Cinnamomum cassia variety group:
This variety is bushy, with low tree shape, short and dense branches and spherical crown. The new leaves are deep red, and the old leaves are green or yellow-green; The leaves are elliptic, broadly ovate, whole or sparsely serrated, and the undulation of the leaf margin is not obvious; The leaves are thin, the mesophyll on the leaves is slightly convex, and the reticular veins are obvious. The average length of petiole is about 65438 0 cm. The important feature is that the intersection angle between the main vein and the lateral vein of the leaf is very large, which is close to the vertical state.
