Macrophyll - Taiyo (English)

In plant morphology, megaphyll generally refers to the leaves of vascular plants other than the club mosses (one of the four taxonomic groups of ferns). Unlike leaflets, when megaphyll occurs on a stem, a gap called a slit is always formed in the vascular bundle of the stem. In ecology, megaphyll is one of the "leaf shape classes" of Roenkel, which classifies life forms (shapes), and refers to leaves with a leaf area of ​​18,225 to 164,025 square millimeters. Leaves larger than this are distinguished by the term megaphyll.

Japanese:

植物形態学上の用語として用いられる大葉は、普通ヒカゲノカズラ類(シダ植物の四つの分類群の一つ)以外の維管束植物の葉を意味している。小葉と違って、大葉が茎に生じる場合は、かならず茎の維管束に葉隙(ようげき)とよばれるすきまが形成される。生態学上の用語として用いられる大葉は生活型(形)を分類したラウンケルの「葉形クラス」の一つで、葉面積が1万8225~16万4025平方ミリメートルの葉である。なお、これより大形の葉は巨大葉megaphyllとよんで区別される。
