The following points highlight the five major reasons of anomalous secondary growth in plants. The reasons are: 1. The Activity of Normal Cambium is Abnormal 2. Abnormally Situated Cambium Forms Normal Secondary Vascular Tissues 3. Formation of Secondary Tissues by Accessory Cambium 4. Formation of Interxylary Phloem 5. Formation of Intra-Xylary Phloem. Reason # 1. The Activity of Normal Cambium [...]
