published M. perpmilla, Hook, fil., and M. difusa, described 

 below, in its diffuse, much branched habit and short peduncles in 

 the upper axils ; but these foxir species diifer too much in their 

 leaves and calyx to be united into one. M. montana, Hook, ill., 

 another new species, has also a similar habit, but the flowers appear 

 termmal, and the capsule is of a very singular shape, something 

 hke that of the broad-fruited Veronicas, but with two styles at the 

 external angles instead of one in the middle. M. serpyllifolia, Br., 

 01 which I have only seen small flowering specimens, is very much 

 uke M. montana, but comes from a very different locality, and I 

 have not been able to ascertain the structure of its flowers. Jf, 

 alsinoides, Br., is a little annual near M. indica, but with broader 

 leaves chiefly in the lower part of the stem and longer slender 

 peduncles. Some specimens gathered by Bidwill at "Wide Bay 

 appear to belong to a slight variety somewhat hairy in the lower 

 part of the stem and leaves. The species described below as Jf. 

 , l<svu diflfers in the shape of the corolla. M, pygmcea, Br., is very 

 I % slender with the leaves all radical. It has aU the appearance of 



the small specimens of M. nudicauUs, and may possible prove to

be specifically identical, in which case Brovm's name, as the oldest, 



should he adopted. M. paludosa, Br., is also near alsinoides, but 



IS much branched with narrow leaves. M. ramosa, Br., and larici- 



folia, Br., are very distinct little annuals, with very narrow leaves 



f J ^^^ ^^^^ ^™^^ flowers, differing from each other chiefly in the 



shape of the corolla. M. phascoides, Br., is certainly the smaUest 

 of the genus ; the whole plant in full flower is scarcely more than 



a quarter of an inch high . "' / 



The commonest of the Port Jackson species in our herbaria, 

 distributed by Sieber as M.prolifera, n. 170, and pubHshed by Presl 

 "nder the name of M. hirsuta, is the M. polymorpla, Br., a species 

 varying much in hairiness, and running quite into the M. canes- 

 <•««*, Br. Among the numerous specimens I have seen from 

 various collections, there are some which might be equally well 

 determined to be M. squarrosa, Br., M. cinerascens, Br., or M. 

 Sieberi, DC, of none of which I have seen authentic specimens, 

 but a careful examination of which would, I have little doubt, 

 «how the propriety of uniting all these supposed species mto one.
