C. indica in the features listed in Table 1, with the ex- 
ception of vessel member width. All three samples have 
gelatinous fibres. Crystals are absent in wood rays in 
two: only a few were found in the rays of the third 
sample. Complete data on these samples will be pre- 
sented in the future as part of an expanded study on the 
wood anatomy of Cannabis.
