 ment. Columbia, 1866. A magnificent stove species.

 glossy, frondt 6in. to 12in. long, 4in. to Sin. broad, deltoid, 

 tri-quadripinnate ; ultimate segments about Jin. across, cuneate at 

 the base, the upper edge rounded, and usually finely toothed, of 

 a light green colour, with a firm texture, tori one to three, 

 roundish ; in hollows of the upper edge. Himalayas, up to 8000ft. 

 Greenhouse or frame, nearly hardy in sheltered places. SYX.

A. villosum (hairy stalked).* tti. 9in. to 12in. long, strong, erect. 

 frondt with a terminal central and several spreading pinnae on 

 each side, 6in. to 12in. long, 1 2 in. to 2in. broad ; pinnules di- 

 midiate, about lin. long, iin. broad, the lower line nearly straight, 

 the upper edge nearly parallel with it, but considerably larger, 

 slightly toothed, and the outer edge auriculed at the base, tori 

 in a continuous line round the upper and outer edge. West Indies, 

 Ac., 1775. Stove species. 



A. Wagneri (Wagner's). Synonymous with A. decorum. 



A. Wilesianum (Wiles's). Synonymous with A. crenatum, 



A. Williamsil (Williams's).* tti. (an. to Sin. long, frondt 9in. to 

 18in. long, tripinnate, triangular ; pinnae ovate, distant, pinnules 

 sub-rotund, slightly trapezif orm, the basal line rather concave, the 

 margin entire or slightly undulated, or divided into three to four 

 lobes, crenately notched between the sori, the sterile portions with 

 an erose diaphanous margin, tori eight to ten, elongate reniform 

 or lunate, occupying the whole of the semicircular outer edge. 

 Mountains of Peru, 1877. In a young state, the stipes and fronds 

 are dusted with a yellow powder. This is one of the most beauti- 

 ful of the Maidenhair ferns. Greenhouse species. 



A. Wilaoni (Wilson's).* tti. 6in. to 12iiL long, erect, frondt 9in. 

 to 12in. long, 6in. to 12in. broad, simply pinnate, with a large 

 terminal pinna and two to six sub-sessUe lateral ones on each 

 side, which are 4in. to 6in. long, lin. to 2in. broad, ovate or ovate- 

 lanceolate, acuminate, nearly entire, sori in continuous lines along 

 both edges. Jamaica. Stove species. STSS. A. dolotum, A. 

 tnacropterum. 



A, Zn.^Ti (Zahn'a). Synonymous with A. Seemanni. 



A synonym of Pilea (which see). 

 ADINA (from adinos, crowded; in reference to the 

 flowers being disposed in heads). OBD. Rubiaceoe. A. very 

 pretty evergreen cool stove shrnb, with opposite terete 

 branches, and solitary, axillary peduncles. It thrives in 

 a mirtnre of loam, sand, and peat. Propagated by cuttings, 

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

 A. globlfera (globe-bearing).* JL yellowish, sessile, crowded, 

 collected into globose heads ; corolla funnel-shaped ; peduncles 

 axillary, rarely terminal, solitary. July. L lanceolate, glabrous, 

 longer than the peduncles. A. 3ft. to 4ft China, 1804. 

 ADLUMIA (from adlumino, to fringe with purple; 

 flowers bordered with purple). OBD. Fumariaceas. An 

 interesting, delicate, and nearly hardy climber from North 

 America. Flowers with four spongy, cohering petals. A 

 warm, good soil ia most suitable ; sow seeds about May in 

 a shady spot It is a biennial, but 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 tailing over a shrub or twiggy branch. From 

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

 tage under glass. 



Adonis continued. 



A. antnmnalla (autumnal).* Pheasant's Eye; Bed Morocco. 

 JL of an intense blood-red, with a black centre, rarely pale, 

 globose from the six to eight concave conniving petals, which 

 are scarcely larger than tue calyx. May. Stems branched. 

 h. 1ft Britain. Annual 



A. pyrenaica (PyreneanX* /. almost sessile, yellow ; petals eight 

 to ten, smaller and more obtuse than in A. oerruUu. July. 

 I., lower ones on long stalks, with trifid petioles and many-parted 

 segments ; upper ones sessile, multifid, with linear very entire 

 lobules. Stem 1ft or more high, and usually much branched. 

 Pyrenees, ' 



A. drrHoea (tendrffled).' fl. pale rose-coloured, about Jin. long ; 

 peduncles axillary, generally four-flowered. J 

 nate, pale green, h. 15ft 1788. The Maidenhair 

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



ur-flowered. June. I. tn

 dates fungota. 



ADN ATE. Grown to anything by the whole surface ; 

 anthers are said to be Adnate when they are attached to 

 the filaments by their whole length. 



ADONIS (name of classical derivation). OBD. Ranun- 

 eulacecB. 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, Ac. All the species will grow 

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

 perennials may be divided at the root. 

 A. aestivallfl (summer).* Pheasant's Eye. Jl. deep crimson; 



petals flat, oblong, obtuse, one-half longer than the calyx. June. 



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



Annual. See Figs. 31 and 32. 



Fio. 31. FLOWER OF ADOMS .SSTIVALIS. 



A. vernalis (spring).* /. yellow, large ; petals, ten to twelve, oblong, 

 rather denticulated. March. L lower ones abortive, or reduced 

 to somewhat sheathing scales, the middle and upper ones sessile 

 and multifid, with very entire lobes. A. 9in. to 1ft Europe, 

 1629. Charming rock plant. This handsome species requires a 

 rich moist sandy loam, and should not be disturbed for years. 

 Perennial.

 leaves are termed adult.
