Calyx 4-lobed or rarely 3-lobed. Corolla usually campanulate, 4-lobed, 

 valvate in the bud. Stamens 4. Ovary 2-celled, with several ovules in each 

 cell. Style simple, but splitting at the base as the flowering advances. 

 Stigma entire or slightly 2-lobed. Capsule compressed, 3-lobed at the top, 

 surmounted usually by the split style, and opening along the inner edge of 

 the lobes. Seeds ovoid or globular. — Herbs, mostly annual. Leaves oppo-

The genus comprises a considerable number of Australian species, with three from tropical 

 Asia.

1. M. capillaris, Wall. ; Benth. in Journ. Linn. Soc. i. 93. A slender 

 erect annual, 3 to 6 in. high or rarely drawn up to near a foot, more or less 

 hairy at the base. Leaves collected in the lower part of the stem, but in 

 distinct pairs, oblong or lanceolate, 3 to 6 lines long, more or less hairy, the 

 upper ones at the branching of the inflorescence very few, small and bract- 

 like. Flowers few, in an iiTegular terminal umbel. Calyx-lobes acute, from 

 half as long to nearly as long as the corqlla-tube. Corolla usually about 2 

 lines long, bujt varying in size, narrow-campanulate. Style entire at the time 

 of flowering, but splitting at the base as the ovary enlarges. — M. malaccensis, 

 Wight, Ic. t. 1601. 



On roadsides and in stony places. Champion, ff^Uford. Dispersed, over various parts of 

 India from the Peninsula to Nepal and to Malacca. 



3. M. nudicaulis, ReHme.i Benth. in Journ. Linn. Soc. i. 93. Tins 

 may be only a variety of M. capillaris, although usually considered as distinct. 

 It is more slender, seldom above 4 in. high. Leaves all collected at the base 

 of the stem and rosulate, from obovate to oblong, 3 or 4 lines long; the 

 bracts at the base of the peduncles very minuiie. llbwers seldom above \\ 

 lines long. — M. cMnensiSi Griseb. in PI. Meyen. 51.
