f in. long, much dilated at the summit, with 2 diverging or divaricate lobes, 

 .otherwise entire, rigid, the margins revolute, glandular-scabrous above, scurfy- 

 scaly underneath. Flowers much larger than in any other r/iedalium, on very 

 short axillary pedicels with 2 or 3 leafy bracts. Calyx-lobes almost as long 

 as the tube. Petals 4 to 5 lines long*, densely scaly outside, lanceolate with 

 small inflexed tips, but the bud not seen. Longer stamens almost equalling the 

 petals, filaments flattened, glabrous; anthers minutely apiculate. Ovary 

 bearing a few scales. Pruit not seen.

Sepals 5, small, thin, free or slightly united. Petals 5, slightly imbricate 

 iu the bud. Disk none. Stamens 10, exserted; filaments filiform, glabrous 

 or ciliate at the base ; anthers tipped with a small gland. Carpels 2, dis- 

 tinct ; styles inserted above the middle and immediately united into one fili- 

 form style, with a minute stigma. Ovules 2, collateral, pendulous. Cocci 

 S-valved, rounded at the top and not beaked, the endocarp cartilaginous and 

 separating elastically. Seeds usually solitary. — Heath-like shrubs, glabrous 

 except scurfy scales on the young branches and under side of the leaves. 

 Leaves numerous, small. Flowers small, in dense terminal sessile heads, 

 with small leafy bracts at the base of tlfe outer ones. 



The geuus is limited to Australia^ and iniL;:ht be consItlcnMl as a section of Thehahum. 

 A peculiar habit, however, accompauied by a luarked ditfercncL; in the ovary, has induced me 

 to retain it aa a separate genus. 



Leaves very spreading, linear, smooth or roug;h, vvitb small ijlandular 



tubercles, the upper ones usually exceeding the flower-heads . . , 1, M, pauciflora.

'^ 1. M. pauciflora, Tnrcz, in BnIL Mosc. 1852, li. 107. BraucUes 

 rigid, lioary or almost tomentose with peltate friuged scales or stellate hairs. 

 Leaves spreading, linear, obtuse, 2 to 4 lines long, the margins revolute, so 

 as to be almost terete, coriaceous, glabrous and smooth above, or rough with 

 very smooth glanduhu tubercles, the under side scaly-tomentose but usually 

 concealed. Flower-heads about 3 lines diameter, sessile amongst the upper 

 leaves, which nsually exceed them. Sepals linear-hmccokte, transparent, 

 small, and easily overioolced. Petals scarcely 1^ lines long. Pihiments 

 glabrous or ciliate. Cocci small, rounded at the top, the valves coriaceous, 

 pitted but not wrinkled, and usually without scales. Seeds tuberculate.—
