is represented by one species of Passiflora and seyen species of 
Disemia, 
I. Disemma, Labill. Noy. Caled. 78. t. 79; Endl. Gen. n, 5100. Perigonium tubo brevi, 
subtus sulcato, limbi 10-partiti lobis 2-seriatis, intericribus minoribus corollinis, Corona faucis 
duplex, exterior filamentosa, filis 1l-seriatis, interior tubuloso-conica, longitudinaliter plicata, ore 
truncato v. denticulato. Urceolus carnosus, gynophori basim laxe cingens, 5-lobus. Stamina 5, peri- 
gonii laciniis exterioribus opposita, cum gynophoro longo connata; filamenta apice libera; anthere 
2-loculares, oblongz, incumbentes, longitudinaliter dehiscentes. Ovarium longe stipitatum, 1-loeu- 
lare. Ovula in placentis parietalibus tribus oo, co-seriata, horizontalia, anatropa. Styli 3, cylindrico- 
subclavati; stigmata subcapitata, Bacca subglobosa, 2-locularis, intus pulposa, placentis parietalibus 
3. Semina oo, ovata, compressa, funiculi apice in arillum carnosum expanso inclusa, testa crustacea 
scrobiculata, Embryo in axi albuminis carnosi orthotropus, cotyledonibus foliaceis, radicula umbi- 
lico proxima centrifuga.—Frutices, Passiflore facie, foliis alternis 3—-5-lobis, stipulis setaceis, 
pedunculis axillaribus solitariis v. geminis ]-floris, bracteis a flore remotis.—Pussiflore sp., Forst. ; 
Murucwje sp., Lindl. Coll, t. 36. 
This genus is contined to New Holland and the Pacifie Islands; the most eastern species is Disemma 
cerulescens, Seem.* D, aurantia is found in New Caledonia and the adjacent islets (Forster! Milne)), 
D. adiantifolia and Baueriana in Norfolk Island, and three new species in Viti. 
1, D. (?) Barelayi, Seem, (sp. nov.) ; petiolis eglandulosis; foliis glabris basi ovatis late 3-lobis, 
lobis oblongis v. obovatis obtusis mucronatis, medio productiore ; ext. ign.—In woods, Taviuni and 
Viti Levu (Barclay! n. 3459 in Mus, Brit.; Seemann! n. 190, ex parte). 
_ A small-leaved, delicate-looking plant, discovered in 1840 by Barclay, but his specimens, as well as 
mine, are not in flower. I confused it in the distribution of my specimens with the following species, 
which I collected in bud. Petiole almost filiform, 1-2 inches long. Blade of leaf 1-12 inch long 14 inch 
broad. The natives of Tayiuni, and probably also those of other parts of Viti, make wreaths of this creeper, 
which they wear around their heads. 
2, D. Storckii, Seem. (sp. noy.) ; petiolis medio 2-glandulosis; foliis glabris basi ovatis late 
3-lobis, lobis oyatis v. oblongis obtusis mucronatis, supra viridibus, subtus pallidioribus, 3-5-nerviis ; 
pedunculis apice 2-articulatis, 2-3-bracteatis, bracteis setaccis; florisus masculis 4-meris.—Taviuni, 
in woods (Seemann ! n. 190, ex parte). 
A more robust-looking plant than the preceding, Petioles 2-21 inches long. Blade of leaf 3 inches 
long. Flowers greenish, as far as could be seen from the young buds. Hermaphrodite flowers not seen. 
5. D. Vitiensis, Seem. (sp. uov,) ; petiolis apice 2-glandulosis; foliis glabris basi ovatis late 
3-lobis ovatis obtusis, supra viridibus, subtus pallidioribus, 3-5-nerviis; filis coronz exterioris lobis 
perigonii internis duplo brevioribus ; corona interiore truncata, ore dentato.—Viti Levu (Milne !). 
* D. cerulescens, Seem, in Bonplandia, vol. x. p. 866; glabra, petiolis 2-glandnlosis, foliis basi ovatis 
late 3-lobis, lobis indivisis triangularibus acutis, medio productiore, supra viridibus, subtus pallidioribus ; 
cirrhis simplieibus; floribus solitariis; pedunculis bracteolis 3 setiformibus instructis ; perigonil laciniis 
linearibus (cerulescentibus) ; corona interiore truncata ore minute undulato-crispa; autheris tortis; oyario 
subgloboso.—Tongan Islands (Capt. Cook! in Brit. Mus.). Blade of leaf 34 inches long; petiole 2 inches 
long. Outer segments of perigonium 13 inch long. Differs from D. adiantifolia and Barclayi in having 
glandulose petioles, from D, aurantia, coccinea, Herbertiana, and Baueriana in the colour of the flowers and 
the form of the leaves.
