Notes
Close to C. tribuloides, C. echidnocarpa and C. ferox from India and Burma, C. brevi-spina and C. chinensis from Formosa and China, and C. cuspidata from Japan; it differs mainly in the cupule which is covered with short tubercles and not with spines, and to some extent also in the pubescence on the lower surface of the leaves. From its nearest ally in Malesia, C. buruana, it may be distinguished by its smaller leaves with incised margin in the apical half, and by its smaller cupule with shorter tubercles.
In several specimens the trunk was recorded to produce many coppices round the base.
