much longer than the anthers, smooth ; ovary strongly com- 

 pressed, constantly two-celled, with one ovule in each cell ; fruit 

 very small, scarcely half exserted, obcordate or truncate -roundish, 

 rather prominently two-edged, two-seeded ; pericarp very thin, 

 not succulent. 



On rivulets near Mount Dromedary ; Miss Mary Bate. 



A shrub, attaining a height of about 5 feet, branchlets smooth, 

 slightly viscid. Leaves flat, when well developed 3 to 4 inches 

 long, i to J inch broad, copiously and almost transparently 

 dotted; gradually attenuated into the narrow acute summit. 

 Stalklets of flowers 1 J to 3 lines long. Segments of calyx hardly 

 exceeding the length of 1 line. Corolla outside more or less 

 rosy-purplish ; its lobes measuring scarcely £ inch, the tube 

 about as long. Stamens four. Style setaceous, glabrous, rather 

 above 1 line long. Fruit measuring hardly more than £ inch, 

 somewhat turgid, very compressed at the margin. Seeds oblong- 

 ellipsoid, pendent from the roof of the cell. 



This handsome and evidently rare species is in foliage very 

 much like the genuine West-Australian If. serratum, but in fruit 

 very different, and comes thus far near If. florilundum ; indeed 

 it belongs to the series, which on carpologic characteristics was 

 generically separated by Alphonse de Candolle as Disoon, of 

 which subgenus only If.platijcarpum and M. florilundum are known 

 from Eastern Australia, both very different in foliage from the 

 new congener now recorded. Irrespective of the difference of 

 the very narrow leaves, M. florilundum has rather acute lobes of 

 the corolla, the tube of which surpasses considerably the length 

 of the calyx, and the fruit is nearly twice as long as broad. 



If. platycarpum becomes a small tree, and is restricted to the 

 desert regions of South-Eastern Australia ; its leaves are smaller 

 and more rigid than those of If. Bateas, their serratures are more 

 distant and they occur only towards the upper end of the leaves, 

 the calyx has the shortness of that of M. florilundum, the corolla
