description

Agave fourcroydes grows with thick stems and forms rosettes with runners . The rigid, straight leaves are linear and runny. They are rounded at the base and taper to a point. The leaves are 120 to 180 inches long and 8 to 12 inches wide. On the straight edge of the leaf there are dark brown, 3 to 6 millimeters long, slender marginal teeth at regular intervals. The strong, dark brown, conical end spine is short and openly furrowed at the top and usually 2 to 3 centimeters long.

The 5 to 6 meter high inflorescence is paniculate and transmits in the upper half 10 to 18 part inflorescences and bulbils . The individual flowers are 6 to 7 inches long. Their tepals are greenish yellow. They have almost identical tips 16 to 18 millimeters in length. The urn-shaped flower tube is 12 to 16 millimeters long.

Seeds are never formed.

The number of chromosomes is 2n = 50 or 150.

Systematics and distribution

Agave fourcroydes is only known to be cultivated and is mainly found in eastern Mexico .

The first description by Charles Lemaire was published in 1864. Synonyms are Agave ixtlioides Lemaire ex Jacobi and Agave sullivanii Trelease .

use

The leaves of Agave fourcroydes are soft fibers that can be spun, which are known as "henequen". With an average length of 2.88 millimeters for an agave fiber, the individual cells are extremely long and 22.6 micrometers thick. Nevertheless, they cannot be spun (minimum length required: 25 millimeters), so fiber bundles are processed.
