壳斗

Leaf secondary veins 10-16 on each side of midvein; bracts not fused to cupule.

叶次脉10-16在中脉两边各；苞片不熔化成壳斗。

Cupule bracts triangular, narrowly triangular, or ovate-lanceolate, adherent to outside wall of cupule.

Cupule苞片三角形，狭三角形，披针形或卵形，对在壳斗的墙外边粘性。

Ca. 10 mm, covering base of nut; cupule bracts ovate-lanceolate, ca.

约10毫米，包括坚果的基部；壳斗苞片卵状披针形，约1毫米，淡灰棕色被绒毛 18 Q。

Cupule bracts scalelike, triangular, ovate, or elliptic, adherent to outside wall of cupule.

鳞片状，三角形，卵形的Cupule 苞，或椭圆形，对在壳斗的墙外边来说粘性。

Leaf blades of current year pubescent or rusty scurfy; wall of cupule 2-4 mm thick

当年短柔毛或锈色的的叶片具鳞屑；壳斗2-4毫米厚的壁 31 Lithocarpus laetus 屏边柯

Cupule bracts triangular, inconspicuous, fused with cupule and often apically in 2-4 rings.

Cupule苞片三角形，不显眼，用壳斗和经常在2-4个圈顶部熔化。

Cladistic analysis of morphologic characters A neighbor-joining tree of 71 Fagaceae species based on 75 leaf cuticle, architecture, fruit and cupule characters was constructed.

在总结前人对壳斗科叶结构和叶表皮研究和本研究结果基础上列出了属的检索表和70种的检索表。

Genetic diversities were evaluated and compared at three levels of morphology(i.e., apical bud, leaf, seed and cupule for nine populations), allozyme and DNAs(AFLP analysis on four populations) in order to determine core germplasm of Q.

测定了共计9个群体的当年生枝的顶芽、叶、坚果、壳斗的表型多样性、9个群体的等位酶多样性、其中4个群体的DNA多样性，并对3个不同层次的遗传多样性研究进行了比较和评价。

Cupule bracts triangular but subulate from middle to apex of cupule, conspicuous, obliquely spreading.

但是从中间在壳斗的顶钻形，显眼的Cupule苞片三角形，斜开展。

Based on field collection, observation, Ethnobotany survey, herbarium specimens and literature checking, authors recorded the current utility status of Fagaceae plant resources (the abundance, distribution and the utility) in Guangxi Zhuangzu Autonomous Region of Southwest China.

摘要在较全面野外考察、调研的基础上，结合资料查询、查阅，对广西壳斗科植物的发掘和利用进行了初步探索研究。

The split between the two groups can hardly be papered over.
