37. ADIANTUM. § 1. EU-ADIANTUM. 239 



narrow hyaline line. Texture coriaceous; upper surface finely copper- 

 coloured when seen by oblique light; veins terminating in the sinuses 

 between the ultimate serratures. Sori large, 1 —2 on a leaflet, transversely 

 oblong; sporangia confined to the veinlets. - . 



Sibuyan Island. 



(24) A. tinctum, Moore. 



This species is construed as including two forms: A. tinctum Moore 

 and A. decorum Moore. 



(24«) A., tinctum, Moore; A. Wagneri, Mett. (not Hk. Bk.), 

 Kuhn, in Linn., XXXVI, 77. 



Fronds 2-pinnate ; leaflets shallowly lobed on the outer edge. 



(2ib) A. decorum, mioove; A. Wagneri, Hk. Bk. (not Metf.), Syn. 

 Fil., 473. 



Fronds 3 — 4-pinnate; leaflets distinctly lobed on the outer edge. 



(25) A. cuneatum, I^.^F.; — var. variegatum, in Hort. Bog. 

 War. variegatum: Leaflets ornated with flabellate-spreading 



white stripes irregular in length. 



(26a) A. Fergusonii, Moore, Nich., Diet. d'Hort., I, 55. 



Stipes long, purplish-black, naked, glossy, as are the rachises. Fronds 

 middle-sized, triangular to ovate, 2 — 4-pinnate at the base, simply pinnate 

 at the apex, the terminal leaflet often deeply incised, with the segments 

 lobed again, as are the terminal leaflets of the branches und branchlets. 

 Pinnulae mostly with 1 — 5 leaflets on each side below the terminal one, 

 the lowest of which are not rarely deeply pinnatifid or even pinnate 

 again. Leaflets different in shape, sessile or stalked, mostly large, ovate, 

 rounded or obtuse, truncate to cuneate at the base, with the stalks 

 adherent to the rachises ; terminal leaflets of fronds branches and branchlets 

 the largest, the segments (penultimate lobes) not rarely conspicuously 

 imbricating. Texture thin but firm; veins terminating in the ultimate 

 crenations or serratures. Sori transversely oblong, terminal on the 

 ultimate lobes, slightly curved, placed in slightly rounded, shallow hollows, 

 the sporangia originating from the veins only. — Perhaps a garden 

 variety of another species. 



Much cultivated.
