5TH Dxc., 1911. Mr. KE. Cheel (President) in the chair. 
There were present about 54 members. Mr. Nichols, Miss 
Clarice Pickering, and Mr. Beckford were elected members. 
Mr. W. Mervyn Carne delivered a lecture on ‘Botany 
through the Camera.’’ Mr. Carne lectured under extreme diffi- 
culties, being very unwell, and was only able to deliver a part 
of his lecture. This, however, proved so interesting that tho 
meeting unanimously requested him to repeat the lecture at 
a future date. A paper by Mr. Cheel, entitled ‘‘Notes on 
the Effects of Artificial Light on Deciduous Trees’? fol- 
lowed. This very interesting paper is printed in full in the 
present. issue. 
EXCURSION TO CENTENNIAL PARK. 
On Saturday afternoon, 7th October, the members went 
to the Centennial Park, chiefly to collect grasses, which are 
very plentiful there, and also to inspect the Native Flora 
Plantation, on the invitation of the overseer (Mr. J. Dawes). 
There was a large number of members present, who were led 
by the President, Mr. E. Cheel, through the flats where the 
native flora has been left undisturbed. The season was rather 
too early for grasses, but still a few species were collected 
including Poa annua, P. pratensis (Kentucky Blue Grass), 
Bromus umoloides (Prairie Grass), Holcus lanatus (York- 
shire Fog or Soft Grass), Briza minor (Small Shivery or 
Quaking Grass), Anthoxanthum odoratum (Scented Vernal 
Grass), as well as Cynodon dactylon (Couch Grass), and 
Stenotaphrum Americanum (Buffalo Grass), which make up 
the turf or lawns throughout the park. 
In addition to the grasses, the members were delighted 
to find a good number of species of typical coastal plants, 
including Vimmaria denudata, Sphaerolobium vimincum, 
Bossiaea ensata, Dillwynia floribunda, Drosera binata, Am- 
pera spartioides, Stypandra glauca, Triglochin procera and 
Heleocharis sphacelata, the last-mentioned being a great pest 
in the dams. 
After having spent nearly an hour in watching the mem- 
bers of the Aquarium Society (who also visited the park in 
search of aquatic life) as well as collecting specimens of the 
native flora found in a wild state, the members were then 
shown through the Native Flora Plantation by Mr. J. Nichol, 
who is in charge of this section. Mr. Nichol explained the
