Has. Swan River, Western Australia. Mr. James Drummond, 
n. 5, 1845. : 
We have here a new and very pretty species of Triglochin, 
from Mr. Drummond’s last collection of Swan River plants. 
It is small, but quite distinct from any yet described. The 
small plants seem to grow in a tufted or ceespitose manner. 
Leaves } to 3 of an inch long, narrow-linear, approaching to 
setaceous, obtuse, the base singularly dilated, concave and 
sheathing. Scapes 2-3 inches high, slender, the upper half 
occupied by the spike of from 5-7 flowers. Our specimens are 
with immature fruits, so that the perianths are unknown to us; 
the scars whence the sepals have fallen, only, remaining upon @ 
thickened, fleshy, elongated receptacle, on which rests the 
elongated linear-pyramidal, 3-celled capsule, crowned with three 
globular, velvety stigmata. Each perfect cell (or carpel) 
alternates with an abortive one, and is trigonal, the dorsal 
surface plane, with a slightly elevated, central line or carina, 
and on each side a prominent edge or wing, which at the base 
is prolonged into a short but prominent spur : hence the base of 
the fruit presents six of these spurs.
