About: Using cones to identify the indigenous Cycads of South Africa

Cornia Hugo's passion for cycads led to the publication of her first book "Identification of indigenous cycads of South Africa". The guide became hugely popular in the Cycad community of South Africa and has prompted the author to present training courses on Cycad identification to members of the public, the South African Police Services as well as to Provincial and National Nature Conservation officials. In working with cycad enthusiasts it became clear that the additional use of cones to identify cycads assisted with improving the correct identification. Plants growing in unnatural conditions would also on occasion present different typical characteristics, which made accurate identification difficult. If a cycad is not planted in its natural growing habitat the appearance of the leaf will present different characteristics as the norm. Even when using the key, the identification of seedlings still proved to be problematical in some of the species. Climate will have an influence on the pollination of female cones, and on the pollen shedding of male cones. Cornia Hugo believes that using the cones when present will overcome these difficulties regarding identification.
