Description

Acaulescent, or sometimes with a short trunk up to almost I m high; sheathing leaf base 13-15 cm long; petiole 8-9 cm long and I cm wide, margins not spiny, merely fibrous; rachis of leaf 66-72 cm long; pinnae 28-44 on each side, regularly arranged, middle ones 36-40 cm long, 0.8-1.3 cm wide, mostly with acuminate, asymmetrical tips; expanded part of spathe 30-39 cm long, 3 cm wide, smooth or striate, glaucous, peduncular part 30 cm long; branched part of spadix 20-30 cm long, rachillae 15-31, each 10-19 cm long, peduncular part of spadix 36 cm long; pistillate flowers rounded or ovoid, 4-7 mm long, 4-6 mm in diam., sepals and petals with obtuse tips; staminate flowers 5-7 mm long on lower part of rachilla, 3-5 mm long on upper part; mature fruit 1.82.0 cm long, 1.0-1.4 cm in diam., short. beaked, persistent perianth 8-10 mm high, endocarp woody, 1-1.5 mm thick, locules 1-2; seed (when single) irregularly globose, 7-9 mm long and 7-9 mm in diam., or when two are present flattened laterally, 10 mm long, 6 mm in diam. (S.F. Glassman. 1979)/Palmweb. Editing by edric.

This taxon can be easily distinguished from other acaulescent species of Butia (e.g., B. arenicola and B. paraguayensis) by its smooth rather than dentate petiole margins; and from B. microspadix by the more or less glabrous rather than densely tomentose spathes. (S.F. Glassman. 1979)/Palmweb.

Comments and Curiosities

A very rare and beautiful small palm from Goias, Minas Gerais, Sao Paulo, Southern Brazil, where it grows in Cerrado vegetation in open grasslands. The trunks rarely reach 1m tall, the palms having distinctive arching leaves. The palm is almost unknown in cultivation. This palm is new to cultivation, so its hardiness is unknown, but is likely to show considerable cold resistance like the remainder of its genus. It is almost extinct in habitat. (butia.nl).
