摘要:
SUMMARY1The seedling ofTilia vulgarispossesses two typically five‐lobed epigeal cotyledons.2The cotyledonary lobes vary in size and may show elongation or shortening compared with a common mean type. They may also develop accessory lobes.3The aerial parts are thinly pubescent, the hairs present being of two types:–(a) Unicellular ones confined to the epidermal ridges above and below the veins of the cotyledon laminæ but generally distributed over the hypocotyl. (b) Club‐shaped multicellular hairs confined to the upper surfaces of the cotyledons between the veins.4The vascular system is tetrarch in plan and typical root‐structure is only attained some distance below the collet.5Seedlings showing triarchy or pentarchy also occur.6Syncotylous seedlings, where the syncotyly is unilateral and at all pronounced, show triarch symmetry.7The polycotylous seedlings examined are pentarch, though the pentarchy occurring in this case is not homologons with that occurring in
