Note 21 — DIVISION III. PTERIDOPHYTA (VASCULAR CRYPTOGAMS).

Floral-leaves (hypsophyllary leaves) are here adopted as an equivalent of the term “Hochblätter,” to signify leaves on the floral-shoot other than foliage or sporangia-bearing leaves. The term bract is applied only to leaves in whose axil a flower is borne, and bracteoles to leaves borne on the flower-stalk (pedicel).
