本文通过光学显微镜和扫描电子显微镜对麦冬属、鹅掌楸属和Peliosanthesis属植物的营养解剖（特别是叶）进行了描述。一个综合征的叶特征，包括表皮特征;下皮纤维状细胞;针晶和不寻常的短，方端棱柱晶体排列在板;韧皮部丰富的厚壁组织和频繁的单个股，每个组成的筛管分子和其相关的同伴细胞;和维管束与不寻常的方向，这表明非常密切的相互关系opennegonandliriope。厚皮花属与厚皮花属具有相同的韧皮部类型、下皮纤维状细胞和针晶，但在表皮特征和维管束定向方面不太相似。不寻常的韧皮部类型的意义被认为是在百合科的其他成员类似的类型。
The vegetative anatomy (particularly leaf) of species ofOphiopogon, LiriopeandPeliosanthesis described from observations with light and scanning electron microscopy. A syndrome of leaf characters is present, including epidermal features; hypodermal fibre-like cells; raphides and unusual short, square-ended prismatic crystals arranged in plates; phloem with abundant sclerenchyma and frequent individual strands each composed of a sieve tube element and its associated companion cell; and vascular bundles with unusual orientation, which shows the very close inter-relationship betweenOphiopogonandLiriope. Peliosanthesshares the phloem type, hypodermal fibre-like cells and raphides, but is less similar in epidermal characters and vascular bundle orientation. The significance of the unusual phloem type is considered in relation to similar types in other members of the Liliiflorae.
