SPECIES EILICUM.

Subord. VII.—SCOLOPENDRIEH3, Pr.

Sori as in Aspleniea (Subord. VI. vol. ii. p- 76), except thathe involucres are arranged in pairs, opposite to each other,°ne originating on the superior side of a veinlet, the other0,1 the inferior side of the opposite veinlet or branch .—-Asmall group, with one exception, having undivided fronds.Venation free, or more or less anastomosing.

I have ventured to unite under one genus Scolopendrmm, Sm., Anttgramme,Pr -> Camptosorus, Lk., and Schaffneria, Fee. The chief distinctions depend onthe nature of the venation, and, certainly, in proportion as the veins anastomose,the sori become scattered and the involucres are not always connivent in pairs,opening face to face. Mettenius excludes the group from Aspleniece, while Mooreincorporates the two.

1. SCOLOPENDRIUM, Sm.

(Hook. Gen. Fie. tab. LVII. B. Antigranune, Pv.Hook. Gen. Fil. tab. LVII. A. Camptosorus, Link. Hook.Gen. Fil. tab. LVIL C. Schaffneria, Fee.)

Character of the genus the same as the Suborder.

§ Euscolopendrium. — Veins free or occasionally anastomosing.

!• S. (Euscolopendriurn) vulgare, Sm.; caudex short erectstout scaly as well as the usually short tufted stipites, fronds6 inches to 2 feet long oblong-strapshaped moderately acutedeeply auriculato-cordate at the base, veins close parallel rarelyanastomosing. — Sm.
