THE FLORAL WORLD AND GARDEN GUIDE. 
that no stoppage occurs. Plants intended for specimens must be 
repotted as they require it. Orchids and ferns may be re])otted and 
separated where desirable ; Poinsettia pulcherrima, and Kuphorbia 
jacquiniflora may be taken to the greenhouse if the temperature 
there ranges about 50 degs., and a few achimines and gloxinias may 
be put in heat for early blooming. Cucumbers and melons for early 
use should be got in at once. Average temperature of the stove 
this month, 60 degs. A temperature of 50 degs. night, and 60 degs. 
day, will bring on roses, daphnes, lilacs, weigelias, kalmias, azaleas, 
double plum, almond, and peach, and other of the showy spring 
flowers, with very little trouble. Keep a moist air, and beware of 
crowding. 
NEW BOOKS. 
OST important among recent horticultural books is a hand- 
some volume entitled The Clematis as a Garden IPloicer. 
By Thomas Moobe, P.L.S., and Geobge Jackman, 
of the Woking Nurseries (Murray). In the Ploeal 
W oELD for May, 1871, we presented a coloured figure 
of one of the new hybrid clematis, and gave some account of 
them and their decorative uses and cultivation. The new and 
attractive work by Messrs. Moore and Jackman will be found in- 
tensely entertaining and permanently useful to those of our readers 
who have made themselves acquainted with the merits of these 
flowers, and we may as well add that those who have hitherto 
neglected them may insure for themselves a new and expansive 
pleasure by securing the treatise, and making it subservient to an 
hour of intellectual pastime, while the nights are long, and the fire- 
side the safest haven. In a substantial octavo, the authors have 
presented a full account of the clematis family, and of the rise and 
progress of cross-breeding, which has resulted in the production of 
a superb group of garden flowers, which have the threefold merit of 
perfect hardiness, long continuance of display, and the production 
of floral colourings much needed to complete the chromatic harmony 
of garden scenes. In red and yellow shades we are rich ; in blues 
and purples, poor ; that is to say, we were poor ; but the clematis has 
made lis rich in this department also, and not a few of the new 
varieties are entitled to be regarded as the most gorgeously coloured 
of any of the many subjects available for outdoor display in the 
summer season. Moreover, these are not only bedding plants in the 
properest sense of the word, that need no protection of glass during 
the winter, but are remarkable for grandeur when properly grown 
in pots for the conservatory, or employed to cover walls and trellises 
with their light twining and fast-growing stems, and huge salver- 
shaped flowers of purest white, intensest purple, softened crimson, 
or full cobalt blue. The book before us treats in the amplest manner 
of the cultivation of the plants, as well as of their botanical rela- 
tionships and garden history, and it is a perfect guide to the selection 
of varieties for whatever purpose the cultivator may require them.
