The mature foliage looks very similar between both groups, but the young emerging leaves of a cycad resemble a fiddlehead fern before they unfold and take their place in the rosette, while the leaves of palms are just small versions of the mature frond.
The Zamiaceae are a family of cycads that are superficially palm or fern-like. They are divided into two subfamilies with eight genera and about 150 species in the tropical and subtropical regions of Africa, Australia and North and South America.
The sperm of members from the genus are large, as is typical of cycads, and Z. roezlii is an example; its sperm are approximately 0.4 mm long and can be seen by the unaided eye. [11] It was long believed that Zamia plants, like all cycads, relied completely on wind pollination.
Cycas is a genus of cycad, and the only genus in the family Cycadaceae with all other genera of cycad being divided between the Stangeriaceae and Zamiaceae families. Cycas circinalis , a species endemic to India, was the first cycad species to be described in western literature, and is the type species of the genus.
Like other cycads, Z. integrifolia is dioecious, having male or female plants. The male cones are cylindrical, growing to 5–16 cm long; they are often clustered. The female cones are elongate-ovoid and grow to 5–19 cm long and 4–6 cm in diameter. [8] It produces reddish seed cones with a distinct acuminate tip.
While there are more than 200 species of cycads, only one is native to Florida, and only a couple are popular landscaping plants in our area.
In Cambodia, where the fern is known as prâng' tük (prâng'="cycad", tük="aquatic", Khmer language), the young leaves are eaten in salads. [3] In the Indian state of Goa the fern is consumed cooked in a spicy coconut based gravy known as tonak. It is considered a delicacy by the local people.
Stangeria eriopus is a very long-lived, perennial, evergreen cycad. The stalked, feathered, fern-like leaves are between 25 centimeters and two meters long, with the petiole comprising one third to one half of the overall length (in both varieties). They are pinnately-veined, which distinguishes the species from all other cycads.
