874 Scrophulariaceae. 
501. (9.) Peplidium Delile. 
Calyx tubular, 5-angled, 5-toothed or shortly 5-lobed. Corolla 
with a short tube and 5 nearly equal lobes. Stamens 2, the fila- 
ments somewhat dilated at the base; anthers 1-celled (by the con- 
fluence of 2 divaricate cells?). Ovary completely 2-celled. Style 
short, dilated upwards into a broad spathulate lamina curved over 
the stamens. Capsule globular or ovoid, indehiscent or irregularly 
bursting (or sometimes 4-valved?). — Small creeping or prostrate 
herbs. Leaves opposite. Flowers very small, axillary, without bracteoles. 
The genus is limited to 2 Australian species, of which one is widely 
diffused over the warmer regions of Asia and Africa. The genus ought, 
perhaps, to be reunited with Microcarpaea, in which Smith had placed the 
common species.

— For other synonymy see Benth in DC. Prodrom. X, p. 422. — A 
dwarf prostrate glabrous plant, creeping and rooting at the nodes, 
sometimes forming dense tufts of 5 or 8 cm diameter, sometimes 
spreading to a considerable extent. Leaves ovate obovate or orbi- 
cular, obtuse, entire, contracted into a short petiole, rather thick 
especially when small, 5—10 mm long or rarely rather larger (in 
very wet situations), the short petioles of each pair connected by 
their membranous margins. Flowers sessile or nearly so in the 
axils. Calyx scarcely above 2,5 cm at the time of flowering, with 
5 prominent angles or folds and membranous between them, the 
teeth short and obtuse. Corolla-tube rather shorter than the calyx, 
the lobes very short and rounded. Filaments rather thick, especially 
towards the base, angulary incurved. Capsule globular, large for 
the plant, very obtuse, enclosed in the distended calyx, about 2'/, mm 
diameter, membranous and indehiscent or at length bursting irre- 
gularly towards the base.

The species extends over the greater part of tropical and subtropical 
Asia and Africa. 
502. (10.) Limosella Linn.
