AGONIS (from agon, a gathering, a collection; in 

 allusion to the number of the seeds). Stk. Bllliottia. 

 Orb. Myrtacem. 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 ^yOf spreading ; stamens free 

 sometimes ten, opposite and alternate with the petals, 

 sometimes twenty or more i bracts imbricating, often 

 involucrate. Leaves alternate, often crowded on the 

 branchlets, small or narrow and coriaceous, entire, A. 

 fiexuosa 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 dnring 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). A.-hcads white, axillary, surrounded by 

 broad bracts, wliich, with the numerous long, white stamens, are 

 the most attractive features of the inflorescence. Summer. 

 {. 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). Jl.'heads white, axillaryand 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 

 youngest ones silky-hairy.

 thirty, and are distributed over extra-tropical regions. To 

 those described on p. 45, Vol. I., the following variety 

 should now be added ;
