CANNABIS (the ancient Greek name). Urticacece. 

 HEMP. A single species, probably native to central Asia, 

 and now widely cult, as a fiber plant. Hemp is also grown 

 occasionally as an ornamental plant, being grown from 

 seeds and treated as a half-hardy annual. It makes ex- 

 cellent screens in remote places. It thrives best in a rich, 

 rather moist soil. C. sativa, Linn., is the only species, 

 but various forms have received specific names. In gar- 

 dens, the form known as C. gigantea is commonest; this 

 reaches a height of 10 ft. and more. The seeds are usu- 

 ally sown where the plants are to stand ; but if quick 

 effects are wanted, they may be started indoors in pots or 

 boxes. Hemp is dioecious. The staniinate fls. are in 

 axillary panicles, and have 5 sepals and 5 drooping sta- 

 mens. The pistillate fls. are in short spikes, with 1 sepal 

 folding about the ovary. Lvs. digitate, with 5-7 nearly 

 linear, coarse-toothed leaflets. The plant is annual, 

 roughish and strong-smelling. j^ H. B.
