longer witlioiit change or addition of soil, 

 but the experiment was cut short through 

 unforeseen circumstances. 



If it is thouglit advisable to grow some 

 on to a larger size, they should when done 

 blooming be moved into pots proportionate 

 to the size they are wanted tu grow to, say 

 9 or 10 inches the first year ; but for 

 geneial use, to produce plants to flower in 

 a small state with single heads, nothing 

 equals the appearance of the autumn-struck 

 cuttings that have been produced out-of- 

 doors, for which the above two forms of H. 

 hortensis are the best adapted. 



The variegated forms of H. japonica, H. 

 japonica argentea variegata, and H. japo- 

 nica aurea vaiiegata, are well worth cultiva- 

 tion for the beauty of their leaves, as well 

 as the flowers they produce. 



H. Otaksa. A very fine variety with 

 large flowers, also suitable for pot-culture, 

 like those alreadj^ described, and of easy 

 cultivation ; it is propagated from half-ripe 

 shoots and grown in ordinary soil, either 

 l^eat or loam, with one-eighth sand to keep 

 such thirsty subjects from getting sour and 

 waterlogged ; the plants should be exposed 

 in the after part of summer in the open 

 air to keep them dwarf and to get the wood 

 ripened. 



H. 'paniculata. A white-flowered beauti- 

 ful species that does well under pot- 

 culture ; it is a most profuse free-blooming 

 plant, that deserves to be generally known 

 and much more generally grown than it is. 



H. stellata Jlorc-plena. Another fine 

 Japanese variety, producing very large 

 corymbs of double rose-coloured flowers, 

 and is in every way a desirable plant ; 

 treatment same as for the preceding. 



JS. Thomas Hogg. A very handsome 

 kind that has recently appeared. It is a 

 free-llowerer, producing moderate -sized 

 heads of white flowers. 



The system of propagation and general 

 treatment advised for the other species will 

 answer for these, except that where the 

 plants are requu'ed to be grown to a con- 

 siderable size they must be encouraged by 

 more jaot-room. 



With less trouble Hydrangeas may be 

 struck from cuttings produced in sjii-ing 

 from plants that have been flowered i-arly ; 

 these should be taken off' when they have 

 three or four joints, and put singly in 

 3-inch pots filled with half sand and loam. 

 Stood in an intermediate heat, kept close, 

 moist, and shaded, they will root in a few 

 weeks, when give more air and as soon as 

 the pots are fairly filled ^\^th roots put in 

 others from 6 to 8 inches in diameter, 

 using good loam, well enriched with rotten 

 manure and with some sand added. When 



well established in these move to the open 

 air, and give Avater as required through 

 the summer ; keep in a pit or frame away 

 from frost during the winter until required 

 for forcing, or in the greenhouse to come 

 on with solar heat for later blooming. 



Insects. — Hydrangeas are not much 

 troubled with insects, except greenfly, 

 which can be kept under by fumigating, 

 dipi^ing, or syringing with tobacco water 



HYMENODIUM CRINITUM. 



A small-growing very distinct stove 

 Fern ; the fronds are simple, that is with- 

 out any divisions and about the size of a 

 moderate example of Horse-radish, the 

 surface studded over with black hairs. It 

 is not elegant, but is desirable on account 

 of its dissimilarity to other Ferns. It 

 comes from the West Indies. 



For propagation and cultivation, see 

 Ferns, general details of culture. 



HYMENOPHYLLUM. 



A beautiful genus of dwarf-spreading 

 Filmy Ferns, lequiring cool treatment, and 

 to be kept always moist at the roots, and 

 also in a moist atmosphere, such as present 

 when covered with a bell-glass. They do 

 not like much warmth, nor very much 

 light.

IMANTOPHYLLUM. 



These are fine flowering evergreen green- 

 house plants of close compact growth, that 

 may be had in bloom during a good por- 

 tion of the year where there is a sutficient 

 quantity to keep up a succession. They 

 force well, and on this account can be 

 brought into flower during the winter so 

 as to precede such as are let to come on 

 later in a greenhouse temperature. The 

 flowers are produced in large umbels on 

 erect fleshy stalks tliat issue from the 

 crowns among the leaves ; they are a
