BOTANY OF VICTORIA. 241 
received from Dr. Behr, its discoverer; the flowers of it are, as you 
will observe in the specimens forwarded last year, white, and during 
five years’ observation of this plant I never saw them yellow, nor the 
bracts tinged yellow as those of Euphorbias. Moreover P. dichotoma 
is a real scrub and desert plant, whilst P. flava is entirely absent 
from South Australia, and only makes its appearance in the more 
southern latitudes of this Colony, where Tasmanian plants predominate. 
P. nutans and P. cernua are varieties of P. linifolia. Grevillea Dal- 
lachiana will, I trust, retain its name, for neither the appellation alpina 
of Lindley nor alpestris of Meisner can be admitted, as the beautiful 
shrub grows in the warmest parts of the ranges, and even frequently 
in the scrub of fot plains. If ever ascending to subalpine altitudes 
(and I am not aware of it), it will be, like hundreds of other plants, in a 
crippled state. 
From Professor Lindley’s remarks on my Orchidacee there appears 
to be still a good deal to be cleared up. It is my intention to describe 
accurately all the species. It appears to me so improbable that plants 
like Caladenia mollis, which have such extensive range over the country, 
should have escaped R. Brown. The Microtis so common through 
South Australia, Victoria, and Van Diemen’s Land has been repeatedly 
examined by myself in a living state; it is unquestionably M. media, 
R. Br. M. rara and M. parviflora do not differ much from it. But 
I cannot adopt Lindley’s opinion it should be M. pulchella. I examined 
Microtis minutiflora in a living state; and after having seen this plant - 
now range as far as Gipps Land, I am inclined to take this for R. Brown’s 
puichella, notwithstanding it does not entirely accord with his diagnosis. 
With regard to my intended Flora of Victoria, I think it best that 
I should publish it here myself, I dare say in the Government printing 
office, i.e. in English. Before however I can make the beginning to 
this work several districts have yet to be visited, one of which will 
probably produce many Tasmanian forms; others have yet to be exa- — 
mined in a different season. E 
By my next journey I think to complete the botanical survey of this j 
Colony, and by the commencement of next year I hope to have, tomy | 
delight and instruction, the first fascicles of Dr. J. D. Hooker's Tas- 
manian Flora. I would venture then to follow with my own work, and | 
I do not see material difficulty in bringing it out here.
