THE AUSTRALIAN NATURALIST. 145 
- Some very fine specimens of Calvatia lilacina and Mycen= 
astrum corium, two species belonging to the ‘‘puff-ball’’ or 
Lycoperdaceae family, were also collected, as well as a few 
Specimens of Bovistella aspera. This latter species is also 
one of the ‘‘puff-ball’’ family, and very closely resembles the 
genus Lycoperdon or true ‘‘pufi-ball,’’ which are popularly 
called “‘Devil’s Chimney Pots,’? on account of the spores 
coming out of the little mouths at the apex, resembling 
smoke coming out of a chimney pot. This is especially 
noticeable when the dry plants are squeezed or kicked with 
the foot. : 
LAKE ILLAWARRA. 
Along the shores of Lake Ulawarra in fresh and galt water 
marshes, quite a number of interesting plants were collected, 
including Sporobolus virginicus, Paspalum distichum, T'rign 
lochin striata, Cyperus polystachys, Scirpus nodosus, and 
Juncus maritimus. 
Three creeping plants with purple or pale bluish coloured 
flowers were very plentiful, there are Selliera radicans, a 
Goodeniaceous species, J/imulus repens, one of the Scrophul- 
arineae and Lobelia anceps, one of the Lobeliaceae, 
The leaves of Selliera radicuns were very badly infested 
with the aecidio spore stage of a fungus disease, Puceinia, 
probably P. Saccardoi Atriplex patula, Suaeda maritima, the 
common “Sea Blite,’’? as weil as Salicornia Australis and a 
Uhenopodium, sp., all members of the Chenopodiaceae or 
salt-bush family were in flower, and were specially interest- 
ing to some of the members, who had not previously seen 
these plants.

MOUNT KEMBLA. 
On Good Friday, the members were taken for a trip to 
Mount Kembla. 
The journey commenced from the boarding house near 
Lake Illawara, and as the two large drags were drawn by 
five and four horses, respectively, and as they were very fit, 
the journey through the undulating country, via Browns- 
ville and Kembla Grange, proved to be a very enjoyable one. 
Soon after passing Kembla Grange platform, a large patch 
of wild roge bushes, with pure white flowers, attracted our 
attention. These were examined the next day, and proved 
to be quite distinct from the common ‘‘Sweet Briar, Rosa 
rubigenosa, which was also found growing alongside, but in 
lesser numbers, and turned out to be Rosa turbinata, a
