  • Wendland (1854) described and named C. klotzschiana from material growing at Herrenhausen. It is apparently restricted to the state ofVeracruz in Mexico. C. klotzschiana is one ofthe most distinct members of the genus and is easily recognizable by its lanceolate pinnae clustered in groups of 2-4 along the rachis. C. glaucifolia also has its leaflets clustered in groups along the rachis but the more numerous (40-80 on each side), narrowly linear pinnae in several planes distinguish it from C. klotzschiana.
    Because of its attractive foliage, C. klotzschiana is widely cultivated and much sought after by collectors. It is found in gardens and collections in California, Florida, Hawaii, and Australia.
