THE GENTIAN GROUP. 
In the Order Gentianacez are included some of 
our most cherished wild flowers. The discovery, for 
instance, of a Wild Gentian marks a red letter day 
in the annals of the botanist. 
Gentians are arranged in two groups, the first with 
leaves opposite, and the corolla convolute or imbri- 
cate, including Exacum, having an ovary with two 
loculi, Erythreea, Chlora, in which the ovary has one 
loculus and a projecting placenta, Gentiana and 
Swertia, the same, with the placenta not projecting, 
and Menyanthes and Limnanthemum in which the 
leaves are alternate, the corolla induplicate, valvate. 
There are about a hundred and fifty species, which 
are found in every part of the world, often at great 
altitudes, as at 16,000 ft.in the Himalayas. They are 
abundant in the Alps. 
The European forms of the Gentian are blue, those 
of New Zealand red, as also in South America. 
They have bitter properties, and the roots are used 
medicinally, being employed as tonics. 
The Bog Bean is used in some districts for 
rheumatism. 
The order includes not only arctic and alpine plants,
