1900 SUPPLEMENT—RECENT INTRODUCTIONS, &C. 29 
Ageratu-n—continued. 
Few bedding-plants are superior to Ageratums alike as 
regards their freedom, colour of flowers, and the time over 
which their beauty extends. Frequently they are the last 
of the summer occupants of beds and borders to succumb 
to frost; while they aré most useful in providing cut-flower 
material throughout the season. Where it is not desired 
to utilise them as bedding-plants they may be effectively 
employed as edgings—the Imperial Dwarf Azure and the 
Imperial Dwarf Blush White being very suitable on account 
of their compactness of habit—a quality which is wanting 
in some few of the garden varieties.

ing should be added :

AGNUS-CASTUS. See Vitex Agnus-castus. 
AGONIOPTERIS. See Acrostichum. 
AGONIS (from agon, a gathering, a collection; in 
allusion to the number of the seeds). Syn. Billiottia (of 
Brown). Orp. Myrtacew. A genus comprising ten species 
of greenhouse, evergreen shrubs or small trees, natives of 
West Australia. Flowers rather small, sessile, in dense, 
globose, axillary or terminal heads; calyx segments five, 
often scariose; petals five, spreading; stamens free, 
sometimes ten, opposite and alternate with the petals, 
sometimes twenty or more; bracts imbricating, often 
involucrate. Leaves alternate, often crowded on the 
branchlets, small or narrow and _ coriaceous, entire. 
A. flexuosa and A. marginata are rare in this country, but 
are grown at Kew. They should be firmly potted in a com- 
post of turfy loam and peat, with a liberal addition of sand. 
Water must be frequently given during the growing season. 
but more sparingly during winter. In autumn the plants 
may be placed in a sheltered and sunny position, to ripen 
their wood and induce the formation of buds. In the 
South of England these plants may prove hardy. Pro- 
pagation may be effected by cuttings of the half-ripened 
shoots, inserted in sandy peat, under a bell glass. 
A. flexuosa (flexible). .-heads white, axillary, surrounded by 
broad bracts, which, with the numerous long, white stamens, are 
the most attractive features of the inflorescence. Summer. 
1. lanceolate, like those of the Willow, smooth, dark green, the 
margins tinged with purple. A. (in Australia) 40ft.; may be 
limited to the size of a small pot shrub. (Gn. xxix. 534.) 
A. marginata (margined). (l.-heads white, axillary and terminal, 
about twenty-flowered ; petals small; stamens long, hair-like. 
Summer. /. coriaceous, slightly hairy, in other respects like 
those of the common Box. Branches twiggy, numerous, the 
toy ones silky-hairy. Syn. J'abricia stricta. (L. B. C. 
AGOSERIS. A synonym of Troximon (which see). 
AGRICOLA. A synonym of Clerodendron 
(which see). 
AGRILUS. Orv. Coleoptera. Out of some 500 
known species only five are found in Britain. They 
usually inhabit the stems of young Beech; but one species, 
a most beautiful insect, is credited with inflicting damage 
upon Roses. It is, however, such a rare insect that the 
likelihood of a severe attack is very remote. 
AGRIOTES. Orv. Coleoptera. To this genus belong 
several most destructive species in the garden, as their 
larve, together with those of a few others, are popularly 
known as ‘“ Wireworms.” The worst offenders are 
A. sputator, tin.; A. obscurus, }in.; and A. lineatus, }in. 
The female beetles deposit their eggs, which are of a 
dirty white, either in the soil close to the food-plants 
on which they have elected the larve when hatched 
By Permission of the Board of Agriculture.
