Trithrinax campestris
''Trithrinax campestris'' or ''caranday palm'' is a South American arecaceae palm native of Uruguayan and northeastern Argentine sabanas, where it shares its habitat with ''Copernicia alba'' 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 flowering palm of relative low height (up to 6 m tall) and 20–25 cm wide stems usually covered by remains of earlier foliage that act as a thick protective coat. Caranday leaves are about 1 m long, palmate, rounded, with a very rigid and spiny petiole.
The leaflet segments are rigid, dark green to a more blue hue, with light green undersides. These are possibly the toughest leaves among arecaceae. As habitat altitude increases the foliage becomes more grayish, this is typical of mountain carandays. Flowers compose highly branched inflorescences located at the base of the lower living leaves. These contain up to 100 white hermaphrodite flowers 10 to 12 mm wide. This palm flowers in autumn. Fruits ripen towards the end of the next summer. They consist of subspherical yellow brownish drupes, 1 to 2 cm wide, with a thin fleshy mesocarp and a fibrous endocarp. Caranday is monoecious, a feature common to the conifers but rare in angiosperms.〔Molnar, Sebastian. 2004. ( Plant Reproductive Systems ), internet version posted February 17, 2004〕
