curious. I found a red-flowering Andersonia on Mongerup; it is the 
only red flower I have seen of the genus. I have added many compo- 
site plants to my collection. Soon after the rains set in, a beautiful 
little annual everlasting flower covers the tops of the Perongarup hills, 
in many places giving them the appearance of being covered with snow. 
This little plant would be worth cultivating in England, and it would 
flower long before any of the other sorts from seed. I found a very 
curious plant of this order, of a genus different from any other I have 
before seen in this country, and bearing, in leaves and flowers, a con- 
siderable resemblance to the European Dandelion; it has a single, 
milky, tuberous root, the size and shape of a skirret; one is annually . 
formed, which flowers the following year, and, like some of the Or- 
chidee, the tuber which flowered the year before, is seen, in an exhausted 
state, by its side. I have made some additions to my collection of 
Proteacee. A large and showy species of Isopogon grows on the tops 
of all the Toolbranup hills; I suppose it is altogether a larger plant 
than the Z. latifolius of Mr. Brown. A remarkable Zsopogon—a stem- 
less species, with downy leaves, a foot long, divided as in Franklandia 
J'ucifolia—grows about the lakes to the east of Toolbranup; and a 
fine upright-growing thorny Adenanthos on the top of low ironstone 
hills in the same vicinity. In botanical characters, it comes near the 
A. pungens of the Plante Preissiane ; but that is a prostrate plant, 
covering the ground like a carpet, while this has no branches near 
the ground. A very curious Grevillea, with smooth, rigid, simply 
pinnate leaves, is seen in several places by the road-side in going from 
Cape Riche to the sandal-wood stations. I must leave some account of 
the Endogens I have met with to a future opportunity. 
In this journey I have made some observations on the influence the 
earth—I mean the particular sort of soil—has on the plants which 
clothe its surface. It is well known that plants vary according to 
latitude, longitude, and altitude; but the difference caused by all these 
in the extent of a few hundred miles, is not one-tenth part so great as 
that caused by the different nature of the soil, sometimes within the 
distance of one mile of the earth’s surface. I shall give a few striking 
examples:—The Perongarup hills lie at the distance of twenty-five 
miles to the N.E. of K.G. Sound, the Toolbranup hills, about twenty 
miles farther in the same direction ; they are clusters of hills or groups, 
both surrounded by what is called in this colony ironstone gravel—a
