Endocarpic trichomes have been analyzed in fruits of 267 species from 80 genera of the orchid tribe Vandeae, using light and scanning electron microscopy. They have been observed for the first time in 56 genera and confirmed in the rest. The present study describes their microstructure in Vandeae and suggests a standardization for its terminology. Endocarpic trichomes are unicellular, thin, tightly cylindrical, hollow, with an obtuse apex and an expanded foot. The outer surface shows a helicoidal micro-ornamentation, usually covered by waxes. Perforations of the walls have been mainly observed at the outer surface in the foot, and the basal and apical regions. The inner wall is formed by helicoidal thickenings which are responsible for the movement of the endocarpic trichomes. These are present in all the species studied of Vandeae, irrespectively of the life form.

使用光学和扫描电子显微镜对兰部落凡德科80属的267种果实的内果毛进行了分析。他们在56属中首次被观察到，其余的则被证实。本研究描述了它们在Vandeae中的微观结构，并提出了其术语的标准化方法。内果皮的毛状体是单细胞的，薄的，紧密圆柱形的，空心的，具有钝的先端和扩张的足。外表面显示出螺旋状的微装饰，通常被蜡覆盖。壁的穿孔主要在脚的外表面以及基底和根尖区域观察到。内壁由螺旋状增厚形成，该增厚负责内果皮毛状体的运动。这些存在于凡迪亚研究的所有物种中，
