different genus from I. Bes-capric, it is very nearly allied to it, differing chiefly in the narrower, 
more fleshy, and less prominently veined leaf, and the spurious dissepiments usually, but not 
always, more perfect and more permanent in the fruit Grisebaeh (FI. Brit. W. Ind. 471) places 
it in a section with glabrous seeds, but I have always found them very woolly in American as 
well as in African and European specimens. — Benth. 
20. I. reptans (creeping), Poir.; Chois, in DC. Prod. ix. 349 ; Benth. FI. 
Austr. iv. 4z0. A glabrous perennial, with long, prostrate, trailing or floating 
and hollow steins, often rooting at the nodes and sometimes bearing short 
ascending branches. Leaves on long petioles, from ovate to linear-lanceolate, 
acuminate, always cordate or hastate at the base, the angles rounded or produced 
into broad or narrow acute auricles, the leaf usually 2 to 4in. long, but rarely on 
the smaller branches a few small ovate-cordate and obtuse ones. Peduncles 1 or 
few-flowered. Sepals rather obtuse, 8 to 4 lines long. Corolla not so broad as 
in the two preceding species, more tubular at the base, pink-purplish or white, 
about ljin. long. Filaments hairy at the base. Ovary 2-celled. Capsule 
globular, coriaceous, apparently indehiscent or bursting irregularly. Seeds 
large, woolly, often reduced to 2. — I. aquatica, Forsk.; Clarke in Hook. FI. Brit. 
Ind. iv. 210 ; Rumph. Herb. Amb. v. t 155, fig. i., Rheede, Hort. Mai. xi., t. 52. 
Hab.: Flinders River, Sutherland; Cape River, Boicman. 
The species is found in marshy or wet sandy places, or floating in water, in many parts of 
tropical Asia and Africa. 
21 . I. graminea (leaves grass-like), Ft. Br. Prod. 485 ; Benth. FI. A nstr. iv. 421 ' 
A slender, glabrous twiner. Leaves on short petioles, linear-lanceolate or linear, 
entire, 4 to 8in. long. Peduncles 1 -flowered, A to ljin. long (including the 
pedicel), with very small distant bracts. Sepals oblong, obtuse, Jin. long or 
rather more, the outermost one shorter. Corolla 2J to 3in. long, contracted into 
a slender tube. — Chois, in DC. Prod. ix. 367 ; Convolvulus tjramineus , Spreng.

Hab.: Recorded for Queensland by F. v. Mueller. 
22. I. velutina (velvety), Ii. Br. Prod. 485 ; Benth. FI. Austr. iv. 421. 
A tall twiner, apparently woody at the base, softly velvety-pubescent or villous all 
over, the hairs usually reflexed on the branches, often silky on the leaves. 
Leaves petiolate, broadly ovate-cordate, obtuse or shortly acuminate, entire, 
2 to 4in. long. Peduncles about as long as the petioles or sometimes longer, 
bearing a dichotomous cyme of several large flowers, rarely reduced to a single 
flower on the side branches. Bracts very deciduous or none. Sepals broad, very 
obtuse, glabrous or nearly so, 3 to 4 or even 5 lines long. Corolla fully 3in. 
long, contracted into a tube at the base. — Chois, in DC. Prod. ix. 369 ; Convolvulus 
velutinus, Spreng. Syst. i. 601.

23. I. abrupta (abrupt), II. Br. Prod. 485 ; Benth. FI. Austr. iv. 
421. A tall woody twiner, glabrous or nearly so. Leaves petiolate, cordate- 
ovate, obtusely acuminate or almost acute, entire, from 2 or 3in. long, to twice 
that size. Flowers large, in pedunculate cymes, rarely reduced on lateral 
branches to single flow r ers. Sepals obtuse, coriaceous, 3 to 4 or rarely 5 lines 
long. Corolla fully 3in. long, contracted into a tube at the base. Capsule 
globose, nearly lin. diameter. Seeds dark-brown, thinly-velvety. — Chois, in 
DC. Prod. ix. 870 ; Fragm. x. 112 ; Convolvulus abruptus, Spreng. Syst. i. 596.
