Dicotyledons with Incomplete Flowers — Cannabinacece* 
97 
Stem erect and leaves digitate in Hemp (Cannabis); twining, and leaves simple, in Hop ( Humulus ). 
Bracts of the spicate pistillate flowers of Hop accrescent, loosely imbricating, forming a globose or ovoid 
head. 
Perianth of staminate flowers regular, 5-phyllous ; of pistillate flowers, reduced to a single enveloping scale. 
EMBRYO of Hemp once-folded, of Hop spirally coiled. 
USES, &c.—The bark of Hemp (Cannabis sativa) affords on maceration a fibre of great tenacity, which has 
been in use from remote antiquity in temperate countries for the fabrication of cordage and of strong coarse cloth. 
The same plant cultivated in a warmer climate develops a dangerously narcotic resin in the glands of the herbage, 
which is collected in India and Arabia as an intoxicant. The Hop, used in brewing, owes its value to a bitter 
aromatic narcotic gum-resin developed in the microscopic glands scattered over the surface of the enlarged bracts 
and nuts of the fruiting spikes. 
Natteral Order 
MORACEiE. Tab. 81.

ovules variously inserted. 
Distribution. —Chiefly Tropical and Subtropical, although two or three of the species most 
important to mankind belong to the North Temperate zone, as the Fig (Ficus Carica), now cultivated
