female ones in spikes. Stamens 5. Fruit 

 a broadly ovate flattish achene enclosed 

 in the perianth segment. 



CuUiire and Propagation. — The Hop 

 is a beautiful and vigorous climber, well 

 adapted for covering trellises, arbours &c. 

 during the summer months. It flourishes 

 in a rich deep loam, and prefers open 

 sunny situations to dark shady ones. 

 Increased by seeds sown in heat in spring 

 or by division of the rootstock. 



H. japonicus {Japanese Hop). — An 

 annual species, native of N. Japan, with 

 vigorous climbing stems heavily covered 

 with roughish hairs. The stems often 

 attain a length of 15-20 ft., and are 

 furnished with broadly oval or rounded 

 leaves, cut more or less deeply into 5-7 

 crenulate toothed lobes, somewhat larger 

 than those of the Common Hop and paler 

 in colour beneath. The male flowers are 

 in branched few-flowered panicles ; the 

 female ones are borne in the axils of 

 the deltoid pointed bracts, the imion 

 of which with the perianth segments 

 forms a roundish or ovoid spike. Fruits 

 (achenes) shining and yellowish. 



There is a beautiful variety of this 

 species having the green leaves blotched 

 and streaked with pale and deep yellow. 

 It is caHei japonicus foUis vaviegatis. 



Culture and Propagation. — This is 

 not quite so hardy as our native Hop, and 

 should be grown in warm sheltered spots. 

 It may be raised like other tender annuals, 

 by sowing seeds in March in heat and 

 growing the young plants on to be fit for 

 planting out at the end of May. In warm 

 locaUties the seed, when ripe, wiU sow 

 itself, remaining in the ground iminjured 

 during the whiter and producing vigorous 

 plants in spring. 



H. Lupulus (Common Hop). — A vigor- 

 ous climber, native of the north temperate 

 hemisphere, with rough angular branch- 

 ing stems and opposite stalked heart- 

 shaped serrate leaves, deeply veined and 

 roughish to the touch. Flowers-in sum- 

 mer, greenish-yellow ; male ones in loose 

 axillary panicles ; female ones shortly 

 stalked in roundish heads or spikes. 

 There are several varieties. 



Culture and Propagation. — The Com- 

 mon Hop is a very useful plant for clam- 

 bering over hedges, trellises, &c. It may 

 be increased by seed sown when ripe in 

 warm sheltered spots in the open air or 



in cold frames ; or by division of the root- 

 stocks in early autumn when the leaves 

 are browning, or in spring. The flower 

 spikes of this species are used for brewing, 

 and acres of the plant are cultivated in 

 the south-eastern counties of England. 



CANNABIS (Hemp).— A genus con- 

 taining only the following species ; — 



C. sativa. — ^A vigorous Indian aimual, 

 often 4-10 ft. high in the British Islands, 

 but much taller in Italy and other parts 

 of S. Europe. It has alternate or, at the 

 very base, opposite stalked leaves, pal- 

 mately divided into 5-11 lance-shaped 

 acute serrate segments. Flowers in June, 

 greenish, inconspicuous, dioecious, the 

 male ones shortly paniculate, and having 

 5 distinct segments, the female ones 

 clustered between the sessile bracts. 

 Stamens 5. Achene flattish, within the 

 perianth. 



Culture and Propagation. — The Hemp 

 plant flourishes in ordinary garden soil, 

 and comes up freely from seeds sown in 

 the open border in April and May. It is 

 of far more value as an article of com- 

 merce (the stems yielding hemp) than as 

 a garden plant. StiU, when grown in 

 rich soil with plenty of room to develop, 

 it is by no means ungraceful, and gives a 

 somewhat tropical aspect to the garden. 



BROUSSONETIA (Paper Mul- 

 berry).— A genus containing two or 

 three species of milky trees with alter- 

 nate stalked slightly wrinkled and softly 

 hairy undivided or 3-5-lobed leaves with 

 lateral deciduous stipules. Flowers dioe- 

 cious, the male ones in cylindrical spikes 

 and having a 4-parted perianth, the female 

 ones in roundish heads with an ovoid or 

 tubular 3-4 -toothed perianth. Stamens 4. 



B. papyrifera. — An ornamental Chinese 

 shrub or small tree 10-20 ft. high, with large 

 lobed or entire hairy leaves and greenish 

 flowers in May, as above described. There 

 are several forms, differing chiefly in the 

 shape of the leaves, one called variously 

 laeiniata, dissecta, or heterophylla in 

 gardens, having the leaves very much 

 divided. 



Culture and Propagation. — In Nor- 

 thern parts this plant requires protection 

 in severe winters, but in the South it 

 seems to be practically hardy in warm 

 sheltered positions. It flourishes in rich 

 . loamy soU well enriched with manure, 

 and may be increased by suckers and
