among others and extends also to the summits of mountain ranges of Sierras de Córdoba and Sierras de San Luis. It is a very rustic palm that grows in arid, well drained, rocky soils. Its distinctive features are its compact shape, short green to grayish foliage, and trunk fully hidden by dry dead branches (coat) remaining from several previous seasons.

Morphology

Trithrinax campestris is a monocot

Petiole (botany)
In botany, the petiole is the stalk attaching the leaf blade to the stem. The petiole usually has the same internal structure as the stem. Outgrowths appearing on each side of the petiole are called stipules. Leaves lacking a petiole are called sessile, or clasping when they partly surround the...

, a feature common to the conifers but rare in angiosperms.

Habitat

Trithrinax campestris prefers well drained, sandy or rocky soils (although it is ignorant to extended persistent flooding). It is very resistant to drought, and -9°C/-15°C temperatures when not in growing season; else leaves are promptly discarded. It is one of the most cold-hardy palms
Hardy palms

. Seeds germinate quickly but later growth is mostly slow.

This palms are naturally found in groups, formations of several individuals or composing largue caranday forests where they present strong dominance. Its main environmental threat is deforestation or natural fire, caranday thick dry stem coats are highly flammable.

Usage

Leaves are rich in strong fiber, very resistant to tension. It is extracted to manufacture crafts as hats, shoes and fans. Whole leaves are cut and used as rudimentary brushes. Fruits are not eaten, however, an alcoholic beverage is prepared locally through their fermentation

Caranday palms are also appreciated and grown worldwide as an easy to keep, cold weather and drought resistant, ornamental small palm.
It is besides a good honey-producing plant
