SOME INTERESTING PLANTS FROM THE NEPEAN 
RIVER. 
Prostanthera incana, Cunn.—This is a very handsome 
shrub, and several attempts have been made to add it to our 
garden flora. The seeds germinate freely, but there is a 
deplorable mortality amongst the transplanted seediings. 
When grown in pots and allowed to remain in them the plants 
languish, and finally wither away. 
P. Violacea, R. Br.—This species is of more interest from 
a botanical than a horticultural point of view. 
Isotoma axillaris, Lindl.—A pretty little herbaceous 
plant, closely related to the well-known Lobelia of our 
gardens. It grows freely from either seeds or cuttings. 
Myoporum floribundum, Cunn.—In the Fl. Austr. this 
species is recorded only from the Nepean River, in N.S.W., 
and the Snowy in.Vic. It has since been found on the coastal 
rivers (Shoalhaven, etc.), between these localities. It is a 
showy plant with a powerful odour, pleasant or the reverse 
(as is the case with many of our odoriferous plants), accord- 
ing to the impression made on the olfractory nerves of those 
who come in contact with it. The writer has not tested its 
cultivable qualifications. 
Anthocercis albicans, Cunn.—An attractive shrub, the 
the young shoots of an ashy grey colour. Growing on the 
banks of sand and detritus in the bed of the river at Douglas 
Park. Previous to this collection it had not been recorded 
from the eastern slopes of the ‘‘Great Divide.” ; 
sl. scabrella, Benth.—Known only from the Nepean un- | 
til 1901, when it was collected at Wallangarra by Mr. J. L. 
Boorman, of the Sydney Botanie Gardens, and recorded in 
the Proc. Linn. Scy., 1902. ‘Notes from the Botanic — 
Gardens.’’ Maiden and Betche. 
A. Hades, F. v. M—The only locality given for this, 
species in the //. Austr. is, near Camden, collected by 
McArthur. In Moore’s “Handbook” the range is extended, 
but no other specific locality is given. 
Didymotheca thesioides, Hook.—The male plant only was 
seen of this interesting dioecious species, which had not been 
found previously in N.S. Wales. 
Tmesepteris tannensis, Benth.—Usually an epiphyte on 
the trunks of trees. On the ‘‘Nepean”’ it specially favors the 
Tree Ferns. 
Heleocharis cylindrostachys, Boeck. (Douglas Park).— 
Previous to this collection not recorded from this locality. It 
has occurred to the writer that our Rushes and Sedges are not 
as much in evidence for decorative purposes as they deserve 
to be. Some effective “Studies in Black and Brown’’ may be 
obtained from combinations of our Restiaceae, Juncaceae, and 
Cyperaceae.
