Knozia.] LXXV. RUBIACEX. (J. D. Hooker.) 131 
8. K. platycarpa, Arn. Pugill. 26; hirsute or glabrate, leaves ovate 
linear-oblong -ovate or -lanceolate, stipular bristles many hairy, cymes with 
short crowded branches but lengthening much in fruit, mericarps dorsally flat- 
tened and deeply keeled. 
CzyroN; abundant in the central province, alt. 4-7000 ft. 
According to Thwaites a very variable species, of which he distinguishes the threo 
following forms, which look very unlike; all have short branched cymes and two 
forms of flowers, which are either hirsute glabrate or glabrous, and resemble those of 
K. zeylanica, but are often larger. 
Van. 1. platycarpa, Arn. l. ¢.; nearly glabrous, branches with two obscure lines 
of pubescence, leaves narrowly oblong-lanceolate ciliolate, stipular bristles short nearly 
glabrous.—Resembles in foliage K. zeylanica, and as the cyme branches frequently 
run out I suspect these species may prove the same. 
Var. 2. hirsuta, Thw. Enum. 152; hirsute or tomentose, leaves broader, stipular 
bristles longer and hirsute, cymes very dense, flowers larger usually very hirsute.— 
K. hirsuta, Arn. l. c. 
Van. 3, foliosa, Thw. l. e: hirsute or glabrate, branches very stout, leaves moro 
coriaceous broadly ovate, stipular bristles very rigid, large calycine lobe sometimes 
foliaceous. 
DOUBTFUL SPECIES. 
K. sumatrensis, DC. Prodr. iv. 569, from the Cirears ;—it is impossible to say to 
what this refers. Roxburgh’s Spermacoce sumatrensis (which is referred to it) is 
described as having the corolla with a broad gibbous tube, and a 2-valved capsule 
2-partible from the base; it is probably a Hedyotis. 
TRIBE IX. ALBERTEZ. 
62. OCTOTROPIS, Bedd. 
A glabrous shrub; branches slender. Leaves elliptic-lanceolate, caudate- 
acuminate, membranous; stipules triangular, persistent. Flowers in peduncled 
axillary or supra-axillary corymbose cymes. Calyx-tube turbinate, 5-toothed. 
Corolla campanulate, tube short, throat villous; lobes 5, ovate, acute, twisted 
in bud. Anthers 5, sessile on the mouth of the corolla, linear, cuspidate, base 
2-fid, exserted. Disk small. Ovary l-celled ; style stout, pubescent, 8-ribbed ; 
arms 2, short, acute, glabrous; ovules solitary or a pair pendulous from the top 
of the cell. Fruit ovoid, smooth, coriaceous, l-seeded. Seed oblong, pendu- 
lous. 
1. O. travancorica, Beddome Fi. Sylv. t. 927 ; For. Man. 184/12. 
TRAVANCORE, alt. 83-3500 ft. ; Shevagherry hills, Wight, Beddome. 
Leaves 34-6 in.; petiole } in. Peduncles capillary, half as long as the leaves ; 
cyme-branches opposite; bracts small; flowers 4 in. diam., shortly pedicelled, 2-brac- 
teolate.—A very singular genus, belonging to an otherwise exclusively African tribe, 
Octotropis is further unique in the Order, in haying a 1-celled ovary with 1 or 2 pen- 
dulous ovules. Specimens of this in Wight’s Herbarium are fastened on a sheet with 
a Canthium. 
TRIBE X. VANGUERIEZ. 
(PLECTRONIA, Linn. in part.) 
Unarmed or spinous shrubs, erect or climbing ; branches terete. Leaves op- 
posite; stipules connate. Flowers small, axillary, fascicled or in peduncled 
corymbose cymes, white or greenish, sometimes polygamous, Calyz-tube short ; 
limb very short, persistent or deciduous, 4-5-toothed. ^ Corolla-tube funncl-
