THE AUSTRALIAN NATURALIST. 105. 
in Azalea, tlrere are only 5 stamens, the anther cells opening by 
a terminal pore, we can quite understand that the offspring as a 
result of crossing species of the above genera, would create a 
considerable amount of trouble for the taxonomist, who, perhaps 
was unaware that they were the products of crossing. Quite 
apart from these species or supposed varieties of species found 
in Nature or obtained as a result of artificial cross-pollination, 
there are other forms of plants to be considered, such as 
“chimaeras” and “sports,’ which by some are considered to be 
in the same category as “Graft Hybrids.” The bi-nominal 
system of nomenclature adopted in botanical works commences 
with Linne in his “Species Plantarum,” published in 1753, but 
as pointed out above, it has been found that many of the Lin- 
nean species contained elementary or micro-species. As many 
of the latter breed true, the term “Jordanon” species has also 
been applied. It will thus be seen that new names have had to 
be created when separating the latter. Several conferences have 
been held for the purpose of creating a regular system of 
nomenclature, which could be used and recognised by botanical 
workers in all countries. One of the most notable achievements 
made in this direction was the list of Nomina conservanda, 
which was passed by 133 votes against 36 at the International 
Botanical Congress of Vienna (1905). In the list referred. to 
there are quite a large number of generic names of: Australian 
plants, which have been preserved. To quote a few of our well 
known New South Wales genera, the following will give some 
idea of the changes which would otherwise have had .to. be 
made :— 
-Cynodon—This is our common “Couch Grass” (C0. dacty- — 
lon). American botanists adopt the: name Capriola of Adame 
son, published in 1763. The name Cynodon of Rich. ky be 
published until 1805. 
_Isopogon, R.Br., published in: 1809. . Abyliisy of Salisbury, 
published in 1807, is the same plant. 
Kennédya, of Ventenat, me is the same as Cautinia,» of 
Moench., 1802. 
reget R.Br., 1810, is the same as Tetons: of Salis- 
bury; 1809. 
Persoonia, Smith, 1798, is == Linkia, of Cavanilles, 1797... 
. Pimelia, of Banks and Solander, 1788, is: Banksia, of 
Forster, published in 1776, but not the Banksia, of Zann. f., Bubs 
lished:in. 4781.
