5. I. OVALIFOLIA, Chois. in DC. Prodr. ix. 357 ; said to be a native of India. There 

 is no example thence; it is not = /. microphylla, Eoth Nov. sp. 112, as Choisy 

 supposed. 



6. I. SID^FOLIA, Chois. in DC. Prodr. ix. 372 ; is native in America, not in India. 

 It is Convolvulus zeylanicus, Moon; Wall. Cat. 1379. 



7. I. TRIANTHA, Eoem. $ Sch. is perhaps I. sepiaria, Koen. (which see). 



6. LEFISTE1TCON, Blume. 



Character of Ipomcea subgenus Euipomcea, but filaments dilated at the base 

 into 5 concave scales which arch over the ovary. Species 4 (1 African, 3 

 Asiatic). 



1. Zi. Wallichii, Chois. Convolv. Or. 61, and in DC. Prodr. ix. 348; 



hairy, leaves ovate-cordate acute entire or 3-lobed, cymes dense many-fid, short- 

 peduncled, sepals elliptic-lanceolate acuminate, corolla in. tubular narrower in 

 the middle. L. flavescens, Wight Ic. t. 1362, not in Cole. Journ. Nat. Hist.

ASSAM, KHASIA MTS., SILHBT, and CACHAB ; ascending to 3000 ft. ; Wallich, 

 H.f.$T.,&c. MERGTJI; Griffith. 



Stems stout, scandent, fulvous- villous. Leaves 3-5 in., fulvous-hirsute on both 

 surfaces; petiole 1-2 in. Peduncles 0- in.; cymes 10-30-fld. ; bracts | in., linear- 

 lanceolate, deciduous ; pedicels many attaining ^ in. Sepals | in., patently fulvous- 

 hirsute, acuminate. Corolla slightly dilated, glassy at base ; tube hairy without ; 

 mouth shortly widely funnel-shaped, yellowish, white, or dull grey. Filaments short, 

 glabrous above ; basal process papillose ; anthers not twisted. Ovary 2-celled, 

 3:-ovuled; style very short, and stamens in the lower part of the corolla-tube, stigmas 

 2 subglobose. Capsule J in., ovoid, glabrous, 4-valved, 2-celled, normally 4-seeded. 

 Seeds glabrous. L. flavescens, Blume, a Javau species, has the sepals ovate subacute 

 (not acuminate), the corolla rather shorter and wider at the base than in L. Wallichii. 

 A Lepistemon from Borneo and the Philippines has the cymes almost capitate, 

 densely grey strigose ; but these 3 Asiatic species might perhaps be considered vars. 

 of one. 



7. HEWITTIA, W. % A. 



A pubescent, twining herb. Leaves cordate, entire angular or Ibbed. 

 Peduncles axillary ; flowers few subcapitate or solitary ; bracts linear-lanceolate. 

 Sepals acute, outer larger, enlarged in fruit. Corolla campanulate, yellowish 

 with a purple eye ; limb 5-plaited. Stamens included ; filaments linear, bases 

 dilated. Ovary hirsute, 1- (or imperfectly 2-), celled, 4-ovuled ; style filiform, 

 stigmatic lobes 2 ovate-oblong. Capsule globose, 4-valved, 1-celled, normally 

 4-seeded. Seeds glabrous.
