AItTABOTIt7S (from artao, to suspend or support, 

 ami })!>{ iifs, tjrapos ; in rcferonce to tlio way tho fruit is sup- 

 ported by the curious temlvil). *>kd. Anonorfw. A hand- 

 some stove evergrreen siu*ul), thriving- in a good sandy loam 

 and peat, to which a little rotten duny may bo added. 

 Propagated l>y cuttings made of ripened wood, insert 

 in sand under a bell glass, with bottom heat, in early 

 spring. Seed, when iirocui-able, should be sown as soon 

 after receipt as possible. 



A. odoratissimus (sweete.st-Rcenteil).* ./?. n-iliUsh Itrowu, ex- 

 ttemely fragiaiit ; i»e(Unules oiiiiiisiti- the leaves, iMmkcil beneath 

 the niiildle. .lune and July. /. nliluiig him-eolati-, aeiiiinuateil, 

 Hiuoiith, shiTiiii,^. /(. 6ft. Malayan Islands, 1758. In Java, the 

 leaves are held to be iiivahiable as a pieventivu ul cliuleia. 



ARTANISMA (from arlao, to support, and neina, a 

 Hhiment; in reference to a tooth-like process growing on 

 the longer filaments). Ord. Scrophnlarinp.ee. An inte- 

 resting and handsome greenhouse evergreen shrub, allied 

 to Turenui. Flowers disposed in terminal racemes, and 

 on short pedicels. Leaves opposite, sub-serrated. It may 

 be treated as hardy dui'ing summer, for which piu'pose 

 seeds should bo sown in spring ; but it requires tho pro- 

 tection of a grcenliouso during winter. Artanema grows 

 freely in light rich soil, and is readily increased by cut- 

 tings and seeds.

 shaped, clothed with nihuite yUmdnlar pubescence outside ;

 Compositm. A very largo genus of mostly hardy herba- 

 ceous perennials, few of which, comparatively speaking, 

 are worth growing. Fiower-heads disposed in spikes, or 

 racemes, and these are usually arranged in i)anicles ; pappus 

 none ; involacr« few-flowered, ovate or rounded, imbri- 

 eated ; florets of tho disk all tubular; of the ray, if 

 any, slender, awl-shaped. Leaves alternate, variously 

 lobed. All the species are of the easiest possible culture 

 in any dry soil. The shrubby kinds are best propagated 

 by cuttings; the herbaceous ones, by dividing at the root; 

 and the annuals, by seeds.
