ADIKE. A synonym of Pilea (v^rhicli see). 



ADINA (from adinos, crowded; in reference to tho 

 flowers being" disponed in heads). Ord. Rithiarece. A very 

 pretty evergreen cool stove shrub, with opposite tereto 

 branches, and solitary, axillary peduncles. It thrives iu 

 a mixture of loam, sand, and peat. Propagated by cutting.s, 

 inserted in a rich, loamy soil, under a hand glass, in boat.

 collected into jili.bosc heads ; corolla funiud slin]ieil ; peduncles

 longer than the peduncles. /(. 3ft. to'aft. China, 1804. 



ADIiUMIA (from adlumino, to fringe with purple ; 

 flowers bordered with purple). Ord. Funiariareoj. An 

 interesting, delicate, and nearly hardy climber from North 

 America. Flowers with four spongy, cohering petals. A 

 warm, good soil is moat suitable ; sow seeds about May in 

 a shady spot. It is a biennial, hut in favourable spots is 

 self-sowing, and thus may be treated as a perennial. If 

 placed either against a wall or in the open it is a pretty 

 subject for trailing over a shrul> or twiggy branch. From 

 its fragile character, it can only be seen to tho best advan- 

 tage under glass.

 peduncles axillary, generally four-Howered. June. /. triply ])in- 

 nate, pale green, h. 15ft. 1788. 'J'he Maidenhair fern like leaves 

 are borne in profusion on the slender twining stems. Svn. Cory-

ADNATI!. Grown to anything by the whole surfaee ; 

 anthers are said to be Adnate when they are attached to 

 the filaments by their whole length. 



ADONIS (name of classical derivation). Ord. Rfinun- 

 culacem. Handsome hardy herbaceous plants. Flowers 

 solitary, terminal : petals five to fifteen. Leaves divided 

 into numerous linear segments. Some of the annuals are 

 much inferior to the perennial species. The latter section 

 constitute very ornamental subjects for rockwork, borders, 

 margins of shrubberies, &c. All the species will grow 

 freely in common soil, and are propagated by seeds. The 

 perennials may be divided at the root. 



A. aestivalis (sunnner).* Pheasant's Kye, ^. deep crimson ; 

 petals flat, oblong, obtuse, onedialf longer than the calyx. June. 

 Stem almost simple, elongated, k. 1ft. South Europe, 1629.
