Its natural habitat is restricted to northern Veracruz state in eastern Mexico.·Subterranean stem with above-ground leaves.·Critically Endangered

Zamia vazquezii is a critically endangered cycad species native to a small area in northern Veracruz, Mexico. It is characterized by its subterranean stem and pinnately compound leaves with toothed leaflets. The species is dioecious, producing distinct male and female cones, and its seeds are orange-red to red.

About Zamia vazquezii

Zamia vazquezii is a species of cycad belonging to the Zamiaceae family, notable for its critically endangered status and restricted natural range. This species is endemic to northern Veracruz state in eastern Mexico, where it faces significant threats primarily from habitat loss.

Botanical Description

Zamia vazquezii possesses a subterranean stem that is sub-globular in shape and can reach up to 10 centimeters in diameter. The plant produces between three and thirty compound leaves, each measuring between 0.3 and 1 meter in length. The petiole, or leaf stalk, is 15 to 49 centimeters long and may be either smooth or lightly covered with prickles. The leaf axis supports 12 to 25 leaflets that are ovate to reverse pear-shaped, featuring pointed tips and toothed margins along their outer two-thirds. These leaflets are typically 6 to 7 centimeters long and 3 to 4 centimeters wide at their broadest point.

Like other members of the Zamia genus, Z. vazquezii is dioecious, meaning individual plants are either male or female. The male reproductive structures, known as strobili or cones, are ovoid to ovoid-cylindrical, measuring 5 to 7 centimeters long and 2 to 2.5 centimeters in diameter, and are tan in color. They are borne on peduncles (stalks) that are 1.5 to 2.5 centimeters long. The female cones are larger, cylindrical to ovoid-cylindrical, and range from 10 to 15 centimeters in length and 5 to 7 centimeters in diameter, with colors varying from tan to brown. The seeds of Zamia vazquezii are a striking orange-red to red, measuring 1.3 to 1.8 centimeters long and 0.5 to 0.8 centimeters in diameter.

Conservation Status and Distribution

Zamia vazquezii is critically endangered, with only two known wild populations containing a combined total of fewer than 50 individuals. This precarious situation underscores the urgent need for conservation efforts to protect this unique species and its limited habitat in Veracruz, Mexico.

What is the conservation status of Zamia vazquezii?

Zamia vazquezii is classified as Critically Endangered. This designation reflects the severe threats to its survival in its natural habitat.

How many individuals of Zamia vazquezii are there in the wild?

There are very few individuals remaining in the wild, with only two documented populations. The combined total number of individuals is estimated to be no more than 50.

What are the key distinguishing features of Zamia vazquezii's leaves?

The leaves are compound, typically between 0.3 and 1 meter in length, with a petiole that can be smooth or lightly prickled. Each leaf axis bears 12 to 25 leaflets that are ovate to reverse pear-shaped, pointed, and toothed along the outer two-thirds of their margins.

What do the cones of Zamia vazquezii look like?

Zamia vazquezii is dioecious, meaning it has separate male and female plants. Male cones (strobili) are ovoid to cylindrical and tan, measuring 5-7 cm long, while female cones are cylindrical to ovoid-cylindrical, tan to brown, and larger, measuring 10-15 cm long.

What is the origin of the specific name 'vazquezii'?

The specific epithet 'vazquezii' honors Mario Vázques Torres, who was the first person to collect this plant.
