generally blooms in the Spring, but may sometimes be found Acacias 
in flower as late as the end of June. 4. longifolia is so named 
from its leaves, which are eight inches in length. Its blossoms 
are borne in cylindrical spikes. ‘There are many fine specimens 
in Cornwall, which are very pretty when in flower. This 
Acacia sometimes refuses to bloom, but the variety /loribunda 
flowers freely in all cases. 4. melanoxylon attains a height of 
forty feet or more, and bears pale yellow flowers in great pro- 
fusion. Its leaves are long and lance-shaped. 4. Drummondi, 
a popular conservatory plant, bears tubular spikes of pale yellow 
flowers. 4. Riceana is the most graceful in habit of all the 
Acacias, its slender shoots drooping at their extremities. Its 
foliage is thin and wiry, and its pendent, cream-white flower- 
clusters are abundantly borne at the extremities of the thin, 
arching shoots in the month of May. Although a native of 
Tasmania, and therefore, probably, hardier than many other 
species, its growth unfits it for any position where it is exposed 
to the wind. 4. cordata is rare in gardens, and somewhat 
resembles a Heath. Its small flowers are almost white, and its 
long, slender shoots are furnished with sharply-pointed leaves. 
A. lopantha is another well-known greenhouse plant, and is 
sometimes used in sub-tropical bedding. Its foliage is very 
elegant. It is more tender than most species, several being 
killed during the past severe winter, though some are still 
alive. Its greenish-yellow flowers are borne in the winter. 
A, cultriformis and A. platyptera are two climbing species 
that must be grown against a wall. Other species cultivated 
in Cornwall are 4. calamifolia, A. diffusa, A. latifolia, A. 
linifolia, and A. paradoxa. 
The most splendid of all flowering trees is without doubt
