species which agree with our plant in habit and in having 
narrow leaves are P. linearis, R. Br., and P. empetrifolia, 
Sieb., the latter figured in t. 3405 of this work under the 
name Chilodia scutellarioides ; both of these, however, have 
a distinctly two-lipped corolla, the upper lip being much 
the shorter, and are therefore very different from the 
species here figured. With the true P. phylicifolia, F. 
Muell., for which our plant is apparently mistaken in New 
Zealand, it has little in common, for P. phylicifolia is much 
more woody, its leaves are broader, shorter and conspicu- 
ously revolute, its corolla is altogether different, and its 
anthers are appendaged. The genus Prostanthera, which 
includes over fifty species, is restricted to Australia, the 
eastern ‘portion of the continent being the home of the 
majority. Many of these species were formerly cultivated 
in this country as greenhouse plants together with other 
showy Australian species. Now they are hardly known 
outside the limits of botanical collections. But the one 
here figured, now introduced by way of New Zealand, is 
not one of these, nor indeed is it one that has ever been 
previously described. In Baron von Mueller’s Second 
Census of Australian Plants, where forty-four species are 
enumerated, twenty-eight are recorded from New South 
Wales, eighteen from Victoria, thirteen each from Queens- 
land and South Australia, seven from Western Australia 
and three from Tasmania; several of the species are 
common to two or more of these states. We have so far 
failed to ascertain from which of these subordinate areas 
P. pulchella may have found its way to New Zealand, 
while it is almost as difficult to suggest where it should be 
placed within the genus to which it belongs. In the Flora 
Australiensis the species are disposed in two sections. In 
one of these, Euprostanthera, the corolla tube is short and 
wide, the upper lip is short, very broad and erect, the lower 
lip is much longer and spreading, while the lips of the 
calyx are usually closed over the fruit. In the other, 
Klanderia, the corolla tube is incurved and dilated upwards, 
the upper lip is erect and concave and is as long as or 
longer than the spreading lower lip, while in fruit the lips of 
the calyx usually remain open. <A third section, Depresme- 
nilia, has been added in the Natiirlichen Pflanzenfamilien ; 
the most salient feature of this is that the calyx is shortly
