Adiantnm continued. 



A. Caplllns-Venerls (Venus's hair).* Common Maidenhair, ati. 

 sub-erect, rather slender, 4in. to 9in. long, fronds very variable 

 in size, with short terminal and numerous erecto-patent lateral 

 branches on each side, the lowest slightly branched again ; seg- 

 ments iin. to lin. broad, deeply lobed, and the lobes again bluntly 

 crenated. aori placed hi roundish sinuses of the crenation. Great 

 Britain, and world-wide in its distribution. Greenhouse, case, or 

 frame species. 



A. C.-V. cornubiense (Cornish).* fronds very numerous, and 

 dwarf, more or less oblong in general outline, with large, broad 

 pinnules of a deep green, with finely-waved margins, and an 

 almost pellucid, but Inn texture. One of the best forms, but 

 somewhat delicate in constitution. 



A. C.-V. crispnlum (crisped).* fronds, with the stipes, from 

 6in. to 12in. long, more attenuated than those of the type, and 

 narrower at the base ; pinnules less numerous, but broad and thin, 

 crisp, of a light green colour, more or less cut at the broadest part. 

 A handsome variety, of vigorous growth. 



FIG. 26. ADIANTUM CAPILLUS-VENERIS DAPHNITES. 



A. C.-V. daphnltes (glistening).* sti. and rochises dark brown, 

 reaching a height of from 9m. to 14in. pinnae and ultimate 

 pinnules more or less confluent, the latter being broad, and of a 

 dull green colour, usually forming a tufted crest at the extremities 

 of the fronds. A charming subject for the Wardian case. Very 

 distinct. See Fig. 26. 



A. C.-V. flssum (divided). Very dwarf in habit, with pinnules 

 rather broader than those of the type, which are deeply and 

 variously cut, so as to give the plant a distinctive appearance from 

 most of the forms. 



A. C.-V. Foot! (Foot's). Closely allied to the variety fssum, 

 having fronds a foot or more long, with very ample pinnules 

 deeply incised, light green. Vigorous. 



A. C.-V. incisnm (deeply cut). Very closely allied to A. C.-V. 

 fesum, but rather more vigorous in growth ; pinnules broad, and 

 deeply slit into segments near the base. 



A. C.-V. magnificnm (magnificent).* fronds from 9in. to!6in. long, 

 more or less elongated in outline, 3in. to 4in. across ; pinnules 

 ample, rich green, with the margins finely cut and imbricated. 

 The arching character gives this form a most distinct appearance. 

 A very fine variety. 



A. C.-V. rotundnm (rounded). Pinnules usually round, without 

 the cuneiform base of the normal form ; neither are the fronds 

 so broad. Isle of Man. Variable in its habit 



A. C.-V. nndnlatnm (wavy).* fronds dense, compact, having 

 broad, roundish dark green pinnules, which are undulated at the 

 edges. An elegant dwarf -growing form. 



A. cardiochlaena (heart-form indusium). A synonym of A. poly- 

 phyllttm. 



A. caudatnm (tailed).* tti. 2in. to 4in. long, tufted, wiry, fronds 

 6in. to 12in. long, simply pinnate, often elongated, and rooting at 

 the extremity ; pinnae about iin. long, Jin. deep, dimidiate, nearly 

 sessile, the lower line straight and horizontal, the upper rounded, 

 more or less cut, the point usually blunt, the lower ones slightly 

 stalked, sori roundish or transversely oblong on the edge of the 

 lobes ; rochls and both sides of the frond villose. A. eiliatum

(of gardens) is probably a mere form, if not a synonym, of this 

 species. Throughout the Tropics everywhere. Greenhouse or 

 stove species ; very fine for hanging baskets. 



A. colpodes (deep hollow).* sti. 4m. to 6in. long, slender, slightly 

 fibrillose. fronds 9in. to 18in. long, 4in. to Sin. broad, deltoid, 

 tripinnate, light green ; lower pinnae spreading at right angles 

 from the rachis, 2m. to 4in. long, liin. broad, slightly branched 

 below ; ultimate segments about iin. long, Jin. broad, the lower 

 line often straight, the upper rounded, lobed, and toothed, all 

 nearly or quite sessile, sori placed in distinct teeth of the outer 

 edge. Ecuador and Peru, 1875. Greenhouse species. 



A. concinnum (neat).* sti. 4in. to Sin. long, fronds 12in. to 18in. 

 long, 6in. to Sin. broad, ovate-deltoid, tripinnate ; pinnae numerous, 

 spreading, flexuous, the lowest 4in. to 6m. long, 2in. to 3in. broad ; 

 segments Jin. to fin. across, broadly cuneate at the base, the 

 upper edge irregularly rounded, deeply lobed, the lobes crenate, 

 the lowest segment of each pinna and pinnule large, sessile, sori 

 numerous, ob-reniform. Tropical America. A most elegant 

 species for baskets and the rockery. 



A. c. Fleming! (Fleming's). This variety, of garden origin, if 

 also very handsome. 



A. C. latum (broad).* Differs from the type in being more erect 

 and robust in habit, and broader in all its parts. It constitutesan 

 excellent stove plant. 



A. orenatum (crenated).* sti. 6in. to 9in. long, fronds with a ter- 

 minal central pinna 6m. to 9in. long, and several large erecto- 

 patent lateral ones on each side, the lowest of which are branched 

 again ; segments about iin. long, Jin. deep, dimidiate, the 

 lower line upcurved, the upper nearly straight, slightly crenate. 

 sori numerous, round, placed on the upper and sometimes outer 

 edge. This is closely allied to A. tetraphyllum. Mexico. Stove 

 species. SY.N. A. Wtitsianum.

A. cristatnm (crested), sti. bin. to 12in. long, strong, erect, 

 tomentose. fronds lift, to 3ft. long, 9in. to 12in. broad, with a 

 terminal central pinna 6in. to 9in. long, lin. to liin. broad, and 

 numerous rather distant lateral ones on each side, the lowest of 

 which are sometimes again branched ; segments iin. to jin. long, 

 Jin. to fin. broad, dimidiate, the lower line nearly straight, the

 fronds 6in. to 12in. long, 2in. to 4in. broad, simply pinnate, or 

 with a single pair of short branches ; pinnae lin. to 2in.

(wedge-shaped).* sti. 6in. to Sin. long, slender, 

 erect, fronds 9in. to 18in. long, 6in. to 9in. broad, deltoid, tri- or 

 quadripinnate ; lower pinnas 4m. to 6in. long, 2in. to Sin. broad ; 

 segments numerous, Jin. to |in. broad, cuneate at the base, the 

 upper edge deeply lobed. sori four to six, obversely reniform. 

 Brazil, 1820. This fine greenhouse species is more generally 

 grown than any other; and a number of garden forms have received 

 distinctive names.
