ASTER FAMILY 63 
its name are the pistillate or seed-bearing flowers, while the staminate 
or pollen-bearing ones grow in heads on other stems. The botanical 
name for the genus refers to the fact that the protruded brown anthers 
of the staminate heads sometimes resemble the antennae of insects. 
The heads are creamy white with rose-colored bracts enclosing them 
at the base, and bloom in spring and early summer. The plants are 
2-15 in. tall and grow on prairies and in meadows and aspen woodland 
at 3000-10000 ft. The leaves are gray from the white wooly hairs 
covering them, and grow in clusters at the base of the flowering stems. 
These clusters usually form dense mats, the leaves of which are some- 
times chewed by children as Indian Tobacco or Ladies’ Tobacco.

grow 1-3 ft. tall in meadows, fir forests, aspen woodlands and on 
gravel-slides at 5000-10000 ft. and bloom in midsummer. They are 
beautiful enough to be given a place in the garden.
