76 Tamariscinee—Tamarix. 
1. T. Gallica.—This is the common species, growing from 
5 to 10 feet, with long and slender branches, and almost 
feathery ultimate branchlets. Leaves very minute and trian- 
gular, larger on the older branches and subulate. Flower- 
spikes lateral ; flowers pentamerous, rose, pink or white ; bracts 
acuminate-cuspidate. This is naturalised in some parts of 
Britain. It includes T. Anglica, T. pentandra, ete. 
2. T. tetrandra, syn. Africana, parviflora, etc., of gardens. 
——The flowers in this species are usually tetramerous, and pro- 
duced from the old wood. They are white, tinged with red. 
The varieties referred here are not so hardy as the foregoing. 
The true plant is from south-eastern Europe, but the species 
are very difficult of determination, and possibly this may be 
incorrectly named. 
3. LT. Gerimanica, syn. Myricarica.—Distinguished from the 
true Tamarisks by 5 sepals, 8 petals, and 10 stamens combined 
at the base. A shrubby plant 4 to 8 feet high, with very 
small leaves and red flowers in terminate bracteolate spikes 
from 2 to 3 inches long. A native of Central and 
Southern Europe, blooming all the Summer. 
Orprr XX.-HYPERICINEZ. 
Herbs or shrubs with opposite simple exstipulate entire or 
glandular-toothed leaves, often having transparent glands, and 
yellow (rarely white) flowers. Sepals 5 or 4, imbricate. Petals 
of the same number, contorted in the bud. Stamens usually 
numerous, and united in three or more bundles, rarely few with 
free filaments. Fruit capsular, composed of 3 to 5 united 
carpels dehiscing septicidally, or baceate. Seeds few or many, 
exalbuminous. A small order; as characterised above, it does 
not include all the exotic genera. 
1. HYPERICUM. 
Characters as above. About 160 species, found in all tem- 
perate regions, and at great clevations within the tropics. The 
name is of Greek origin, supposed to have been applied to a 
species of this genus. Popularly known as St. John’s Wort. 
There are 9 or 10 British species, 
1. H. calycinum. Rose of Sharon, Aaron’s Beard.—This 
species has larger flowers than any other, and is the one most
