referring it to Nasturtium. Whether the above-incutioned throe species 

 should also be transferred to Nasturtium is not easy to decide, as there 

 are differences in habit and in the shape and structure of the pod whicli 

 appear to be of considerable importance. Possibly they should form a 

 separate genus, in which case the Australian C. rndicata should be associated 

 with them. A step of that kind, however, involves an examination of the 

 characters of most of the genera constituting the tribe Arabidae, and is 

 preferably left in the hands of some systeniatist who is able to consult the 

 great herbaria and libraries of Europe. In the meantime it appears best to 

 place the species with C. stj/los(( in Nasturtium. They will then stand as

Lepidium tenuicaule T. Kirk. 



A dwarf form of this plant, which I have elsewhere described under the 

 name of variet}'^ minor, has been collected by Mr. B. C. Astun at Titahi Bay, 

 near Wellington. This is the first record for the species in the North Island. 



IV. ViOLACEAK. 



Melicytus micranthus Hook. f. 



In the Manual I have given the Bay of Islands as the northern limit of 

 this species ; but both Mr. Carse and Mr. R. H. Mattheivs inform me that 

 it occurs in several localities near Kaitaia, in Mangonui County. 



\. PiTTOSPORACRAE. 



Pittosporum tenuifolium Banks & Soland. 



Variegated forms of this species and of P. em/enioides A. Cunn. are now 

 frequently seen in cultivation.

Mr. A. W. Roberts, of Ranfurly, Otago, sends me a yellow-flowered 

 variety. The ordinary colour, to which I have never previously seen any 

 exception, is a pale cream. Both Mr. Roberts, and 3Ir. Mclntyrc, of
