People often confuse cycads as palms due to their similar overall appearance. But they are completely different, and they belong to two separate plant groups. The key difference between cycads and palms is that the cycads are nonflowering plants (gymnosperms) while the palms are flowering plants (angiosperms).

What is the purpose of cycads?

The cycad plants have a long history of use as food and medicine. In traditional Chinese medicine, cycad seeds are used to treat hypertension, musculoskeletal disorders, gastrointestinal distress, cough, and amenorrhea.

Are cycads illegal?

CYCADS AND THE LAW Cycads are listed as Threatened or Protected Species (TOPS) in terms of the National Environmental Management: Biodiversity Act (NEM:BA) of 2004. Permits are required for possession and translocation of all indigenous cycads or cycad material.

Why are cycads toxic?

There are two main toxins in cycads, which are Beta-methylamino-L-alanine (BMAA), a neurotoxic amino acid which causes loss of balance, confusion, and liver damage, and cycasin, which causes gastrointestinal, hepatic, and neurological effects.

Is a cycad the same as a sago palm?

The sago palm may look like a tiny palm tree with its glossy, stiff fronds, but it is not a palm tree at all. Sago palms are cycads, one of the most ancient of plants that has been around since prehistoric times. As a houseplant, it is easy to grow indoors, but be very careful because the sago palm is poisonous.

What makes a plant a cycad?

Cycads are gymnosperms distinguished by crowns of large pinnately compound leaves and by cones typically borne at the ends of the branches. Some cycads have tall unbranched trunks with an armourlike appearance; others have partially buried stems with swollen (tuberous) trunks.

How can you tell the difference between a cycad and a palm tree?

As palms grow, leaves encircle the stem at the base and leave circular scars around the trunk. Alternatively, cycads have two rows of leaves along a stem that uncoil from the trunk. Generally, the trunk of a cycad is stocky, and they also have little or no branching.

How do I identify a cycad plant?

Stems have spirals of relatively smooth diamond-shaped leaf scars. Cycads produce cones. If they have the above characters and a cone, the plant is a cycad.

Can you eat cycad fruit?

The ripe seeds bearing a fleshy, brightly-coloured (orange to red) edible covering, are gathered by foraging marsupials, large birds and even fruit bats, who, after eating the covering, discard the hard seeds and thus distribute them over a wide area.

Is a cycad poisonous to dogs?

JCU is warning dog owners that their pets may suffer severe poisoning if they eat the common household cycad plant. James Cook University is warning dog owners that their pets may suffer severe poisoning if they eat the common household cycad plant.

Article first time published on

Are cycad flowers poisonous?

Cycads contain a toxin called cycasin, which is broken down by bacteria in the gastrointestinal tract to methylazoxymethanol (MAM for short!). MAM is responsible for most of the toxic effects seen in cycad poisonings. Ingestion of any part of the plant can result in poisoning.

Can you eat cycad nuts?

The seeds of cycad plants are a toxic food used by many Aboriginal groups in northern Australia. Acute symptoms produced after consumption of un- treated Cycas seeds are due to azoxyglycosides, especially cycasin, although the toxic dose depends on the animal species tested.

Why do you need a Licence for a cycad?

Because cycads are protected by the national and provincial legislation, as a buyer you must ensure that you know where your plants come from and that you have a permit for owning the plant. Various permits are needed for any activity that relates to cycads such as possession, transport, growing, buying or selling.

What is the most expensive cycad in the world?

Let’s get started. The most expensive cycad in U.A.’s collection, an Encephalartos latifrons, takes about 15 years to seed and is nearly extinct in its native South Africa. Its value: $18,000.

How many species of cycad are there in South Africa?

South Africa has 38 cycad species (one species of Stangeria and 37 species of Encephalartos).

Where do cycads originate from?

The family Cycadaceae is thought to be an early offshoot from other cycads, with fossils from Eocene deposits (54 to 38 million years ago) in Japan, China, and North America, indicating this family originated in Laurasia.

Are sago palms harmful to humans?

Toxicity. Sago palm is known to be poisonous and sago separation includes careful processes to remove these toxins, before they are edible. Intake of sago before proper processing to remove toxins can cause vomiting, liver damage, and even death.

Is Cycas revoluta male or female?

The scientific name is Cycas revoluta, which in Latin identifies the plant as a cycad and describes the revolute nature of the leaflets. Cycads are dioecious, having both male and females. When the sago plants have sexually matured, the female sagos begin to flower producing a basketball-sized structure.

What is the difference between a cycad and an Cycas?

Most Cycas have narrow, smooth-edged leaflets which have a prominent midrib, which allows one to at least tell a Cycas species from any other cycad. 4 species have divided leaves though a few other cycads have similar divided leaves (a few Macrozamias). Most have flat leaflets though some have very keeled leaflets.

Do cycads flower?

Cycads are fascinating. They are ancient cone-bearing plants that co-existed with dinosaurs and covered vast areas of the Earth’s surface 200 million years ago, before flowering plants evolved. … They’re dioecious, which means that male and female cones are born on separate plants.

How fast does a cycad grow?

While cycads have a reputation for slow growth, this is not always the case. Some actually grow quite fast like the Zamia species which reaches reproductive maturity in 2–3 years.

Why is my cycad going brown?

c) Poorly draining soil can cause leaf discoloration including browning to the tips of the leaves, yellow discoloration to the leaves or even leaf collapse. Remember: Cycads die from rot and poor drainage causes rot. Clay soils are notorious for this. If the plant is in a container, change the soil.

How long do cycads live for?

Cycads are incredibly long-lived, with some individuals in the wild estimated to be around 1,000 years old. One of the oldest cycads “in captivity” is in Kew Gardens in London, and it at least 228 years old. Part of the secret of their longevity is that they grow very slowly – producing just a few leaves each year.

Are cycad cones poisonous?

These cones are the part of the plant that has poisonous properties. The seed kernels are highly toxic while the pulp around the seeds is generally considered non-toxic, but could have trace elements of the toxins cycasin and macrozamin. The amount of these toxins will differ from species to species.

Are cycad seeds poisonous?

“The seeds are more toxic than the rest of the plant. However, if your dog eats any part of the plant, he/she will need immediate medical attention.” The clinic said symptoms of poisoning would only show later, after the dog had ingested cycads. “There is little treatment available for cycad poisoning.

Are cycads legal in South Africa?

Trading in cycads is against the law in South Africa. Cycads belong to the species Encephalartos and are on the red list for risk of extinction. In addition to being desired by collectors, the plant is widely used for decorative, medicinal and cultural purposes across Africa.

Are cycads rare?

On the other hand, most cycads are very rare, and two-thirds are officially listed on the IUCN Red List of Threatened Species. A few species are so rare that they are now designated as “extinct in the wild”; this means that they are only known from plants growing in botanic gardens and collections.

When can I transplant a cycad?

Spring and summer are the best times to transplant cycads; this is when their root systems are growing the most rapidly.

Do cycads seed?

Cycads, like pine trees and juniper bushes, are gymnosperms — “naked seed” plants. In other words, they make seeds, but they don’t make flowers or fruit as a way of bringing those seeds into the world or sending them on their way.

Are cycads toxic to cats?

Sago palms are part of the cycad family of plants and are highly toxic to cats and dogs (and people) if eaten.

Can you cut a cycad?

Prune the trunk. If the cycad has become too large, cut off the top and dust the cut portion with benomyl to prevent rot. Offshoots will form along the trunk and in a few months will begin to form a new canopy, or offshoots will appear near the base of the trunk and will replace the overgrown cycad.
