[or the violet, where it forms the orange tip to the sta-

which is Ms within the anther, the filament may be en- 
tirely wanting, as in Orchidez, Ver- 
bena (Fig. 271), [and Viola], when 
the anther is said to be sessze. In 
the grasses (Fig. 270), the anther is 
fixed transversely to the filament. 
Of great importance in connec- 
tion with classification are the mode 
of attachment and number of the 
stamens, as well as the relative
