Abstract

Hortoniaの材及び樹皮の解剖学的特徴が記述された。材の特徴は成長輸を持たない散乱材で, 道管要素は細長い。道管相互壁孔は移行型, 繊維状仮道管は隔壁を持たず有縁壁孔がある。軸方向柔細胞は独立散在柔組織, 放射組織は異性型であり結晶をもつ。油細胞はない。樹皮には樹皮繊維があり, 放射組織は拡張しないし軍後に厚壁化する。Hortoniaに見られる道管や木部繊維の特徴は一般に原始的とみなされるが, これらの特徴はモニミア科の他の属にも観察される。したがって, これまでたびたび繰り返されたきたことと違って, Hortoniaがモニミア科の中で原始的な材構造を示す唯一の属ではない。

Wood and bark anatomy of Hortonia, which is generally considered the most primitive genus in Monimiaceae, was investigated to reconfirm early information and to fill up a gap in our knowledge. Remarkable features include : vessel elements very long and narrow with exclusively scalariform perforation plates ; intervascular pittings in transitional state ; fiber-tracheids non-septate and non-stratified with bordered pits ; axial parenchyma apotracheal ; rays heterogeneous and multiseriate ; phloem fibers present ; phloem rays not dilated. Comparisons with other genera suggest that Hortonia is not the only genus retaining primitive wood anatomical features in the family.
