NOTES 385 
in December, 1867, from Hyéres. D. Maximiliana has shrubby 
stems, and is less beautiful. It was figured in the Botanical 
Magazine from La Mortola specimens. 
DASYLIRION. 
A genus of very ornamental plants, all having prickly mar- 
gined leaves, with the exception of D. quadrangulatwm which has 
smooth quadrangular leaves. D.Hookeri is now called Calibanus 
Hookervi Trel. (see Supplement and note). 
Datura. f 
The shrubby species are great ornaments of our southern 
gardens, especially during summer. Of D. arborea we only have 
the double-flowered form. D. sanguinea occasionally ripens 
fruits. -D. chlorantha came from Kew a few years ago. 
DENDROBIUM. 
D. nobile and D. densiflorum are not hardy here, but must be 
placed under glass during winter. They were received some 
years ago from Mr. Frederick Hanbury. 
DIANTHUS ARBOREUS. 
Tn brought from Kew by Mr. D. Hanbury, November 27th, 
DICKSONIA ANTARCTICA. 
A great many of these have been tried, but, like other tree 
ferns, did not succeed for the want of a sufficiently cool and 
shady place. 
DIMoRPHOTHECA ECKLONIS. 
I am informed that this beautiful little shrub contains prussic 
acid, and is, therefore, poisonous. 
DIOON EDULE. 
A large male plant was bought from Prince Troubetzkoy’s 
garden in July, 1888. It stands in a very sunny position, in dry 
sandy soil, and does extremely well. 
DIPLOPAPPUS. 
A genus scarcely differing from Aster. D. filifolius flowers 
in autumn and winter. It was introduced, March, 1870. D. fru- 
ticwlosus, introduced in March, 1872, has somewhat broader 
leaves, and flowers in spring. Both succeed well on dry and 
sunny banks. 
DorRYALIS CAFFRA (OR ABERIA CAFFRA). 
The ‘ Kai-apple” of South Eastern Africa, is a very thorny 
bush or small tree, suitable for hedges. In September it produces 
quantities of small apple-like edible fruits, which can be made 
into preserve. It was grown from seeds introduced by Mr. D. 
Hanbury in March, 1872. The plants are dicecious.
