夏威夷大戟的分离叶脉

在夏威夷大戟属的几种植物的叶肉中存在孤立的脉节。这些异常结构似乎完全由管胞组成，是一个正常的特征解剖的物种原产于中温带和潮湿地区，但不是干旱，干燥的栖息地。
Isolated segments of veins occur in the leaf mesophyll of several Hawaiian species of Euphorbia. These anomalous structures appear to consist entirely of tracheids and are a normal feature of the anatomy of species native to mesic and wet areas, but not to xeric, dry habitats.
