LXXV. GNETACEJE \ .E'PHEDRA. 937 



Height 3ft. to 4ft. Introduced in 1714. Flowers, in sessile catkins, 

 brownish ; March and April. 



The young branches are downy. Leaves alternate, oblong, linear ; cut on 

 each side into rounded and numerous lobes, like those of the ceterach ; and 

 sprinkled with shining dots, like those of the gales. This shrub is very hardy, 

 but it requires peat earth and a shady situation. Propagated by layers, suck- 

 ers, or seeds. The first and second methods are the most common, as good 

 seeds can rarely be procured.

Derivation. From ephedra, the Greek name for the //ippuris, or Horsetail, which it resembles. 



Gen. Char. See Ord. Char. 



Low shrubs ; evergreen, from the colour of the bark of their branches, and 

 in that respect resembling the genera Casuarina and .Equisetuni. They are 

 natives of the South of Europe, Barbary, and Siberia, on the sea-shore, or in 

 saline or sandy wastes ; and they have been but little subjected to cultivation. 

 According to Du Hamel, they bear the shears well, and form beautiful round 

 balls, which may either be made to appear as if lying on the ground, or may 

 be supported on a short stem. The lower sorts, Du Hamel continues, may 

 be clipped to resemble turf; and for that purpose the plant may be valuable, 

 in some parts of Australia and Africa, to form lawns which shall create an 

 allusion to temperate climates. The saving by using such plants as .E'phedra, 

 which would require little or no watering, instead of a great deal, as the 

 European grasses do in such a climate, would be very considerable.
