Butia catarinensis
Butia catarinensis is a mid-sized species of Butia palm native to the states of Rio Grande do Sul, Santa Catarina in Brazil.
Etymology
The specific epithet refers to the Brazilian state of Santa Catarina where it is the most distributed.Taxonomy & nomenclature
These palms were only named as a new species in 2010, although the populations of this species were known. Before 2010 the palms growing in this region were classified as Butia capitata.J. R. Mattos reclassified this population as B. capitata var. odorata in 1977,
As such, a number of palms under cultivation in botanical gardens, private collections or in the nursery trade under the name B. capitata or B. capitata var. odorata are in fact this species.
Larry R. Noblick and Harri Lorenzi described B. catarinensis, B. matogrossensis and B. pubispatha in 2010 in the Flora brasileira: Arecaceae by Lorenzi et al..
Description
This is a solitary-trunked palm, the trunk being, exceptionally, tall, with a diameter of. The trunk is covered with the persistent bases of the old palm fronds. These fronds are 9–32 in number and arranged in a spiral around the trunk. The blade is by. The petiole is glabrous, in length and wide, flat on top and round elsewhere. The margins of the petioles are densely toothed with numerous, robust, up to long spines, and many flattened fibres when the leaves are young. The rachis of the leaf is in length, with 48-62 pairs of pinnae which are glaucous-coloured and arranged uniformly along the rachis. Unlike other species of Butia, these are usually in the same plane, but sometimes inserted at very slightly divergent angels along the rachis, but without giving the leaf a plumose aspect such as in Syagrus, and with each pair of pinnae forming a neat V-shape. The pinnae in the middle of the leaf blade are long and in width.The inflorescence is branched to the 1st degree, has a peduncle long and wide, and has a prophyll long, wide, and covered in a brown tomentum. The young inflorescence develops in a glabrous, lightly striated, woody spathe which is in length and has an enlarged portion at the end which is long wide and ending in a short, sharply pointed tip. The axis of the inflorescence is long. The rachis of the inflorescence is long and has 35-135 rachillae which are long. The flowers can be coloured yellow, greenish-yellow, yellow and violet, or completely violet. The staminate flowers are in length; the pistillate flowers are.
The shapes of both the fruit and nut are ovoid. The ripe fruit are coloured yellow, orange, or red. The fruit are long, wide, have a persistent perianth, and have a yellow, juicy, lightly fibrous flesh. The nut is hard, long, wide, dark-brown coloured, contains a homogeneous endosperm, and has 1 to 2, rarely 3, seeds within. The nut is without a beak or other sort protuberance on its apex.
