the Riviera, but is never seen to fruit here. Its variety rwpestris, 
which is distinguished by herbaceous and deciduous (not woody 
and spinescent) stipules, fruits abundantly. 
CARALLUMA. 
C. crenulata was sent by Lt.-Col. Dr. D. Prain, when Director 
of the Calcutta Botanic Garden, from the Shan Plateau in 
Burma, in April, 1903. It flowered freely in August of the same 
year, but did not live long. C. ewropea and its varieties are doing 
very well. The type collected on the Island of Lampedusa was 
sent in 1908 by the late Dr. Levier, from Florence ; var. Simonis 
was gathered in Tunisia by Dr. A. Aaronsohn in April, 1909. 
C. Nebrownii is the giant of the cultivated species. It was sent 
by Mr. K. Dinter and flowered repeatedly. One specimen was 
figured in Bot. Mag. t. 8267. Other species have been received 
from Mr. N. E. Brown, of Kew; Mr. K. Dinter, of Okahandya ; 
Cay. C. Sprenger, of Naples; Mr. G. Capelle, of Springe, &c. 
CARICA. 
C. candamarcensis was in cultivation for a number of years, 
and produced fruits, but was killed by frost in January, 1901. 
The plants were 2-3 m. high. The other species are deciduous 
and more hardy. Seeds of U. quercifolia were received from Cav. 
C. Sprenger, Naples, in February, 1902. 
CASIMIROA EDULIS. 
Two plants were sent out from England by Mr. Daniel 
Hanbury, September 22nd, 1869. They have grown into fine 
trees, about 9 m. high, flower every year, and often produce a 
good crop of fruit in October. The fruit is delicious when eaten 
at once, but becomes very bitter after a few days. 
CASTANOSPERMUM AUSTRALE. 
This beautiful tree, which does quite well in a garden at 
Garavan (Chalet des Rosiers), does not succeed at La Mortola, 
though it has been tried in almost every place in the garden. 
It is an evergreen, quick growing tree with interesting and 
beautiful flowers.* The fruits are edible when roasted, as are 
chestnuts, hence the name. 
CASUARINA. 
These are excellent garden trees, much planted along the 
Riviera. The tallest species, which is more or less pyramidal in 
habit, is C. swherosa. It has slender 6-8 ribbed branchlets, and 
small, somewhat elongate or oblong cones. Our largest tree is 
about 17 m. high with a stem of 2°20 m. in circumference. 
C. Cunninghamiana comes very near it, but has even finer 
branchlets, and smaller, nearly globular cones. C. stricta, the 
“She oak” of the Australian colonists, has long pendulous 9-14
