384 HORTUS MORTOLENSIS 
first sown in several places by Mr. Daniel Hanbury, on December 
10th, 1874. 
CorTyLEDON. 
I maintain the genus in the sense of Pyrame De Candolle, for 
the African species. With the only exception of C. Eckloniana 
all the species enumerated succeed perfectly well. Some of the 
species, among them most likely C. macrantha, were introduced 
from seed sent by the late Prof. MacOwan, forty years ago. 
CRYPTOMERIA JAPONICA. 
For this fine Conifer our climate and soil are evidently little 
suitable. 
CRYPTOSTEGIA GRANDIFLORA. 
This beautiful climber was tried several times in the open, 
but without success. 
CUPRESSUS. 
IT am greatly indebted to Dr. A. Henry, of Cambridge, for the 
determination of the Cypresses of the garden. C. lusitanica is 
much grown, and varies a great deal individually in habit. All 
the trees of this species were raised from seeds received from 
M. Thuret, of Antibes, in February, 1869, as C. Benthami. Our 
largest trees are now about 16 m. high, with a crown of 12 m. 
diameter, and a stem of 2:20 m. circumference at the base, and 
1:70 m. at 1 m. above the ground. The type has rounded cone 
scales, the var. Benthamii has pointed ones. 
The tallest specimen of C. sempervirens was measured in 
1909 ; total height 31 m., bare stem 8 m., circumference 1:30 m. 
The tallest C. macrocarpa is 15°70 m. high, the stem is 3°45 m. 
in circumference. 
Cycas. 
C. Normanbyana and C. neo-caledonica were lost. Of 
C. revoluta only female individuals were known in gardens, but 
some years ago a good number of male plants flowered in Mr. 
Winter’s garden at Bordighera. We have now both sexes, and 
expect to have well-formed seeds in future. 
CYNOMORIUM COCCINEUM. 
This interesting parasite was grown for several years on the 
roots of Atriplex portulacoides. We are indebted for it to the 
Director of the Royal Botanic Garden at Cagliari. 
CYPHOMANDRA. 
C. betacea, the ‘tree tomato,’ has pleasant edible fruits. 
C. fragans, with showier flowers, was received from Kew, in 
October, 1903 ; so far this has not fruited. 
. DAHLIA. 
D. imperialis, the prince of the noble genus, presents a mar- 
vellous sight when in flower. It was introduced into the garden
