possibly be the same species. When we consider that the involucres 
of these plants resemble corollas of the same size, it will be seen that 
they are highly ornamental before the flowers expand, and they re- 
tain their beauty in a great degree until the seeds are ripe. Their 
fragrance is at least equal to the Hedaroma latifolia of Lindley, which 
is Genetyllis citriodora of Endlicher; they are most desirable plants 
to introduce into cultivation. Two fine species of Calythrix have 
been found; one of the largest yet seen of the genus bears rose- 
coloured flowers, which become white before they go off; and one 
with reddish purple flowers—a fine plant. To the true Myrtacee 
many plants have been added. A AHypocalymma grows on Con- 
gineerup, in the woods at the east end of the mountain, a faithful 
drawing of which, leaves, flowers, and branches, might very well pass 
for the broad-leaved Italian myrtle. There is also a beautiful purple 
species of the Cardiomyrtus-section of this genus, which I observed 
on all the Toolbranup hills. To J?tutacee, especially to the genus 
Boronia, I have added several beautiful plants. In the swamps behind 
Cheyne’s Beach I observed a pinnate-leaved, black-flowered Boronia— 
a remarkable plant; it grows four or five feet, with drooping branches ; 
the corollas are yellow inside, but the yellow is not seen unless the 
branches are turned up; the flowers appear quite black; the anthers 
are smaller, and, I think, fewer in number than is usual in Boronia, 
and concealed by the projecting umbrella-like stigma; the plant has 
but little of the diosmaceous scent of Boronia, and the flowers are very 
fragrant in the night-time. A pinnate-leaved Boronia, with yellow 
flowers inside and out, and all the usual characters of the genus, is seen 
on the side of the path from Cape Riche to King George Sound; a 
fine pinnate-leaved species with large rose-coloured flowers, grows on 
most of the Toolbranup hills; and one with trifid, very minute leaves ; 
together with a very smal] entire-leaved species, perhaps the B. tenwi- 
Jfolia of the Plante Preissiane, grows with it. The beautiful blue- 
flowered Hriostemon nodifiorum, found here, is a different species from 
our Swan River Z. nodifierum, which has white flowers, more or less 
tinged with rose colour, and a different habit ; it grows also in a very 
different situation, in the beds of stony brooks., The beautiful rose- 
coloured, sweet-scented Hibiscus of Cape Riche, is a very different 
plant from H. Hugelii ; and is quite distinct from H. Pinonianus, 
which grows with it, and bears purple flowers. I found a pretty white- 
flowering diceceous malvaceous plant, remarkable for having the male 
flowers much larger than the female ; the plant is very rare on the 
right bank of the Salt River, just by the second crossing-place from 
Cape Riche to the sandal-wood station. In regard to Epacridee, I 
have added many species of a new genus to this order ; I found two on 
Congineerup. The plants are of robust habit, and bear their flowers 
in the cone-like terminations of the branches; these all become white 
at the time of flowering, with the exception of the points of the leaves, 
in the axils of which the flowers are borne: these retain their green 
colour, From this colouring of the cones at the time of flowering, 
these plants are showy, as well as curious. I found a red-flowering 
Andersonia on Mongerup ; it is the only red flower I have seen of the
