CARDEN PLANTS — THEIR GEOGRAPHY, XX. 
ROSALES, (C. ) 
THE GENISTA, ROSA AND DROSERA ALLIANCE. 
Continued. 
Sempervivum “houseleeks” have about 50 spe- 
cies from Europe, Northern and Eastern Asia, North 
Africa and southwards in the mountains. None 
are Californian. Several have been and are 
used for edging and working out designs in 
flower beds, and for such purposes and for rock 
works they are well adapted. In company with 
species of the last genus pleasing masses of color 
may be worked out. 
Drosera “sundews” in 100 species usually in- 
habit very different stations. They are scattered 
over the bogs and moist pastures of the world, only 
occasionally attaining to anything above the most 
humble proportions. They are reported carnivorous. 
Drosophyllum Lusitanicum extends from South 
Western Europe to the Mauritius. It grows in sandy 
places to a foot or more high, has yellow flowers, 
and is a fly catcher. 
Dionosa is the curious and somewhat anomalous 
“Venus fly-trap” found chiefly on the coast lands 
of North Carolina and more sparingly southwards. I 
had a good quantity of seed of this plant collected 
for Kew years ago, to be used in raising plants for 
the investigations of the late Chas. Darwin. The 
feeding to them of unnamed quantities of beefsteak 
did not appear to render them more robust, and it is a 
question whether their leaf-trap isof real use to them. 
Roridula is a genus of South African fly-traps 
HAM AM ELIS ARBOEEA. LOROPETALUM CH1NENSIS. 
in 2 species. They attain to the dignity of shrubby 
plants of from 3 to 6 feet high, and the branches 
are used to catch flies by the colonists. 
Parottia belongs to another and dissimilar tribe. 
There are 2 species from Persia and Cashmere. 
The Persian is hardy and colors finely in autumn. 
Fotlicrgilla is a monotypic native shrub. 
Corylopsis has 4 species from Japan, China and 
the Himalayas. One or two are in gardens. 
Hamamelis “witch hazels” are in 3 species, and 
are Asiatic and North American. The native kind 
flowers in the late autumn southwards or early winter 
northwards. The Asiatics and their varieties are 
more disposed to flower in winter or early spring ac- 
cording to the climate in which they grow. They 
are interesting shrubs but seldom seen in gardens. 
Loropetalum Chinensis is the only one of the 
genus and in close affinity. 
The curious Rhodoleias, Disanthus, Bucklandias 
and Altingias are all found in Indian or Eastern 
Asiatic countries, and it is largely due to them, or 
some of them, that the following genus found its 
way to this alliance, all the way from the neighbor- 
hood of the plane trees. 
Liquidamber is now credited with 2 species, 
the well known handsome “sweet gum”’ and the 
species from Asia minor. It is remarkable that as 
fine a tree as the sweet gum is not used as a street 
tree in preference to the soft maples and poplars. It 
is far more bonnie. 
The tribe Brunitxz contains a number of hand- 
some evergreen shrubs and small trees from South 
Africa in the genus Berzelia, Brunia, Berardia, 
Stavia and Linconia, only useful outdoors in such 
favored climates as California. 
The Haloragece are mostly aquatic or marsh 
herbs, differing widely in aspect however, until it 
seems as though the tribe were a refugium for the 
botanists — yet no doubt they resemble each other in 
permanent characters of flowers and fruit, and it is 
to be hoped they will cease to be shifted about
