ABIES. 
Several species have been tried, but only A. alba, A. balsamea, 
A. cilicica, and A. Pinsapo are doing well. 
The latter species is generally reported as inhabiting the Sierra 
Nevada, but the tree does not occur there ; its real habitat* being 
the Sierra de Ronda and the Sierra de las Nieves between Cadiz 
and Malaga. 
ACACIA. 
Most of the Australian species grow very well. A great number 
were already planted in the autumn of 1867, procured from nur- 
series in Hyéres; others were received from Villa Thuret, Antibes. 
Some species, such as A. dealbata, A. decurrens, A. harpophylla, 
and A. melanoxylon, are long living trees with excellent hard wood, 
the last-named forming a fine erect stem. Most other species, for 
instance, A. cyanophylla, A. longifolia, A. armata, A. cyclopis, &e., 
do not attain any considerable age. A. dealbata, A. Baileyana, 
A. podalyriefolia, and several other species dislike calcareous soil, 
and are therefore generally grafted on A. retinodes. 
A. Hanburyana is a hybrid between A. dealbata and A. podaly- 
rvefolia. It has an elegant erect growth and is bluish-glaucous 
throughout. A. De Newfvillec and A. Siebertiana are hybrids 
between A. pycnantha and A. podalyriefolia. The former has 
narrow, strangely twisted leaves. 
These three hybrids originated in Mr. L. Winter’s gardens at 
Bordighera. 
The following species (commonly called ‘‘ Mimosa’’) are now 
extensively planted on the Riviera for the exportation of their 
flowers :—A. dealbata, A. pycnantha, A. cultriformis, A. podalyria- 
folia, A. obliqua, and A. Baileyana. 
A. spherocephala. 
Seeds of this plant were sent to us by Dr. Hermann Ross, 
Keeper of the Royal Herbarium, Munich, who collected them 
during the summer of 1906, near Mirador, in Mexico. So far the 
plants, though quite hardy, are small and have not yet flowered. 
From the form of the spines it seems to be this species rather 
than the very similar A. spadicigera. Both species have long been
