HeDYOTIS LeSSERTIANA. (Arnt). Shrubby, glabrous, branches compressed, leaves oblongo-lanceolate acuminate 
petioled rigid, veins simple, very prominent beneath ; stipules, marcescent, lower ones sheathing tubular with a few teeth at the apex, 
upper ones triangular scariose; panicles corymbiform, peduncles elongate, pedicels shorter than the calyx ; calyx cupulate 4-toothed, 
corol without subpuberulous, villous in the jaws ; capsule oblong obovate dicoccous. Arnt. Pag. 22(339) — Walp. Rep. ll.p. 492.' 
Anamallay Mountains (higher ranges.) Ceylon 3,000 to 8.000 feet. A very variable plant in regard to the size of the leaves and 
the inflorescence, the latter being sometimes rather lax as in the plate aud in other forms densely conferted. Mr. Thwaites mentions four 
varieties from Ceylon, but says they merge insensibly into one another. 
PLATE No. NXXL 
HeDYOTIS ASPERA. (Fleyne). Annual erect simple or with a few straight simple erect branches, all over rough with 
minute points : leaves linear acuminated; stipules membranous, with 1-3 longish subulate points; cymes terminal long peduncled, 
usually of one short central branch and two longish lateral ones ; flowers usually in pairs, shortly pedicelled with or without a short 
partial peduncle, racemosely and rather distantly arranged along the branches of the cyme ; calyx-teeth approximated during flowering, 
iii fruit distant with the sinus wide ; corol long infundibuliform, anthers included ; capsule nearly globose, somewhat didymous truncated.

Anamallay Mountains, Dindigul hills, Arcot, Coimbatore and elsewhere. The plant figured is the mountain form (Anamallays 
4,000 feet) and is much larger flowered than the form abundant in the plains about Coimbatore. 
PLATE No. XXXII. 
HeDYOTIS HeYNEI. (Br.) Annual or biennial, erect or decumbent with erect branches, dichotomous glabrous, stems 
sometimes terete at the base above and the branches acutely 4-angled ; leaves linear or linear lanceolate ; stipules with several short 
bristles or often truncated and naked; pedicels slender 1-flowered axillary solitary or in pairs in the opposite or alternate axils, from 
shorter to a little longer than the leaves 4-8 times longer than the fruit; calyx segments in fruit distant with the sinus wide, from trian- 
gular-acuminated and small to oblong-lanceolate and elongated ; corol infundibuliform, anthers somewhat included ; capsule roundish- 
ovate gibbous at the base crustaceous, opening with a very elevated compressed widely dehiscent ridge across the apex, lips of the opening 
<erect, flowers bluish or white.— Br. in Wall. L. n. 867—1 V.A. Prod. £>.416;—H. herbacea, Willd. (not Linn .); Rheed. Mai.

Anamallay forests up to 3,000 feet and many other localities on the western side of the Presidency. Very similar to II. 
dichotoma, but a more delicate plant. 
PLATE No. XXXIII. 
HeDYOTIS NUDICAULIS. (VV. A.) Annual with a filiform root; leaves 4-5 all radical roundish ovate, slightly attenuated 
at the base, sessile sprinkled with short hairs particularly ou the margin and nerves underneath, scapes 2-3 slender scabrous from close short 
fuscous hairs, bearing each about the middle a lax corymbose spreading 3-4 chotomous panicle, pedicels bristle-shaped glabrous ; corolla 
with a very short tube bearded in the throat with white hairs ; capsule somewhat globose ; W. and A. prod, p, 416; IT. scapigera, Br. ?

PLATE XXXIY. 
HeDYOTIS CYMOSA. (Thw.) Shrubby erect (turning black in drying) ramuli slightly angled; leaves glabrous, shining, 
narrow lanceolate, acute at both ends, 2-3 inches long 3-7 lines broad,primary veins inconspicuous, stipules triangular with a longish acumi- 
nation carinate, glandularly dentate on the margin, cymes terminal, lax, puberulous, calyx glabrous, 4 partite, segments lanceolate acute 
at length recurved, corol externally glabrous, pilose in the jaws.— Thw. Bn. PI. Zey. p. 142. 
Ceylon, at an elevation of 1,000 feet. 
PLATE XXXV. 
HeDYOTIS GLABELLA. (Br. ?) Stems acutely 4-angled, glabrous except near the joints, leaves oblongo-lanceolate to linear 
lanceolate, short petioled, or subsessile, shining above but scabrous at and near the margin, at length often quite glabrous, margins often 
recurved, glabrous and pale colored beneath and veins often not visible ; stipules with about G filiform ciliated teeth nearly as lone; as 
the flowers; flowers solitary or in pairs in the axils of the leaves, calyx segments ciliate triangular, erect in flower and fruit, segments 
of the corol ciliated at the apex, stamens and style exserted; capsule oblong with 2 hard bony cocci indehiscent. Broivn in Wall.

Note. —Mr. Bentham separates Oldenlandia from Hedyotis on account of its loculicidal dehiscence. Of the above species, quadnlocularis, 
trinervia, cwruleu, aspera, Eeynei and nudicaulis. belong to Oldenlandia.
