CLASS HI. ORDER II.] DIGITARIA. It 



sessile, on an angular, somewhat rough, striated, zigzag rachis, glossy 

 mostly purplish. Glumes narrow, acute, keeled, rough towards the 

 point, spreading, which makes the spikes appear rough and spiny. 

 Glumelles unequal, smooth, compressed, keeled; the outer valve much 

 the broadest, slightly hairy on the keel and inner border, enwrapping 

 the smaller inner valve. Glumellules Iwo small scales. Styles distinct, 

 long. Stigmas feathery. Fruit small, ovate, enclosed in the hardened 

 glumelles. 



Habitat. Very rare ; on the sandy shore between Penzance and 

 Marazion, Cornwall. 



Perennial; flowering in July and August. 



The long, branched, and rooting underground stems of this plant are 

 admirably suited to the loose sandy situation of their growth. 



This species, according to A. B. Lambert, Esq. in the 6th vol. of the 

 " Transactions of the Linnean Society," is' identical with the famous 

 doobgrass of the Hindoos, who worship it in the most extravagant 

 manner, as the " Divinity not subject to age or death the armour of 

 India, the preserver of regions, the destroyer of enemies, a gem that 

 gives increase to the fields," &c. (See the Works of Sir Wm. Jones, 

 vol. ii.)
