 and forming a kind of bag, they are called glandular 

 hairs* 



Hairs grow upon other parts of plants besides 

 stems, and the surfaces upon which they grow are 

 described by various terms, according to the character 

 and quantity of the hairs which may be upon them. 

 Many of these terms are words in common use, 

 such as woolly, silky, etc. Some need a word of 

 explanation, such as pubescent^ or downy ; setose^ 

 or bristly ; toi)ientose,\ or felted. 



When a surface is smooth and free from hairs, it is 

 said to be " glabrous "$

 or vessel more or less nut-shaped, cf. Gland, in Appendix.

 bristle; and " tomentum" locks clipped off wool. Tomentose, short 

 dense, matted hairs, making a surface like felt on a woolly surface the 

 matted, curled hairs are longer.
