broad or narrow, the basal auricles rounded, with occasionally an acute tooth or 
angle on the outer side, the whole leaf 1 to 2in. long. Pedicels rather long, often 
above lin., solitary or few together on a very short common peduncle, with 
minute bracts. Sepals obtuse or mucronate, about 4 lines long, coriaceous but 
often with membranous margins. Corolla li to nearly 2in. long. Capsule 
depressed-globular, shorter than the calyx, not wrinkled. Seeds glabrous. —

25. I. gracilis (slender), It. Br. Prod. 484; Benth. FI. Austr. iv. 422. 
“ Almor-ira,” Palmer River, Both. A rather slender twiner, glabrous or 
scabrous-pubescent. Leaves on long petioles, lanceolate-hastate or triangular- 
cordate, acute, mostly 1 to 2in. long, the basal lobes or auricles usually acute 
long and divergent or curved inwards towards the end, but varying in breadth 
and sometimes but rarely almost obsuse. Peduncles, including the pedicel, 
as long as the petioles, bearing a single rather large white flower, the bracts very 
small. Sepals broadly lanceolate, acute or acuminate or rarely obtuse, 4 to 5 
lines long or 6 lines when in fruit. Corolla about 2in. long. Capsule globular, 
smooth, 5 to 6 lines diameter. Seeds shortly pubescent, with a tuft of longer 
hairs at the hilum.— Chois, in DC. Prod. ix. 870 ; Convolvulus rpacilis, Spreng.

26. I. sepiaria (found in hedges), Keen.; Chois, in DC. Prod. ix. 370 ; Benth. 
FI. Austr. iv. 422. A twiner, either quite glabrous or the stems hirsute with long 
spreading or reflexed hairs. Leaves petiolate, broadly cordate-ovate, obtuse or 
shortly and obtusely acuminate, the basal auricles rounded or angular, mostly 1 
to 3in. long. Peduncles rather rigid, longer than the petioles, bearing a dense 
cyme or cluster of 3 to 5 pink or white flowers on short pedicels. Bracts small, 
narrow, often persistent. Sepals ovate-lanceolate, acute or mucronate, varying 
from 2i to 4 lines in length, the outer ones often rugose. Corolla about 1+in. 
long. Capsule globular, somewhat depressed, smooth. Seeds glabrous or furred.

The species is dispersed over E. India and the Eastern Archipelago. 
27. I. Muelleri (after Baron Mueller), Benth. FI. Austr. 423. A glabrous 
rather slender twiner. Leaves on rather long petioles, very broadly cordate-ovate, 
obtuse, with rounded basal auricles, entire, 1 to 2in. long. Peduncles shorter 
or at length longer than the petioles, bearing 1 to 3 flowers on very short pedicels. 
Bracts very small. Sepals broad, obtuse or scarcely acuminate, 4 to 5 lines long. 
Corolla apparently pink, rather above lin. long. Capsule globular, smooth, as 
long as the calyx. Seeds villous. 
Hab.: Boulia, Dr. IT. E. Roth: Cloncurry, F. v. Mueller. 
Evidently nearly allied to l. sepiaria, but the flowers are smaller and the seeds villous. — Benth. 
28. I. cymosa (flowers ^n cymes), Ram. and Sehult.; Chois, in DC. Prod. 
ix. 371 ; Benth. FI. Austr. iv. 423. A rather coarse twiner, glabrous or softly 
pubescent, usually turning dark brown in drying. Leaves petiolate, from ovate 
to oblong or lanceolate, shortly acuminate or obtuse, the larger ones broadly 
cordate or almost sagittate, the narrow ones rounded at the base. Flowers of
