BRACHYPO'DIUM* *. 
Linnean Class and Order. Tria'ndria f, Digy'nia.

tucinve; type, Avenace.® ; Burn. Outl. of Bot. v. i. pp. 359 
and 369. 
Gen. Char. Inflorescence somewhat racemose. Spikelels (fig. 1.) 
alternate, remote, cylindrical-compressed, many-flowered, with a 
short pedicel, their sides directed to the rachis. Calyx (fig. 2.) of 
2, unequal, spear-shaped, sharp-pointed, concave, keeled glumes , 
containing many, alternate, 2-ranked, perfect florets. Corolla 
(fig. 3.) of 2 unequal paleee, the outer one generally awned at the 
extremity ; the inner one retuse. Scales ( nectary ) spear-shaped, 
hairy above, occasionally bifid. Filaments (see fig. 3.) 3, hair-like, 
shorter than the corolla. Anthers strap-shaped, pendulous, notched 
at each end. Germen (see fig. 4.) turbinate. Styles (see fig. 4.) 
short. Stigmas feathery. Ovary villous at the end. Seed oblong, 
quite loose, though closely enveloped in the unchanged corolla. 
The spike-like inflorescence ; the cylindrical-compressed, many- 
flowered spikelets , with their sides directed to the rachis ; the calyx 
of 2, spear-shaped, unequal glumes ; and the corolla of 2 spear- 
shaped palece, the outer one awned at the extremity, the inner 
retuse ; will distinguish this from other genera in the same class and 
order. It differs from Festuca (t. 324), in the spike-like inflorescence , 
and the retuse inner palea of the corolla. 
Two species British. 
BRACHYPO'DIUM PINNATUM. Winged Shortfoot. Pinnated 
False Brome grass. Spiked Heath Fescue grass. 
Spec. Char. Spike upright. Spikelets nearly cylindrical, 2- 
ranked, hairy. Awns shorter than the florets.
