93. SPIRAA lanceolata. Poir. dict. 7. 353. Cambess. in ann. sc. nat. 1. 
366. t. 25. 
A hardy shrub with white flowers, native of China. It 
has the habit of Spirza bella, and others of the same section 
of the genus Spiraea, from which it is known by its lanceolate, 
lobed, and serrated leaves, which are quite smooth, but paler 
on the under than the upper side. ‘The clusters of flowers 
are on longer stalks than are represented in the figure pub- 
lished by M. Cambessédes, but it exactly agrees with his de- 
scription. In the gardens it is known under the name of 
Sp. Reevesiana. 
94. HIBBERTIA perfoliata. Hugel’s Enum. p. 3. 
A very handsome Swan River greenhouse shrub, with firm 
glaucous oblong leaves, stem clasping, terminated by a free point 
and slightly toothed at the margin. The flowers are single, op- 
posite the leaves, bright clear yellow, and almost as large as 
those of the old Hibbertia volubilis ; they are free from all 
unpleasant smell. The specimen before me is a foot high, 
branched from the base, as it is described by Endlicher in 
Hugel’s enumeration. But I find no sign of twining, and the 
stems are very slightly four-cornered, while the ovaries vary 
in number from four to five, the number three not having 
been found upon any one of the four flowers that expanded ; 
nevertheless I entertain little doubt that these differences 
arise from the state of Baron Hugel’s dried specimens. Occa- 
sionally the leaves are slightly repand. This species has 
_ flowered in the garden of the Horticultural Society.

es, with two or three whorls of narrow 
glaucous leaves, and pyramids of bright pink flowers placed 
tier upon tier. It is a greenhouse plant, and probably an 
annual, native of the Swan River colony. It has flowered in 
several collections near town.
