of the midrib, truncated or somewhat heartshaped at the base, coria- 
ceous and very much reticulated on both sides. RacEmes axillary 
or terminal, varying much in length, but always considerably longer 
than the petioles, and many flowered. Prprcets one flowered, gener- 
ally two together from the same point, with minute bractez at the base, 
Bracreou# wanting. Catyx bell-shaped, pale green, with five short 
teeth, of which the two upper are joined together into a sort of upper 
lip. Perrats in the ordinary variety of a deep blue, in that now fig- 
ured of a reddish lilac. Sranparp patent or bent back, nearly orbi- 
cular, emarginate at the top, and contracted at the base into a short 
stalk, marked in the centre with a double green spot. Wines and 
keel borne on longer stalks and darker coloured than the standard. 
Leeume linear, compressed, smooth, generally about an inch long, 
Popuar anD GeoerapnicaL Notice. Hardenbergia, a group 
separated from the old genus Kennedya, contains six species of climb- 
. ers, all found in extra-tropical Australia, all of them very much alike 
in general appearance and colour of the flowers, and all highly orna- 
mental from the great profusion of their flowers when under proper 
treatment, and next to the Zichyas, they form the handsomest of the 
groups of which the old genus Kennedya consisted, and which are still 
known under that name in our gardens. 
As this dividing of Kennedya may probably be the occasion of 
a repetition of the complaint against botanists, that they are con- 
tinually changing the names of plants, it may not be out of place to 
add here a few remarks on the principles which have guided those who 
have made really useful changes ; and by which, however much they 
may have been lost sight of by many an aspirant to botanic fame or 
notoriety, the validity-of any proposed alterati h 
ll 
ever be tested. 
The name under which a plant was first published, commencing 
from the time of Linneus, should not be altered except in the follow- 
ing cases : = 
1. Unless it be preoccupied by another plant. : 
2. Unless it be the name of a genus to which the plant does not in 
fact belong. 
3. Unless the progress of science render it expedient to divide the’ 
genus. . 
4. It has also been contended by some, 
that where the name of a 
plant has been preoccupied by Zoologists 
it ought to be changed;
