16. E. 3illardierianum, Seringe ; — FI. N. Z. i. 61. Slender, simple 
or sparingly branched, glabrous or puberulous ; stems decumbent at the 
base; branches 6-18 in. high, terete, sparingly leafy. Leaves opposite and 
alternate, -|-1 in. long, sessile or very shortly petioled, linear-oblong or narrow 
ovate-oblong, obtuse, toothed, membranous, the upper gradually smaller. 
Flowers few towards the ends of the branches, rather large, f- in. diam., 
white or rosy ; peduncles usually longer than the leaves. Capsules 1^-3 in. 
long, pubescent. 
Mountainous parts of the Northern Island, Colenso. More common in the Middle 
Island, Lyall, etc. A most puzzling plant, and one of which I am almost incliued to refer 
the various forms to large-flowered states of telragonum, glabelium, atsinoides, junceum , 
and perhaps others. None of the New' Zealand specimens have leaves so sessile and semi- 
amplexicaul as those figured in the Tasmanian Flora : nor am I certain that either is the 
true plant of Seringe, which is very imperfectly described. 
17. E. pallidiflorum, Sol. ; — FI. N. Z. i. 61. The largest New Zea- 
land species. Stems erect, 1-3 ft. high, terete, as thick as a goose-quill, 
leafy, simple or branched, glabrous or puberulous. Leaves opposite, 2-4 in. 
long, sessile, semiainplexicaul, linear-lanceolate or -oblong, acute, jagged or 
toothed, glabrous. Flowers large, f-1 iu. diam., white or pale-pink, nume- 
rous towards the ends of the branches ; peduncles always shorter than the 
leaves. Capsule 2-3 in., hoary. — E. macranthum, Hook. f. Ic. PI. t. 297. 
Abundant in wet places throughout the islands, Banks and Solander, etc. A very distinct 
species, also common in Tasmania, at once recognized by its great size, long, sessile, narrow 
leaves and large flow'ers. 
Order XXX. PASSIFLOHE.®. 
Climbers (rarely erect shrubs), with lateral tendrils or 0. Leaves alternate, 
stipuled, entire or lobed. Flowers axillary, solitary or rarely racemose, usually 
hermaphrodite, often showy. — Calyx free ; tube short ; lobes 4 or 5 (rarely 3) 
long, imbricate. Petals 3-5, inserted at the base of the calyx, usually per- 
sistent (rarely 0), sometimes with a crown of filaments at their base. Stamens 
generally as many as the petals ; filaments often adnate to the stalk of the 
ovary. Ovary often stalked, 1-celled; styles 3-5 ; ovules many on 3-5-pa- 
rietal placentas. Fruit coriaceous or succulent, indehiscent or splitting be- 
tween the placentas. Seeds often arilled, exalbuminous ; cotyledons flat. 
A large tropical family, abounding in America, rarer in Asia. 
1. PASSIFLOHA, Linn. 
Flowers unisexual or hermaphrodite. — Calyx-lobes 4 or 5. Petals as many, 
with a ring of filaments at their base. Stamens 4 or 5 ; filaments quite adnate 
with the stalk of the ovary ; anthers versatile, those of the female flower, 
imperfect. Styles 2 or 3, with capitate stigmas. Fruit an indehiscent berry. 
A very large American genus, of which the few Old-World representatives are more or 
less dioecious and tetramerous. 
1. P. tetrandra. Banks and Sol. ; — FI. N. Z. i. 73. A lofty, glabrous 
climber, with slender, terete branches. Leaves 1^-4 in., petioled, lanceolate, 
acuminate, quite entire, eglandular; tendrils long and slender. Flowers | in.
