216 CI. CONVOLVULACES. (C. B. Clarke.) [ Ipomea. 
5. I. OVALIFOLIA, Chois. in DC. Prodr. ix. 357 ; said to be a native of India. There 
is no example thence; it is not = I. microphylla, Roth Nov. sp. 112, as Choisy 
supposed. 
6. I. SIDÆFOLIA, Chois. in DC. Prodr. ix. 372; is native in America, not in India. 
It is Convolvulus zeylanieus, Moon; Wall. Cat. 1379. 
7. I. TRIANTHA, Roem. 4 Sch. is perhaps I. sepiaria, Koen. (which see). 
6. LEPISTEMON, Blume. 
Character of Ipomea subgenus Euipomea, but filaments dilated at the base 
into 5 concave scales which arch over the ovary.—Species 4 (1 African, 3 
Asiatic). 
l. L. Wallichii, Chois. Convolv. Or. 61, and in DC. Prodr. ix. 348; 
hairy, leaves ovate-cordate acute entire or 3-lobed, cymes dense many-fld. short- 
peduncled, sepals elliptic-lanceolate acuminate, corolla % in. tubular narrower 1n 
the middle. L. flavescens, Wight Ic. t. 1362, not in Calc. Journ. Nat. Hist. 
t. 5, fig. 6, nor of Blume. Convolvulus cephalanthus, Wall. Cat. 1402. C. 
binectariferus, Wall. in Roxb, Fl. Ind. ed. Carey § Wall. ii. A7. Vallaris con- 
troversa, Spreng. Syst. cure post. 65. Ipomæa Wallichii, Steud. Nomencel. 
Bot. Nemodon sp., Griff. Notul. iv. 286. 
Assam, Kuasta Mrs, Sinner, and CacHar; ascending to 3000 ft.; Wallich, 
H.f.4 T. &c. Mercu; Griffith. 
Stems stout, scandent, fulvous-villous. Leaves 3-5 in., fulvous-hirsute on both 
surfaces; petiole 1-2 in. Peduncles 0-4 in.; cymes 10—30-fld.; bracts } in., linear- 
lanceolate, deciduous; pedicels many attaining 4 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, 
4-ovuled; style very short, and stamens in the lower part of the corolla-tube, stigmas 
2 subglobose. Capsule X in., ovoid, glabrous, 4-valved, 2-celled, normally 4-seeded. 
Seeds glabrous.—L. flavescens, Blume, a Javan species, has the sepals ovate subacute 
(not acuminate), the corolla rather shorter and wider at the base than in L. Wallichti. 
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 lobed. 
Peduncles axillary ; flowers few subcapitate or solitary ; bracts linear-lanceolate. 
acute, outer larger, enlarged in fruit. Corolla campanulate, yellowis 
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.
