376 HORTUS MORTOLENSIS 
crowns of leaves. It was received from Kew in November, 
1871. 
CALLISTEMON. 
These Australian shrubs do very well on the Riviera and 
resist a good deal of drought. They mostly flower in early 
summer. Some twenty plants of different species were procured 
from Messrs. Huber & Co., of Hyéres, in the autumn of 1867. 
C. lanceolatus, C. linearis, and C. rigidus were grown from seeds 
received from Villa Thuret, in February, 1869. 
CALLITRIS. 
Seeds of C. quadrivalvis were received from M. Thuret, 
Antibes, in February, 1869. There are now many small trees in 
the valley and in the garden. The wood is hard, fine-grained, 
and very beautiful when polished. It was highly prized by the 
Romans under the name of Citrus.* 
CALODENDRON CAPENSE. 
Seeds of this were sent from the Cape by the late Prof. 
MacOwan in November, 1870. From these a large tree was 
grown, which did not flower until July, 1903, but now blossoms 
annually. This tree loses its leaves in spring for a few weeks, 
whilst some younger individuals remain leafless for a longer 
period. At present the tree is about 10°50 m. high with a stem 
of 1:20 m. circumference at the base. 
CALTHA. 
C. polypetala was brought ten years ago from the Vatican 
Gardens by Miss Hanbury. It much resembles C. palustris but 
is far more vigorous. 
CANARINA CAMPANULA. 
An interesting climber with a large fleshy rootstock. It rests 
during summer and completely dies down, but begins to grow in 
the autumn and flowers from midwinter to spring. It is rather 
sensitive to frost. The fruits (produced here only after artificial 
impollination) are eaten on the Canaries, where they are known as 
‘ Bicarro.” 
CanTvA. 
C. buxifolia was given to Mr. Daniel Hanbury by M. Thuret, 
of Antibes, in October, 1871. It is a most beautiful shrub, when 
in flower, but rather unsightly when at rest during summer. C. 
bicolor and C. pyrifolia, two equally interesting and beautiful 
species, are now lost from the garden. They came from the 
Imperial Gardens at Schénbrunn. 
CapPaRis. 
C. spinosa, the common caper, is planted on walls all along 
* See Strasburger, Rambles on the Riviera.
