Nircumni and Suzvacuerry Hrs, Wight, Ae, 
Rigid; stems 8-18 in., terete. Leaves 2-3 by 3 in., rigidly coriaceous, pale brown 
when dry, complicate ; stipules erect, triangular-lanceolate, often quite entire. Cyme- 
branches puberulous or glabrous. Fruits apparently angled, somewhat laterally com- 
pressed, shortly pedicelled, as broad as long. 
5. X. brachycarpa, Br. in Wall. Cat. 821; more or less pubescent, 
stem with 2 lines of pubescence, leaves sessile linear-oblong obtuse, stipules 
entire or 3- or more-cleft, cymes open or capitate, fruits short didymous trun- 
cate. K. macrocarpa, Kurz in Journ. As. Soc. 1877, ii. 198. K. levis, DC.

An erect strict herb, 2.4 ft., internodes long; stem slender or robust; more or 
less hairy or glabrate, with always 2 more or less distinct lines of pubescence. Leaves 
2-4 by 1-2 in. usually quite sessile and minutely pubescent on the margins and 
nerves beneath, more rarely elsewhere, base acute or rounded, pubescence of midrib 
continued down the stem; stipules pubescent, upper often entire. Cymes, if branched, 
main branches pubescent in 2 lines, the smaller puberulous; when capitate often 
tomentose; flowers small, Calyx-teeth very small, obtuse, one larger. Fruit as in 
K. Wightiana.—I suspect this to be Roxburgh's Sp. levis; it is the only “interior of 
Bengal” plant at all answering to his description and drawing, from which it differs 
in the hairiness and large flowers. The Nipal and Bengal specimens have open 
cymes, the Kumaon ones globose terminal and sessile axillary heads, like Hedyotis ; 
the Pegu ones have long braehiato branches with trichotomous terminal peduncles 
bearing capitate cymes at their ends. 
tt One or two calyx-lobes in fruit much elongate, subulate. 
6. K. plantaginea, Wall. Pl. As. Rar. 27, t. 52; Cat. 818; hirsute, 
subscapose, leaves sessile linear-oblong obtuse or subacute, stipular bristles very 
short or 0, flowers capitate, fruits racemose, mericarps keeled with 1 or 2 
elongate calyx-teeth. DC. Prodr. iv. 570; Kurz in Journ As. Soc, 1877, ii. 138. 
Peco at Prome, Wallich; rare and sporadic, Kurz. 
Rootstock thick, tortuous, woody, giving off short woody leafy branches, from 
which the very slender simple flower-bearing stems arise. Leaves on the stem 3-5 
by 1-2 in.; softly hairy on both surfaces, green when dry; stipules usually reduced 
to a truncate sheath. Flowering stems 10-16 in., softly hairy, each bearing one or 
two very distant pairs of small leaves 1 in. long, apparently without stipules, s aringly 
trichotomously branched at the tip, each branch bearing a head of flowe which 
elongates into a spike or raceme of distant fruits several inches long. Calya-teath 
subulate, one or two much elongate and exceeding the meriearps. Corolla 4 in. long, 
pale blue. Fruit (in Wallich’s figure) 3 in., apparently flattened, with keeled meri- 
carps, the elongated calyx-tooth often much exceeding the fruit. 
7. X. zeylanica, Linn.; DC. Prodr. iv. 569; glabrous or glabrate, 
leaves shortly petioled ovate or ovate- or oblong-lanceolate, stipules entire or 
with nearly glabrous bristles, flowers capitate or spicate, fruits spicate, mericarps 
dorsally rounded and keeled. Burm. Fl. Ind. t. 19, f. 2; A. Rich. in Mem.

Ceyrox ; common in the southern part of the island. 
A small leafy rigid annual?; stem erect or ascending, and branches terete, smooth 
and seabrid above. Leaves 1-2 by 4—4 in., narrowed at both ends, obtuse or sub- 
acute, margins recurved. Spikes and flowers glabrate or hispid, when fruiting some- 
times 4 in. long and quite simple. Corolla-tube very slender. Fruit 4; in., broadly 
ovoid, the long ealyx-tooth equalling the merienrp, glabrous,
