A STUDY OF SYSTEMATIC WOOD 
ANATOMY IN CANNABIS 
BY 
Loran C. ANDERSON! 
Cannabis has been associated with man since very early 
times (Ash, 1948), yet, surprisingly, little is known about 
its comparative wood anatomy. The reasons are due 
probably to the tendencies for (1) anatomists to select 
wood from trees and woody shrubs rather than from 
herbs for study and for (2) researchers often to disregard 
or slight plants associated with man, either as crops or 
weeds, in basic scientific enquiries. 
Tippo (1988) offered a few general comments on the 
wood of C. sativa L. in his extensive study on the anato- 
my of the Moraceae and its allies. Stem shape and leaf- 
trace number in transections were stressed by Nassonov 
(1940) in a report on geographical races of hemp. Hay- 
ward (1948) devoted a chapter in his textbook to C. 
sattva. The general morphology of that species was 
given, but details of seedling anatomy and floral struc- 
ture were emphasized; wood anatomy was scarcely men- 
tioned. Metcalfe and Chalk (1950) summarized anatomi- 
‘al data on Cannabaceae to that date. Shimomura e¢ al. 
(1967) emphasized trichomes in their study of leaf and 
bract anatomy in Cannabis; they found differences be- 
tween C. sativa and C. indica.
