66 LXXV. RUBIACE®S. (J. D. Hooker.) [ Oldenlandia. 
Not uncommon in the Dass of Innia from Rohilkund southwards and eastwards, 
but local. East Benoar, Griffith (Kew Distrib. 2912). CHITTAGONG, C. B. Clarke. 
Deccan not uncommon. (Not found yet in East Himalaya, Assam, the Khasia or 
Malay Peninsula).—-Distrin. Java. 
A diffuse flaccid herb; branches 2-3 in. Leaves 3-5 in.— The large calyx-teeth 
well distinguish this from any of the foregoing species. The tissues are sometimes 
full of raphides, as in some states of O. corymbosa. 
** Peduncles from the upper axils chiefly, many; lowered,

5. O. umbellata, Linn; DC. Prodr. iv. 425; annual, diffuse, glabrous 
or scaberulous, leaves often fascicled linear flat or almost acicular with recurved 
margins acute nerveless, peduncles in the upper axils stout 3-many-flowered, 
pedicels short, calyx-teeth a little shorter than the corolla-tube subulate, capsule 
didymous, crown low. Roxb. Cor. JN t.3; Fl. Ind. i. 421. O. puberula, G. Don

—Distris. N. Birma, Kurz. 
Stem woody, much branched from the base. Leaves 1-1 in., spreading or recurved. 
Cymes sometimes sessile and terminal. Capsules much as in O. corymbosa. 
6. O. Wightii, Hook. f.; perennial, scabrid, stem woody flexuous, 
branches rigid diffuse leafy, leaves squarrose linear-lanceolate acuminate, 
margins revolute, peduncles chiefly in the upper axils strict with terminal 
capitate cymes, calyx-teeth triangular-lanceolate pungent equalling the broad 
hemispheric didymous capsule. 
Western PrxixsuLA, Herb. Wight (Kew Distrib. 1511). 
Stems creeping in red soil or prostrate, several inches long; branches 4-6 in., 
tufted, erect or ascending. Leaves 3-1 in., sessile, pungent, scabrid on both surfaces ; 
stipules short, bristly. Peduncles usually exceeding the leaves, stout, seabrid. Heads 
4 in. diam. ; flowers sessile. Capsules large, seabrid, with a broad low crown and 
long spreading teeth.—This approaches a Hedyotis of the section Scleromitrion, but 
the foliage is not that of the majority of that group, and the form of the capsule and 
distant calyx-teeth well distinguish it. 
*** Flowers sessile, chiefly in the upper axis, solitary or crowded ; corolla 
rotate. (See also 2. O. diffusa.) . 
7. O. trinervia, Retz Obs. iv. 23; annual, glabrous or hairy, branched 
low diffuse leafy, leaves small subsessile ovate elliptic or orbicular, nerves 
distinct, flowers solitary or clustered in the axils sessile or subsessile) calyx- 
teeth very short equalling the rotate corolla, capsule small didymous' hairy 
crown low. O. repens, Burm. Fl. Ind. t. 15, f. 2? Hedyotis trinervia, TF.
