published M. perpusilla, Hook, fil., and M. diffusa, described 

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

 the upper axils ; but these four species differ too much in their 

 leaves and calyx to be united into one. M. niontana, Hook, fil., 

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

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

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

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

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

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

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

 alsinoides, Br., is a little annual near 31. 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 M. 

 Icevis differs in the shape of the corolla. M. pygmcea, Br., is very 

 slender with the leaves all radical. It has all the appearance of 

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

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

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

 is much branched with narrow leaves. M. raniosa, Br., and larici- 

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

 and very small flowers, differing from each other chiefly in the 

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

 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 published by Presl 

 under the name of M. hirsuta, is the M. polymorpha, Br., a species 

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

 cens, 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, 

 show the propriety of uniting all these supposed species into one. 



8. Polypbemum, Linn. 

 This genus, referred by the elder DeCandolle to Bubiacece, by 

 his son to Loganiacece, and by myself to Scrophularinece, must 

 accompany Logania and Buddleia, of which it has the aestivation
