SPORES AND GLANDS. 



The pharmacist employs three drugs that come under this 

 heading, viz., lycopodium, lupulin, and kamala. The struc- 

 ture of all of these is simple, and as the individual spores or 

 glands are of very small size, they are usually entire. Adultera- 

 tion, intentional or accidental, is very readily detected. 



(135) Lycopodium. 



Lycopodium consists of the spores of Lycopodium clavatum, 

 L., N.O. Lycopodiacese, and probably other species. 



Each spore has the shape of a low, broad, triangular pyramid 

 resting upon a convex base, and is covered by a delicate network 

 consisting of colourless, raised, transparent ridges. The walls 

 are composed of an outer membrane bearing these projections 

 and a thin uniform inner one. The spores contain fixed oil 

 which can be made to exude by crushing them, and can be 

 identified by appropriate reagents.
