Of these 65 species 54 are hemicryptophytes (H), 7 cha- 
maephytes (Ch), 2 geophytes (G), and 2 therophytes (Th). The 
percentages are given in table 4. Compared with the plants 
of "the Pamirs” those of the northern slopes show a greater 
preponderance of hemicryptophytes and much fewer chamae- 
phytes (11 °/o compared with 29 °/o).
