Latest Cycad Stories
Molecular clocks -- based on changes in genetic material -- indicate much younger ages for a wide variety of plants found as fossils in southern Argentina than do the solid, geologic dates of those fossils

Modern cycads have large, heavy seeds with a fleshy outer coat, suggesting they rely on large bodied fruit-eating animals to disperse their seeds. However, little evidence has been found that modern larger-bodied animals like emus or elephants are eating and dispersing the seeds.
Everyone needs to eat. But it's a dog-eat-dog world, and with the exception of the top predators, everyone also gets eaten. To cope with this vicious reality, a tiny insect that eats plants has learned to employ the plant's hairs for physical protection from its beetle predator.
The beautiful, endemic and endangered cycad, Cycas micronesica was once a dominant forest tree on the island of Guam, but recent plant mortality predicts extirpation from Guam habitats by 2019.
The palms that Vietnamese villagers weave into hats, many varieties of lichens that depend on the pristine environment of the Great Smoky Mountains, and small, shrub-like trees that are threatened by development and deforestation in Brazil were among the scores of plant and fungus species that scientists at The New York Botanical Garden discovered and described in the course of one year.
New research published this week in the Proceedings of the National Academy of Sciences provides new insights into flowering plants' genetic origins, an evolutionary innovation that quickly gave rise to many diverse flowering plants more than 130 million years ago.
Cycads, "living fossil" descendents of the first plants that colonized land and reproduced with seeds, are rapidly going extinct because of invasive pests and habitat loss, especially those species endemic to islands.
"The small size of an alien insect that feeds on a native tree from the western Pacific island of Guam allows it to hide in cracks and other locations that are out of reach for its only local natural enemy," said UOG entomologist Aubrey Moore.
Moth also triggers the plants into increased frequency of reproduction.
Macrozamia communis is a type of Australian cycad plant. The species is located on the coast of New South Wales. It is commonly known as the Burrawang. Its common name is derived from the Daruk Australian Aboriginal Language. This name is often applied to other species of Macrozamia. M. communis normally has an un-branched trunk, cycad plants branch very rarely. The species has dark green colored leaves which become dull with age. This plant has separate male and female specimens that are...
Encephalartos woodii is a palm-like cycad plant species. The species is commonly known as Wood's cycad. This particular species is one of the rarest in the world. It is fully extinct in the wild. Any plants of this species growing today are only clones. E. woodii can grow up to heights of 20 feet tall. Its trunk measures from 12 to 20 inches in diameter. It thickens at the bottom and is topped by a cap of 50 to 150 dark green glossy leaves. The leaves are about 60 to 100 inches long with...
Encephalartos villosus is a South African cycad, or Palm-like plant. Commonly named, poor man's cycad. The species is a member of the Zamiaceae family. It’s a common cycad between the East London vicinity and the northern border of Swaziland. The plants can be found growing several hundred miles inland. Very little of the plant is visible. E. villosus has a largely underground trunk. This has led it to be improperly categorized as a dwarf species. The crown of the plant is made up of...
Encephalartos transvenosus is a palm-like cycad species plant. The species is also referred to as the Modjadji Cycad. It belongs to the Zamiaceae family. The plant is described as a tall and majestic tree. The species’ name, transvenosus, references the plant’s tiny network of veins found in between the plant’s main veins. They become visible when its leaf is held up under a light. E. transvenosus can grow up to 38 feet tall. Its trunk is thick and covered in a netted pattern. Its...
Encephalartos longifolius is a palm-like cycad species plant. The plant belongs to the Zamiaceae family. The species may also be referred to as the Broodbroom or Breadpalm. The species scientific name comes from Latin origins: longis (long), and folius (leaf). E. longifolius can grow up to 10 feet tall. With age, it develops an extremely thick trunk. The cycad is crowned with metallic or dark green semi-gloss leaves. Its leaves can grow up to 7 feet long. The plant’s leaflets overlap...
