ACACIAS.--Australia. In Cornish and South Devon gardens many species are to be met with in robust health. _A. affinis_, very generally confounded with _A. dealbata_, is the most common. In many cases _A. affinis_ is grown as _A. dealbata_. The leaves of the former are green, while those of the latter are bluish and its flowers are less bright in colour. A group of _A. affinis_ about 35 feet in height was a wonderful sight at Tregothnan at the end of March, being simply covered with golden blossom which was thrown into high relief by a background of Ilexes. _A. verticillata_ is another handsome species flowering later in the spring. It is a very rapid grower, reaching a height of 15 feet in a few years, generally growing in the form of a broad-based cone, with its lower branches but a foot or so from the ground. When in flower it is so covered with its pale-yellow blossoms that no foliage is discernible. _A. armata_ may be seen as a bush 7 feet high and as much in diameter. _A. ovata_ Mr. Fitzherbert has only seen as a bush some 3 feet high; very pretty when bearing its circular, golden flower-bells. _A. longifolia_ is another handsome tree, with leaves something like those of an Oleander and bright-yellow flowers. _A. melanoxylon_ is a fine tree. The specimen at Tresco is about 50 feet in height, and there are good examples on the mainland. Pale-yellow flowers produced in profusion. Other species met with are _A. riceana_, _A. (Albizzia) lophantha_, _A. calamifolia_, _A. linifolia_, _A. latifolia_, and _A. platyptera_, the latter against a wall.
ADENANDRA FRAGRANS.--Cape of Good Hope. A small evergreen shrub, bearing fragrant, rose-coloured flowers. Tregothnan.
ANOPTERUS GLANDULOSA.--Tasmania. A vigorous evergreen shrub, with dark, shining green leaves, bearing long, erect terminal racemes of white, cup-shaped flowers, resembling the blooms of _Clethra arborea_, but larger. Tregothnan.
ACANTHOPANAX SPINOSUM.--Garden seedling. A striking plant with dark-green, large-sized leaves divided into five sections. Height at present 5 feet. Tregothnan.
ASTER (OLEARIA) ARGOPHYLLUS.--Australia. The Silver Musk tree, with musk-scented leaves and dull-red flowers in summer. Three gardens. Height 12 feet.
