THE STAMENS OR ANDRGECIUM. 

 Parts. 



Fii.AMKNT : the lower stalk-like part; it supports the anther 

 Fig. 140). Stamens are 



(a) Exsertfd, if the filaments are so long tliat tlie 

 anthers protrude beyond the {terianth (Fig. 141). 



(b) Inrlmlfd, if the filaments are not long enough to 

 raise the anthers beyond the ]>crianth (Fig. 12G). 



(c) Srjtxilr, if the filaments are absent (Fig. 142). 

 Anther : the swollen up|»er part, consisting of one or more 



uoually two) sars or colls which contain tlio ixilitMi 

 Fig. 139). 

 One surface of the anther is usually more deei)ly 

 than the other; this is the /ace, the other being 

 me 'J- 1' k.
