Salviani and Harri Lorenzi in the municipality of Três Lagoas in Mato Grosso do Sul.
[4] In 2008 a group of botanists consisting of Larry R. Noblick, Lorenzi, Tsuji and R. Ventura collected the taxon again (Tsuji2674).
[1][5] It was apparently also collected by Kelen Pureza Soares and R. Pimenta in 2012 in the municipality of Água Clara, Mato Grosso do Sul, Brazil, although the georeferenced data provided shows a location in Três Lagoas near the three earlier afore-mentioned collections.
These pinnae are arranged on a single plane on each side of the rachis, such that the pairs form a V-shape down the leaf blade.
[1] Noblick in his 2014 key to the genus Butia also contrasts it to B. capitata, distinguishing the two species from each other by B. matogrossensis having a usually subterranean trunk, a shorter leaf rachis, less pinnae, a smaller swollen portion of the spathe, much less rachillae and the ripe fruit being green or purplish-green as opposed to yellow.
[2] It grows in the same regional vicinity as B. archeri and B. purpurascens in southern Goiás, and B. arenicola and B. campicola in Mato Grosso do Sul, with B. paraguayensis occurring just to the west, south and east of its range.
In 2015 Soares wrote that it had a very restricted distribution in the east of Mato Grosso do Sul in the neighbouring municipalities of Água Clara and Três Lagoas,[1] but as of 2017 more collection localities have been identified.
These include collections in the municipalities of Campo Grande and Terenos by A.C. Marcato in 2001 (at the University of São Paulo herbarium), collections in Campo Grande in 2005 and Inocência in 2008 by Roberto Tsuji (at the Jardim Botânico Plantarum) in the central and north-eastern regions of Mato Grosso do Sul.
[1][5] In 2009 a specimen was collected in the municipality of Caiapônia in south-central Goiás by Renata Corrêa Martins et al. which she herself considered Butia archeri in her 2012 dissertation,[11] but which Eslabão classified as B. matogrossensis in his 2017 thesis.
[13] As of 2018 the Centro Nacional de Conservação da Flora has not yet rated the conservation status for Brazil, and it is listed as 'not evaluated'.
It was grown ex situ in the Jardim Botânico Plantarum in Nova Odessa, São Paulo, Brazil, by 2017.
