Hello, I'm glad to answer your question. Its internal anatomical features are similar to those of other dicotyledonous plants. Look at those. I will give some external morphological features: erect or creeping herbs or shrubs with double tough vascular bundles. Single leaf entire, divided or pinnately compound, alternate, without stipules. Flowers bisexual, actinomorphic, sparsely bilaterally symmetrical, solitary or cymes. Calyx and corolla are divided into five parts, arranged in tweezers, radial, and alternate with the same number of stamens and corolla lobes. Anthers 2-loculed, longitudinally dehiscent or perforated, 3-sulcate. Use a disk. Ovary 2-loculed (sparsely 3-5-loculed), with placentation in the axial direction and many ovules. The fruit is a berry or capsule. In addition, through transpiration, the blue water is absorbed by the root and enters the petiole through the catheter. The cross section of the catheter is concentric and there is a blue spot in the middle, which is the catheter part. A small blue ditch-like structure can be seen vertically.
