Description

(From Hooker[1]

At our Tab. DCCXXVIII (should read DCCXXXI), is figured a small annual species of Triglochin with winged fruit, and that fruit, at the base, produced into six short spines. In the present instance, besides a different shape of fruit (the cells being destitute of wings and rounded at the back), the base is prolonged into six very long horizontal spines, placed in pairs, giving the fruit a miniature resemblance to that instrument of war, the Caltrops, whence is derived the specific name.

HAB. Swan River, Western Australia. Mr. James Drummond. n. 17, 1845
