C. sphaerica is a data deficient red-listed species. It is a tropical dry deciduous dioecious shrub confined to northern Eastern Ghats of India. It reproduces asexually and sexually. Both the species are anemophilous. The restricted participation of plants in annual coning event, restricted seed dispersal, seed infestation and other factors relating to natural regeneration contribute to the endemic and endangered status of the plants.
