SCOLOPENDRIUM. 339 



S. Y. subpinnatum — sub-pin-na'-tum (somewhat pinnate), Moore. 



A singular, dwarf variety, originally found at Ilfracombe, with fronds 

 6in, long, Sin. broad, and split to . the midrib into several irregular, rounded 

 lobes, wedge-shaped at the base. — Lowe, Our Native Ferns, ii., fig. 611. 



S. Y. SUpralineatum — sup-ra-lin-e-a'-tum (lined above), Moore. 



In this very distinct form, which was originally found at Settle, in 

 Yorkshire, and eventually in various parts of England, the fronds. Gin. to 

 12in. long and lin. to 2in. broad, have an excurrent membrane developed on 

 their surface. Their base is usually heart-shaped, their extremity blunt or 

 somewhat lobed, and the margins, which show on each side an interrupted, 

 membrane-like line, irregularly lobed or toothed, are occasionally wavy. — Lowe, 

 Our Native Ferns, ii., fig. 620. 



S. Y. suprasoriferum — sup-ra-so-rif'-er-um (bearing sori above), Lowe. 



A most singular and interesting form, with fronds of normal dimensions, 

 being 1ft. or more long and lin. to 2in. broad, notched along the margins, and 

 bearing spore masses on their upper as well as on their under surface. It 

 has been found in many localities in Great Britain. — Lowe, Our Native 

 Ferns, ii., t. 56a. 



S. Y. undulato-ramosum — un-dul-a'-to-ra-mo'-sum (waved and branched), 

 Lowe. 

 A fine variety, of large dimensions, with wavy fronds much branched at 

 their summit, each branching portioji being again conspicuously wavy. It 

 was originally found in Devonshire. — Lowe, Our Native Ferns, ii., fig. 623. 



S. Y. undulato-rigidum — un-dul-a'-to-rig'-id-um (rigidly wavy), Druery. 

 This stifi^-growing form of S. v. crispum is thoroughly distinct on account 

 of its being constantly fertile. Its greatest claim to cultivation, however, lies 

 in the fact that its spores invariably yield a proportion of the beautiful 

 aS'. v. crispum fimbriatum. — Druery, Choice British Ferns, p. 143. 



S. Y. undulatum — un-dul-a'-tum (wavy), Moore. 



This is a pretty form, allied to S. v. crispum, with regularly wavy fi-onds 



of a less crispy nature, narrower, and distinct in being always fertile. — Lowe, 



Our Native Ferns, ii., fig. 654.
