274 Transactions. — Botany. 



0. juncea extends inland from Palmerston South to the Lake District, 

 It grows chiefly in alluvial tracts, and not rarely in almost pure shingle. 

 Its specific name is a very appropriate one. 



C. kirkii I have gathered at Otepopo and in valleys of the Kock and 

 Pillar Bange near Hyde. Mr. Kirk's discovery of it in Cardrona Valley 

 shows that it has a wide range. No doubt it will ere long be found in other 

 intermediate stations. 



C. uniflora is reported from the Lower Waitaki Valley by Mr. Buchanan. 



C. compacta I have seen only in the Clutha Valley, between Lake Waka- 

 tipu and Clyde, where it is the commonest species. 



C. enysii (?) I believe grows on spurs of Mount Ida and near the Ewe- 

 burn Creek, but, as I have no specimens in my herbarium, this point must 

 remain for the present unsettled. 



I quite agree with Mr. Kirk's opinion that C. australis does not occur in 

 Otago. At any rate I have never gathered any form which I could refer to 

 this species, and I have collected assiduously. 



It is a characteristic of several New Zealand genera of plants that two 

 or more species often grow side by side in the same locality. This may be 

 well seen in the genera Coprosma, Olearia, Celmisia, Epilobium, and 

 Veronica, among others. It holds to a certain extent in Garmiclialia also. 



In the Maniototo Plain C. crassicaulis, C. odorata, and C. nana grow side 

 by side, while C. juncea and C. enysii (?) both grow in suitable localities in 

 the same district. Many a square mile could be selected there containing 

 all of the foregoing. So 0. odorata and 0. compacta grow side by side through- 

 out the area in which the latter is known to occur. 



Near Otepopo C. kirkii and C. flagelliformis flourish in the same locality, 

 the former being, however, much the rarer. 



Of the Otago species C. flagelliformis is the most isolated, and the widest 

 ranging. C. odorata and C. nana have also a wide range, chiefly in the 

 drier parts of the province. C. juncea stands next in extent of range, 

 though it does not in this respect surpass the much rarer C. kirkii. G. 

 crassicaulis, C. compacta, and G. enysii (?) are the most local and restricted in 

 their distribution. 



I think it probable that another new species of Carmiehcdia will be 

 found in Otago, as I have forms of a very distinct character which I cannot 

 refer to any described species. Ampler materials may enable me ere long 

 to throw more light on these anomalous specimens.
