96 FLORA VITIENSIS. 
Orpo XLI. PASSIFLORACE:. 
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 is now 
generally adopted. In Polynesia the Order is represented by one species of Passiflora and seven species of 
Disemma. 
I. Disemma, Labill. Nov. Caled. 78. t. 79; Endl. Gen. n. 5100.  Perigonium tubo brevi, 
subtus sulcato, limbi 10-partiti lobis 2-seriatis, interioribus minoribus corollinis. Corona faucis 
duplex, exterior filamentosa, filis l-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; antherz 
2-loculares, oblongze, incumbentes, longitudinaliter dehiscentes. Ovarium longe stipitatum, 1-locu- 
lare. Ovulain placentis parietalibus tribus co, co-seriata, horizontalia, anatropa. -Styli 3, cylindrico- 
subclavati ; stigmata subcapitata. Bacca subglobosa, 2-locularis, intus pulposa, placentis parietalibus 
3. Semina oco, 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 1-floris, bracteis a flore remotis.— Passiflore sp., Forst. ; 
Murucuje sp., Lindl. Coll. t. 36. 
This genus is confined to New Holland and the Pacific 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. (?) Barclayi, Seem. (sp. nov.) ; petiolis eglandulosis; foliis glabris basi ovatis late 3-lobis, 
lobis oblongis v. obovatis obtusis mucronatis, medio productiore ; czt. 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 1213 inch long 14 inch 
broad. The natives of Taviuni, 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. nov.) ; petiolis medio 2-glandulosis; foliis glabris basi ovatis late 
3-lobis, lobis ovatis v. oblongis obtusis mucronatis, supra viridibus, subtus pallidioribus, 38-5-nerviis ; 
pedunculis apice 2-articulatis, 2-3-bracteatis, bracteis setaceis; floribus masculis 4-meris.—Taviuni, 
in woods (Seemann! n. 190, ex parte). à 
A more robust-looking plant than the preceding. Petioles 2-23 inches long. Blade of leaf 3 inches 
long. Flowers greenish, as far as could be seen from the young buds. Hermaphrodite flowers not seen. 
3. D. Vitiensis, Seem. (sp. nov.); 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. 366; glabra, petiolis 2-glandulosis, foliis basi ovatis 
late 3-lobis, lobis indivisis triangularibus acutis, medio productiore, supra viridibus, subtus pallidioribus ; 
cirrhis simplicibus ; floribus solitariis; pedunculis bracteolis 3 setiformibus instructis; perigonii laciniis 
littearibus (czrulescentibus) ; corona interiore truncata ore minute undulato-crispa ; antheris tortis; ovario 
subgloboso.— Tongan Islands (Capt. Cook! in Brit. Mus.). Blade of leaf 31 inches long ; petiole 23 inches 
long. Outer segments of perigonium 1} 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.
