1. M. Uvedalise, Benth, in DC, Prod, x. 369. Apparently annual and 

 quite glabrous, the steins very slender and weak, slightly branched, under 1 

 ft. long, Kadical leaves rosulate, ovate, but very soon disappearing; stem- 

 leaves small and distant, linear-lanceolate, acute or scarcely ohtuse, entire, 

 stem-clasping, rarely exceeding \ in. Pedicels in the upper axils slender, I 

 to 2 in. long or more. Calyx 2 to 2^ lines long, the teeth very sranll. Co- 

 rolla about twice as long as'the calyx, pale blue with a yellow throat (&Zfl/^^. 

 MSS,), Capsule oblong, shorter tl^nn the calyx, the valves readily splittnig.

2. M. gracilis, R. Br. Prod. 4B9. Quite glabrous. Stems from a 

 perennial somewhat creeping rhizome, erect, usually about 6 in. and rarely in 

 the Australian specimens nearly 1 ft. high, not much branched except at the 

 base. Leaves liuear-oblong to oblong-lanceolate, obtuse, entire, in some 

 specimens attaining 1 in., but in others all under \ in. long. Pedicels some- 

 times scarcely longer than the leaves, but often attainiui? 1 to 2 in. Caly^ 

 about 1\ lines long, with short acute teeth. Corolla violet purple or blue, 

 the tube shortly exceeding the calyx or rarely half as long again, the lobes 

 very broad, those of the lower lip retuse, all minutely ciliolate. Capsule en-
