Proteacee. A genus comprising two or three species of 
tall, greenhouse shrubs, endemic in Australia. Flowers 
red, showy, on twin pedicels, densely racemose ; perianth 
slightly irregular, the tube open early on the under side, 
tapering and recurved under the limb, the laminz oblique, 
broad ; racemes terminal, sub-globose or ovoid, surrounded 
by an involucre of imbricated, coloured bracts, the bracts 
within the raceme small.  Follicles stipitate, oblique, 
recurved, Leaves alternate, entire or toothed. T. specio- 
sissima, the only species yet introduced, is one of the 
most beautiful plants in the order to which it belongs. 
It requires a temperature rather warmer than that of 
an ordinary greenhouse; but a very moist atmosphere 
encourages a too vigorous growth, which is not con- 
ducive to floriferousness. Water may be applied freely 
in summer, but the roots should be kept nearly dry in 
winter. A well-drained border or bed of sandy loam is 
most suitable for the reception of this plant. Propa- 
gated by layering suckers during winter, in small pots, 
and allowing them to remain until rooted in the pots 
before being detached.

‘TEMPERATURE. A study of the ever-varying Tem- 
peratures daily experienced, and their effect. on cultivated 
plants, forms an important part of the duties of every 
gardener who has under his charge anything beyond 
that which is of the hardiest description. Temperatures, | 
it need scarcely be remarked, often fluctuate very suddenly 
from what is called one extreme to the other; and, as 
their guidance is beyond human control, it becomes a 
necessity on the part of cultivators to prevent such 
changes, so far as possible, from injuriously affecting 
plants, by giving constant attention, and anticipating what | 
is likely to ensue. The degree of intensity of heat or cold 
1s ascertained by the expansion or contraction of the 
mercury or spirit in a thermometer. From knowledge 
gained by experience, the extreme Temperatures that a 
number of plants will withstand with impunity is 
often known, but there are exceptional cases where other 
conditions are unfavourable, and plants succumb in spite 
of all precautions. To know the Temperature in which 
various exotics succeed best, and the proper degree of heat 
requisite for bringing them to perfection, is one of the first 
essentials towards success. The maintenance of an equable 
Temperature in forcing operations, and in the culture of 
fruits under glass, is of great importance, as on it depends 
most materially the development of fruit or flowers, as the 
case may be. Forcing indoors is most intimately con- 
nected with, and dependent upon, the regulation of Tem- 
perature by means of the heating apparatus and the 
Temperature—continued. 
essential for good gardening, and, even when these are 
intelligently exercised in daily management, the operator 
finds there are many things beyond his control, sudden 
changes in the Temperature being amongst the most 
formidable. 
_ TEMPLES. Architectural buildings, usually erected 
in extensive pleasure-grounds to form distinct, attrac- 
tive features in themselves, and sometimes to afford 
resting-places or places of shelter. Temples found in 
many extensive gardens that have long been established, 
built of similar massive material, in proportion, to that 
of the mansion, are the best to imitate when this style 
of embellishment is desired. In any case, the material 
used should be of the most durable description; the 
shapes most generally adopted are circular, octagonal, 
and oblong. Occasionally, an elevated point or some 
position at the end of a walk will present itself, and 
appear to indicate the very place for a Temple, but 
these buildings need be, as a rule, but sparingly intro- 
duced. They are invariably éxpensive to erect. 
TEMPLETONIA (named in honour of John Tem- 
pleton, an Irish botanist), Including Nematophyllum. 
ORD. Leguminose. A genus embracing seven species of © 
Australian, glabrous, greenhouse shrubs or under-shrubs, 
occasionally leafless. Flowers red or yellow, axillary, 
solitary or two or three together; two upper calyx 
lobes or teeth united or Yrarely distinct; standard or- 
bicular or obovate, usually reflexed; wings narrow; 
stamens all united in a sheath open on the upper side; 
bracts usually very minute. Leaves (when present) 
alternate, simple, entire; stipules minute or spinescent. 
T. retusa, the only species introduced, is an interesting 
plant, thriving in a mixture of sandy loam and peat. 
It may be increased by young cuttings, inserted in sand, 
under a glass.
