Stems in loose fascicles or solitary, ascending or suberect, usually 
from a decumbent and geniculate base, solid. Leaves firm, involute, 
especially towards the apex when fading or dry, with numerous 
thick rather prominent unequal contiguous sulv 
each of which is thickly clothed with minute asp* 1 
in 1 or 2 regular Imes, and glabrous or with 
soft distant hairs, green or glaucous. Spike ni. 
arching, lax, one-half to one-fourth of the wliole >- 
firm, glabrous, scabrous or smooth on the angles, i 
lets adpressed to the rachis or slightly curving 
flowered, but little longer than the intemodes, ari! i 
ling 2 intemodes, ultimately linear-elliptical, s-i . 
Glumes two-thirds to three-fourths the length of ^ 
half the length, subobtuse or subacute or apicul 
keel. Pales obtuse, apiculate or more rarely r 
rarely shortly awned. Axis of the spikelets pi: 
intemodes broad, greatly enlarged upwards. 
On sandy sea-shores. Probably common and ,<:< 
though I have not seen specimens fi-oni north ot

Intennediate in habit between T. pungens (particularly the con-

rigid, less upright, and almost always lerss geniculate towards the base- 
in the leaves being less rigid, from the ribs being not so prominent, 
and on this account they are also less regularly involute, and under
