238 coNVOLVULACEiE. [Ipomaa. 



lanceolate or narrow-oblong obtuse entire segments, 1 to 1£ in. long, con- 

 tracted at the base. Peduncles usually 1-flowered and shorter than the leaves. 

 Sepals ovate, the outermost about 3 lines long, the innermost twice as long. 

 Corolla near 2 inches long (pale pink ?), the tube dilated upwards into a broadly 

 campanulate shortly 5 -lobed limb. Ovary 2-celled. — /. pentadactylis, Chois. 

 in DC. Prod. ix. 385. 



Hongkong, Champion ; also in Burmah, and in tropical Australia. Seemann (Bot. Her. 

 p. 401) by some mistake refers this to the /. tuberculata, R. and S., of which there are some 

 specimens in Hance's collection from Hongkong gardens. The latter species, probably the 

 same as /". palmata, Forst., is not uncommon in tropical Africa and Asia, but I have seen no 

 wild specimens from Hongkong. It is readily distinguished in the dried state by the inner 

 sepals being about the length of the outer ones, instead of twice as long, besides minor differ- 

 ences in the shape of the leaf-segments and of the corolla. It has also the seeds bordered at 

 least with long hairs, and they are said to be glabrous in I. quinata. Our specimens of the 

 latter are not in fruit. 



2. I. pes-caprse, Swartz ; Chois. in DC. Prod. ix. 349. A glabrous per- 

 ennial, with long prostrate or creeping stems. Leaves on long petioles, oval, 

 obovate, or orbicular, broadly emarginate or very obtusely 2-lobed at the top, 

 2 to 3 in. long, rather thick, with nearly parallel oblique veins, the lower ones 

 converging at the base of the leaf. Peduncles in the upper axils 1- or few- 

 flowered. Sepals oval, obtuse, about 3 lines long, or the inner ones rather 

 longer. Corolla pink, campanulate, obscurely lobed, about 1^ in. long. Ovary 

 4-celled, or at least partially so, at the time of flowering. Capsule 2-celled, 

 oblong or ovoid, about -| in. long. Seeds hairy. 



On the seashore near Victoria, Hance. A common seacoast plant in almost all tropical 

 countries, but more especially in the Old World. 



3. I. filicaulis, Blume ; Chois. in DC. Prod. ix. 353. A. glabrous an- 

 nual, with slender prostrate or twining stems, and usually drying of a brown- 

 ish-black colour. Leaves on very short petioles, or almost sessile, linear-lan- 

 ceolate or linear, cordate or hastate, and often toothed at the base, 1 to \\ in. 

 long. Peduncles slender, longer than the leaves, 1- or 2 -flowered. Sepals 

 ovate-lanceolate or lanceolate-acuminate, about 3 lines long. Corolla yellowish- 

 white, ^ to f in. long. 



In sunny places, Hance. Frequent in tropical Asia and Africa, occurring also in tropical 

 Australia, and in some parts of tropical America. 



4. I. cymosa, Rcem. and Schult. ; Chois. in DC. Prod. ix. 371; Bot. 

 Reg. 1843, t. 24. A rather coarse twiner, glabrous or with the young shoots 

 more or less pubescent, usually turning dark brown in drying. Leaves stalked, 

 from narrow -ovate to oblong or almost lanceolate, shortly acuminate or obtuse, 

 2 to 3 in. long, the larger ones broadly cordate or almost sagittate at the base, 

 the narrow ones rounded at the base. Flowers pure white, or with a yellow 

 eye, in cymes of 6 to 12 or even more, rarely solitary or nearly so, on a short 

 rather thick common peduncle. Sepals 3 or 4 lines long, glabrous, coriaceous, 

 nearly equal in length. Corolla campanulate, above an inch long, scarcely 

 lobed, often hairy at the top. Ovary 2-celled. Seeds hairy. 



On the seashore, Hance. A common species in the greater part of India and the Archi- 

 pelago. 



5. I. bona-nox, Linn. A glabrous twiner often of great size. Leaves 

 on long petioles, broadly cordate-ovate, acuminate with a long point, 3 to
