ノキシノブ属と Pleopeltis の脈理

概要

論文の詳細を見る
Venation of Lepisorus, Pleopeltis and 10 genera allied to them was observed in various stages of juvenile leaves, and the developmental patterns were compared with one another. Included veinlets are regularly recurrent only and the lowermost veinlets (costules) start from lateral veins (costae) catadromously in Lepisorus, while, in juvenile leaves of Pleopeltis percussa (CAV.) HOOK. et GREV., the included veinlets are mostly excurrent and veinlets are constructed in anadromous plan, resulting in narrow areolae along the main vein (rachis). The process of venation formation observed in the juvenile leaves of Lepisorus coincides with that of Lemmaphyllum, Belvisia, Microsorium, Neocheiropteris, and Colysis, all of which are distributed in the Old World, while that of Pleopeltis is similar to that of Phlebodium, Microgramma, and shows common appearance with Polypodium and Goniophlebium in the characters mentioned above.
