Scientists build phylogenies by grouping subsets of species based on which DNA variants they share. Eugene Swart, Deputy Director, Biodiversity Enforcement,with the Department of Environmental Affairs, makes the point that much of the damage to wild populations was done many years ago. Due to superficial similarities in foliage and plant structure, cycads and palms are often mistaken for each other. (Sadly, human habitat destruction and poaching may wipe out what eons of epic devastations could not.). Alas, all are male. Botanist Brian Dorsey came to The Huntington from the University of Michigan as a postdoctoral research fellow to answer some of these questions. Some cycads, such as Macrozamias, however, continue to grow one leaf at a time, with just the interval between leaves getting shorter with age. Lorans garden was very exciting, Folsom says.

The leaves grow in a rosette form, with new foliage emerging from the top and center of the crown. They are also known as the broodboom, or bread tree in Afrikaans, because in times of famine the woody core of the caudex (as the stem or trunk is known) could be boiled, fermented and ground into meal. But a 2011 analysis revealed that while their ancestors coexisted with dinosaurs, the 300 cycad species alive today are much younger. The biggest threat facing cycads is the poaching of plants from the wild to supply domestic and international trade. All travel bookings booked via Trust my Travel are financially protected by them.
