378 HORTUS MORTOLENSIS 
ribbed branchlets; the rather large cones are ovoid with acute 
valves. C. glauca is a smaller tree with somewhat thick and 
roundish 10-12 ribbed branchlets. 
A plant received in 1902 as C. sumatrana from Messrs. Veitch 
& Sons I presume to be the widely distributed and more tropical 
C. equisetifolia. Similar in habit is another tree, which may be 
C. torulosa. Neither has yet fruited. 
Casuarinas produce an excellent, very hard wood.* 
CATHA EDULIS. 
An evergreen shrub, first planted by Sir Thomas Hanbury, 
November 27th, 1868, who had procured it from Messrs. Veitch 
& Sons. In Southern Arabia the plant is known as “ Kat,” of 
which the Latin name is an adaptation. The Arabs chew the 
leaves for a tonic, and also make something like a tea from 
them. t 
CEDRUS. 
Of this genus C. Deodara is doing best. C. atlantica and 
especially C, Libani are apt to die without visible cause, probably 
on account of our long summer drought. 
CERATONIA SILIQUA. 
The “St. John’s bread tree,” ‘‘ Locust-bean tree,’”’ or ‘“‘ Carob 
tree.” Twelve young trees were planted in December, 1867; they 
are now fine large trees, mostly male, the tallest measuring 8:00 
m. with a stem of 2°50 m. in circumference. 
CERBERA LACTARIA. 
This beautiful plant has been tried, like Plwmiera alba and 
P. rubra, but cannot be grown in the open. 
CERCIS SILIQUASTRUM. 
Known as the “Judas tree,’ is extremely beautiful when 
in flower. It is a native of this coast. Our specimen is 8:00 
m. high, with a stem of 2:00 m. in circumference at the base. 
CEREUS. 
In June, 1868, Mr. Daniel Hanbury brought two large cuttings 
of C. perwvianus from Nice, and planted them against a wall. 
Strangely enough, however, C. peruwvianus does not succeed in 
most parts of the garden, though it grows well in the neighbour- 
hood, otherwise these first two cuttings ought to have grown by 
now into big trees. He also planted, in July of the same year, 
C. nycticalus, C. tortuosus, and C. triangularis, which he had 
received from Kew, and C. hamatus, which was obtained from
