erect, and in having its leaves opposite at the base and scattered 

 above. The $ -inflorescence is not cone-like as in the Hop, but the 



flowers are similar in construction. The main 

 difference is to be found in the axillary shoot, which was

 in medicine and are officinal. The bast of the stems 

 of the Hemp is also used and the fat oil of the seeds. In Oriental countries 

 the entire plant is used in the preparation of an intoxicating drink (haschisch), 

 the narcotic material being found in the glandular hairs.

Family 6. Polygoniflorae. 



This family is on one side closely allied to the Urticacece by its

 which envelopes the younger leaves in the bud, similar charac-
