 margins when more accurate 

 terms, such as serrate or cre-

 when stamens are so long that 

 the anthers are held out be- 

 yond the corolla tube. 



Exfoliate. To peel off in layers.

 on which such flowers are 

 borne. 



Filament. The stalk of a sta-

Glabrous. Devoid of hairs. 

 This is the opposite of pu- 

 bescent. 



Gland. A small plant organ 

 which has the function of 

 secretion. Glands may occur 

 on petioles as small warts, 

 on the tips of teeth as minute

 leaf tissue as minute clear
