RUTACEjE. 
Generic Character. — Calyx four- parted. Petals j divaricate, with a solitary, compressed, ovate seed in 
four, inserted in a hypogynous disk. Stamens four, 
alternating with the petals, exserted ; filaments awl- 
shaped, smooth, each furnished with a simple gland on 
the inside at the base ; anthers heart-shaped, oscilla- 
tory. Disk surrounding the ovaries, and connected with 
the calyx. Style four-furrowed, short, smooth, termi- 
nated by a four-lobed capitate stigma. Carpels four, 
connected into a four-lobed, four- celled capsule; lobes

Specific Character. — Plant shrubby, evergreen, 
growing about a foot high. Branches quite smooth. 
Leaves opposite, trifoliate ; leaflets linear-lanceolate, 
revolute, acute, smooth, longer than the petioles. 
Peduncles usually having three branches, sometimes 
but two. Corolla pinkish-white, or blush-coloured ; 
petals reflexed. 
Zieria Smithii, which has the synonyme of Z. lanceolate is almost the only 
species of the genus with which ordinary cultivators are familiar ; and is noticeable 
for the erectness of its habit, the denseness and stiffness of its branches, and the 
great number of its pretty white blossoms, which appear in February or March, 
and continue unfolding nearly all the summer. 
The species here figured differs very materially from that just referred to. It does 
not grow so tall, nor so vigorously ; the shoots are neither so abundant, so strong, 
nor so upright, and they, as well as the leaves, are destitute of the hairiness which 
is apparent in Z. Smithii. Moreover, the flowers are arranged more in clusters, 
stand out better from amongst the foliage, and are thus more conspicuous, while 
their colour is a pale pink or blush towards the border, and whitish in the centre. 
Z. laevigata^ therefore, is altogether a more graceful and elegant plant than Z. Smithii, 
although it wants its aspect of health and robustness. 
In a collection of choice greenhouse plants for which Messrs. Rollisson, of 
Tooting, had set apart the beds of a small span-roofed house, we met with this plant 
flowering beautifully in April and May, 1841. The structure being a narrow one, 
it has a walk along the middle, and between this and the side walls, a brick pit is 
raised to within about three feet of the roof. The upper portion of the pit is filled 
with soil, and in it are placed specimens of rare greenhouse species. Although the 
object, in the particular instance mentioned, is, by keeping a rather high temperature,
