No one can examine the broken and fragmentary evidence 
we possess respecting the distribution of our native flora without 
granting that a wide field is open for future research. No doubt 
much preliminary and useful work has been done, considering 
the youth of the Colony, and that most of its inhabitants have 
of necessity to occupy themselves with more personal and press- 
ing matters than that of tracing the range of a plant, of finding 
out how high it ascends the mountains, or of ascertaining the 
physical character of the localities in which it grows. But a 
noteworthy difference exists between what is already recorded 
and what is required before it will be possible to compile a 
“ Cybele Nove Zealandiz ” similar in scope, and equal in point 
of detail, to the “Cybele Britannica” ot the late Mr. H. C. 
Watson. Material might, however, be more rapidly collected if 
our working botanists would from time to time publish in the 
JOURNAL OF SCIENCE, or elsewhere, notices of new or unpub- 
lished localities, using, of course, due care in the identification of 
the species. Probably this system, if once established, would 
soon lead to the formation of a Botanical Exchange Club, similar 
to the well-known institution of this name in England, which 
has so materially assisted in bringing the knowledge of plant- 
distribution in the British Isles to its present satisfactory condition. 
So far as I am aware, the plant-stations given below have 
not been previously published. With most of them I have been 
acquainted for years, and it is possible that some may also be 
known to other botanists, although I have no knowledge that 
this is the case. 
Pittosporum virgatum, Kirk.—Between Coromandel and Ken- 
nedy’s Bay; abundant. The other known localities are the 
Great Barrier Island and Whangaroa. 
Pittosporum kivku, Hook, f—Summit of Maungataniwha, 
Hokianga, alt. 2500ft.; the most northern habitat yet recorded. 
Hills to the north of the Pirongia Mountain; its southern limit 
so far as is at present ascertained. 
Pomaderris edgerleyi, Hook, f.—Bare hills along the Northern 
Wairoa River, from Te Koporu to Dargaville, and stretching 
across to the sea south of Maunganui Bluff (T.F.C.) Between 
Orewa and the Wade (Rev. J. Bates). The stations previously 
recorded for this local plant are :—Cape Colville Peninsula, from 
Tarara to Cabbage Bay ; Mount Manaia, Whangarei ; and the 
North Cape District. 
Discaria toumatou, Raoul.—Sandhills to the north of Port 
Waikato ; probably its extreme northern limit.
