The rounded cymes, and numerous long subpersistent bracteoles, are good charac- 
ters for the species. Leaves 3-4 in., usually ovate or ovate-lanceolate, base acute, 
very membranous ; petiole slender. — Cyme-peduncles 1-} in., longer in fruit. Corolla: 
3 in. long, cylindric, lobes narrow. Capsules crowded, } in. diam. 
Var. ?Johnsoni; corolla narrower and longer % in. puberulous. —Cochin, John- 
son. 
Van. ? hirsutior, Wight mss. ; branches petioles and cymes densely tomentose.— 
Nilgherry Mts., Gardner.—I have seen neither flower nor fruit of this. 
ll. O. gracilis, Kurz in Journ. As. Soc. 1872, ii. 311; annual, erect, 
perfectly glabrous, leaves lanceolate with very long slender points, cyme long- 
peduncled, branches slender, bracteoles subulate, calyx-teeth minute, corolla-tube 
4 in. terete glabrous, 
TzNassERIM, Kurz; Birma, Brandis. 
I have seen a single specimen only. It is at once distinguished by the very long 
slender points of the membranous leaves, which are 5-9 in. long and rather oblique. 
12. O. radicans, Gardn. in Thw. Enum. 139; stems densely tufted

small few-flowered contracted, bracteoles few subulate, calyx-teeth subulate, 
corolla small, lobes short keeled on the back. 
Cryton ; Central Province, Gardner, Thwaites. 
Stems flexuous, a foot long, rooting at every node. Leaves 1-1 in. diam. Me- 
peduncles usually shorter than the leaves, but sometimes longer. Corolla &-1 in. long. 
Fruit not seen. 
13. O. oppositiflora, Hook. f.; stem erect woody and petioles leaf- 
nerves beneath and peduncle appressedly rusty-pubescent, leaves ovate-lanceolate 
acute glabrous rather rigid, stipules subulate, cymes terminal and opposite in the 
leaf-axils corymbose many-flowered, bracteoles minute or 0, calyx-teeth lanceolate 
obtuse, corolla 4 in. glabrous within and without tubular 5-angled, lobes oblong 
obtuse keeled.

Stem rigid, scabrid, 1-2 ft. Leaves 2-3 in.; petiole slender. Cymes often in the 
axils of all the 3-5 upper pairs of leaves, 1-1 in. diam. ; peduncles slender, im: 
branches erect; flowers numerous, slender, erect.—A very remarkable species, the 
only one with opposite cymes, 
** Bracteoles very slender, persistent or subpersistent. Corolla an inch or more

Tue Carnatic; Shevagherry hills, Wight. 
An erect undershrub. Leaves 5-7 in., membranous, almost caudate-acuminate.
