AGONIS (from agon, a gathering, a collection; in 
allusion to the number of the seeds). . Syn. Billiottia. 
Orv. Myrtaceew. 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. 
flewuosa and A. marginata are rare in this country, but are 
grown at Kew. They should be firmly potted in a compost 
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. hk. (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. J. coriaceous, slightly hairy, in other respects like 
those of the common Box. Branches twiggy, numerous, the 
youngest ones silky-hairy.
