DeNTELLA. : RUBIACEZE. 405 | 
: casionally also of the pedicels : tube of the corolla shortish, nearly cylindric: 
style protruded.— Wight ! cat. n. 1288. 
Closely allied, on account of the bracteas, to O. bracteolata, Br. in Wall. ! 
L. 6228 (0. Munghos var. Nepalensis, DC.), and O. rugosa, Wall.!; but 
both of these are herbaceous, and have the corolla twice or th rice as long as 
our species.

Stipules cohering with the petioles on both sides, and Moree! | with them a more - 
or less distinct sheath that is usually split into several bristles. egments of the co- 
rolla imbricated in ewstivation. Stamens 4 (except in Dentelia). 
XII. DENTELLA. Forst. ; Lam. ill. t. 118. : 
Calyx-tube globose: limb 5-cleft ; segments lanceolate, acute. Corolla in- 
fundibuliform ; tube 2-3 times longer than the limb of the calyx, slightly 
hairy on the inside near the base: limb 5-cleft, spreading ; segments ovate, 
acute, with an acute tooth on each side above the middle. Stamens 5: fila- 
ments very short, inserted a little above the base of the tube : anthers oblong, 
not reaching above the middle of the tube. Style very short. Stigmas 2, 
long, narrow-linear, slightly spreading. Capsule (or dry berry) scarcely de- 
hiscent, between globose and ovate, hirsutely villous, crowned with the per- 
manent limb of the calyx, 2-celled. Placentze fleshy, hemispherical, adnate 
to the middle of the dissepiment. Seeds numerous in each cell, minute, an- 
gled.—Herbaceous, annual, tufted, creeping plants, growing in wettish situa- 
tions, as on the banks of water-courses. Stems filiform, branched, glabrous. 
Leaves oblong, attenuated at the base, glabrous, or with the petioles ciliated 
at the base. Flowers white, small and very tender, axillary, solitary, alter- 
nate, very shortly pedicelled. 
D. erecta of Roth (nov. sp. p. 140), — alternate leaves, must obviously be re- 
moved from the family. Chamisso and Sch echtendal (in Linnea, 4. p. 151) describe 
it with the calyx free from the fruit, but donot mention the natural order to which 
it belongs: these specimens, however, are probably in a bad state, for in those be- 
fore us the ovary certainly coheres with the calyx. The plant is truly a species of 
Wahlenbergia (W. perotifolia, W. & A.), not noticed, so far as we can ascertain, by 
M. Alph. De Candolle, or by Dr Wallich, although sent to the latter by Dr Wight.

De Candolle mentions that Old. repens of Burman (fl. Ind. t. 15. f. 2), on 
the authority of his herbarium, is Peplis portula ; but although tbis be true of 
the specimen, we suspect, from the reference to Plukenet, and the locality, 
_ that the figure and specific character belongs to Hedyotis serpyllifolia, Poir. : 
Peplis Portula is not found in the Peninsula. 
XIII. HEDYOTIS. Linn.; Lam. ill. t. 62; Brown ; Wall. 
Calyx-tube ovate or globose: limb 4-toothed or 4-cleft, the teeth or seg- 
ments persistent, without smaller intermediate ones. Corolla somewhat re- 
_ gular, infundibuliform, tubular, or rotate, 4-cleft, the segments imbricated 
(not twisted) in estivation. Stamens 4, inserted into the mouth of the
