Siberia to Japan, 1844. A rare and handsome species, not unlike 
T. sibirica. SYN. I. brachycuspis (under which name it is figured

Stem 6in. to 12in. high, slender. North America, 1826. (B. M. 3343; 
B. R. 1218.) According to Douglas, the Indians make from the 
fibre derived from the leaves of this species “deer and elk snares 
sufficiently strong to take even the largest and most powerful of 
these animals ; and it is also used by the women for making small 
bags and reticules, exactly the same as steel chain purses of fine 
workmanship, and for fishing.” i
