140 LXXV, RUBIACEX. (J. D. Hooker.) [ Ivora. 
A shrub or small tree. Leaves 7-12 by 14-3) in., brownish when dry, mem- 
branous, points long and slender, above often glabrate, beneath hairy chiefly on tho 
15-20 pair of slender nerves, sometimes obscurely contracted above the cordate base 
(panduriform) ; stipules villous with very long filiform hairy points. Flowers sessile 
amongst filiform bracteoles, Calyw-teeth very slender. Corolla 4 in. diam.; lobes 
lanceolate, acuminate, Z the length of the tube. Filaments subulate. Stigma small, 
Fruit ellipsoid or globose, 3 in. long, glabrous, 
** Calyx-teeth longer and broader than the ovary, elliptic oblong or sub- 
orbicular ; cymes corymbiform. 
9. I. polyantha, Wight Ic. t. 1066; robust, glabrous except the villous 
or pubescent cymes, leaves large sessile or short-petioled obovate elliptic-oblong 
or -lanceolate acuminate coriaceous, cymes subsessile corymbiform contracted 
or open very many-flowered branches robust, calyx-lobes ovate-lanceolate very 
much longer and larger than the ovary, corolla glabrous, tube slender 4-1} in.,

WESTERN PENINSULA ; on the Ghats from the Conean to Cochin, Wight, Law, Ee, 
Shrubby, branches robust. Leaves 6-12 by 23-5 in.; pale greenish when dry, 
narrowed to the short stout petiole; stipules broad with long euspidate poiuts. 
Cymes either collected into a globose sessile head or more open and 4 by 5 in. long 
and broad; branches suberect, sometimes white with dense woolly spreading hair; 
bracts and bracteoles oblong, acute, membranous, caducous; flowers sessile. Calya 
sometimes J in. long, pubescent, lobes like the braeteoles. Corolla % in. diam., quite 
glabrous. Filaments flattened, Stigma rather large, with stout recurved arms. 
fruit not seen.—The bracts and calyx are very different from those of any congener, 
10. I. Kingstoni, Hook. f.; glabrous, branches and leaves above 
shining, leaves petioled elongate oblong or oblanceolate obtusely acuminate 
membranous, cymes sessile between two small leaves corymbiform contracted 
dense-flowered, branches short and stout puberulous, calyx-teeth membranous 
glabrous almost orbieular larger than the ovar , corolla-tube 1-1} in. very 
slender, lobes obovate obtuse, mouth naked. 
Maracca, Griffith (Kew Distrib. 2996). 
Branches as thick as a duck's quill, black, smooth, and polished when dry, inter- 
nodes long. Leaves 7-12 by 21-35 in. pale brown when dry, deflexed in flower, 
erect in the fruit, base acute; nerves slender, 15-20 pair; petiole l in, black; 
stipules short, closely appressed, apiculate. Cymes 4 in. diam., very deuse-flowered ; 
bracts and bracteoles broadly elliptic, coriaceous, deciduous, Calyx X in. long, glabrous. 
Corolla red ?, limb 1 in. diam. Stigma small, entire or notched. Filaments flattened. 
Fruit 5 in. long, globose or obliquely ovoid, crowned by the broad calyx-lobes.— The 
membranous leaves, stout short eyme-branches and the ealyx, afford good characters. 
It is clearly allied to Z. acuminata. Mr. Kingston, whose services this very hand- 
some species commemorates, was for some years an active assistant in the Herbarium 
department of Kew, 
ll. I. merguensis, Mook. f.; glabrous, very robust, leaves large 
obovate or oblong-obovate abruptly acuminate opaque coriaceous, cymes sessile. 
corymbiform globose densely many-flowered excessively branched from the 
very base, calyx-teeth puberulous elliptic longer than the ovary, corolla-tube- 
$ in. slender, lobes obovate or oblong obtuse, mouth nearly naked. 
Tenassertm ; Mergui, Griffith (Kew Distrib. 3003). 
A low shrub; branches stout, cylindrie, grey and opaque when dry. Leaves 7-12 
by 24-5 in., pale when dry and quite dull, narrowed into a short stout petiole ; stipules 
very short, coriaceous, apiculate. Cymes 3-4 in. diam.; branches quite hidden by 
the flowers ; bracts broad, deciduous; flowers odorous, white or pale pink with a red
