Butia
Butia Becc. (1916), is one of Palmier S of Arecaceae. Its scientific name is derived from the one of names that one gives him in South America.
Taxonomy
It divides its subgroup with eight other kinds of which the kinds Cocos and Jubaea. It is very close to the kind Syagrus.
Description
-
Butia are pennate palm trees with Feuille S, equipped with a bluish crown which is made up of arched sheets. They are laid out irregularly along the median coast, leaving partially by two or three.
- Them feather-grass is robust, color gray, and covered by foliar bases very coriaces. The feather-grass remains a long time wrapped in the foliar bases of the faded sheets, which mark them ringed scars.
- the Fruit S of unquestionable Butia are edible. The pulp of the fruits of Butia capitata can thus be consumed raw, in frost, or macerated in alcohol.
Habitat
The Butia kind has a habitat located enough. It is typical South American Pampa. One finds the nine species in the east of the Paraguay, in the south of the Brésil, the north of the Uruguay, and in the North-East of the Argentine. Some of the species are threatened today of extinction because the grassy zones on which they push are intended for the intensive agriculture and are transformed into cereal fields.
The kind includes/understands cold rather resistant species. Certain species resist temperatures from -10 to -12 °C. It rather is thus frequently planted apart from its natural habitat, in particular in the gardens of Europe. One thus finds two specimens in the botanical garden of La Rochelle.
Cold resistance of some species of the Butia kind
The figures are given as an indication. They give cold maximum resistance under good conditions: short cold and dry air, adult plant.
