(d.) microphyllum — It was at first thought that L. Liver- 

 sidgei might be this variety, and was so named by us at 

 first, but a further investigation showed this determination 

 to be wrong. This variety is a robust shrub with stout, 

 divaricate or dichotomous branchlets with leaves drying a 

 light grey colour and the whole plant resembling somewhat 

 a small variety of L. Icevigatum with scattered leaves, a 

 marked contrast to the erect branches with very numerous 

 very fine slender filiform branchlets of this new species 

 which has also less numerous, more distant and differently 

 shaped leaves. 



(e) minutifolium, of F.v.M. — This is altogether a different 

 form from this new one, having distinctly channelled 

 recurved leaves, smaller and differently shaped to those of 

 L. Liversidgei. It has also stouter branchlets and never 

 the slender filiform ones of the latter species, and its leaves 

 are distinctly 3-nerved, whilst the flowers show good 

 characteristic differences, are much smaller, and the petals 

 being more deciduous. 



L. scoparium, Forst. and L. arachnoideum, Sm., have 

 each a glabrous calyx, and that is their only resemblance 

 to this species. 



Essential Oil. 



The lemon odour which this plant gave when the leaves 

 were crushed, was considered to be an indication of the 

 possible presence of citral, and as the results promised to be 

 of an interesting nature, a quantity of material was obtained 

 for distillation. The material was collected several days 

 before it reached the Museum, and the leaves had, by that 

 time, become so loosely attached to the stem that they 

 easily fell off when the twigs were shaken. The leaves of 

 this plant are very small, and as they so readily fall off it 

 would be desirable to distil the plant soon after collecting. 

 The twigs and woody portion were present in larger amount
