Cannabis saliva, Linne. 



The Hemp-plant ; indigenous to various parts of Asia, as far 

 west as Turkey and as far east as J apan. Cultivated for its 

 fibre since ancient times. Particularly in hot climes it 

 exudes the " Churras," a resinous substance of narcotic 

 intoxicating property. The foliage contains also a volatile 

 oil, while the seeds yield by pressure the well-known 

 fixed Hemp-oil. The staminrferous plant is pulled for 

 obtaining the fibre in its best state immediately after 

 flowering ; the seeding plant is gathered for fibre at a later 

 stage of growth. Good soil, well-drained, never absolutely 

 dry, is needed for successful Hemp culture. Hemp is one of 

 the plants yielding a full and quick return within the season. 

 The summer temperatures of St. Petersburg (67° P.) and of 

 Moscow (62° P.) admit yet of the cultivation of this plant. 

 The Hemp as a narcotic plant serves as a protection against 

 insects on cultural fields, if sown along their boundaries. 



Capparis sepiaria, Linne. 



From India to the Philippine Islands, ascending to cool 

 elevations and living in arid soil. A prickly bush, excellent 

 for hedges. Dr. Cleghorn mentions also as hedge-plants 

 C. horrida (L. fil.), C. aphylla (Roth), C. Roxburghii (Cand.), 

 some of which yield also capers. 



Capparis spinosa, Linne. 



South Europe and North Africa, South Asia and North 

 Australia. A somewhat shrubby and trailing plant, deserving 

 even for the sake of its handsome flowers, a place in any 

 garden. It sustains its life in the most arid deserts. The 

 frosts of our lowlands do not destroy this plant. The flower- 

 buds and young berries preserved in vinegar with some salt 

 form the Capers of commerce. Samples of Capers, prepared 

 from plants of the Botanic Garden, are placed in our Indus- 

 trial Museum, together ^vith many other industrial products 

 emanating from the writer's laboratory. The Caper-plant is 

 propagated either from seeds or suckers ; it is well able to 

 withstand either heat or drought. The buds after their fii'st 

 immersion into slightly salted vinegar are strained and after- 

 wards preserved in bottles with fresh vinegar. Chemical 

 principle: Glycosid. 



Capsicum annuum, Linne. 



Central America. An annual herb, which yields the Chillies 

 and thus also the material for Cayenne Pepper. Chemical 

 principle : Capsicin, an acrid soft-resinous substance. 



Capsicum baccatum, Linne. 



The Cherry-Capsicum. A perennial plant. Prom Brazil
