maritime fen pasture, on upland moors, on grass 

 moor, and amongst Arctic-Alpine vegetation. 



In habit the Arrow Grass is grass-like and of the 

 rosette type. The stem is swollen below. The 

 rootstock is tufted, and there are a few, slender, 

 creeping runners. The leaves are radical, slender, 

 limp, faintly grooved above, succulent, swollen and 

 sheathing below, half round in section. 



The flowers are borne on a slender scape, in a long 

 raceme, which lengthens in fruit, on short ultimate 

 flower-stalks. The flowers are small, yellowish- 

 green, stalkless at first. The perianth-segments are 

 broadly ovate, and purple at the border. There are 

 six stamens in two rows of three each. The anthers 

 are purple. The stigmas are feathery and project 

 beyond the nearly equal perianth-segments. The 

 perianth-segments fall, and the fruit, which is 

 appressed to the scape, and club-shaped or hastate, 

 lengthens, tapering below. When ripe it separates 

 from below upwards into three carpels with a central 

 axis. The carpels are round at the back, narrow 

 below, with the axis three-sided. There may be three 

 abortive carpels between the three fertile ones. 



In height Arrow Grass varies from 6 to 12 in., but 

 I have found it to be nearly 18 in. occasionally. It 

 flowers from May to September, and is a herbaceous 

 perennial. 



The flowers are inconspicuous. The stigma ripens 

 two to three days in advance of the anthers. By 

 secondary growth the inner whorl of perianth-
