76 Tamariscinecz Tamarix. 



1. T. Gdllica. 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. pentdndra, etc. 



2. T. tetrdndra, syn. Africdna, 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. T. Germdnica, syn. Myricdria. 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. 



ORDER XX.-HYPERICINE^E. 



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 baccate. Seeds few or many, 

 exalbuminous. A small order ; as characterised above, it does 

 not include all the exotic genera. 



1, HYP^RICUM. 



Characters as above. About 160 species, found in all tem- 

 perate regions, and at great elevations 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.
