CR (Critically Endangered) B2a, c(iv); C2b.
The species is only known from the Município Novo Mundo, Mato Grosso State, Brazil. Endemic to Brazil (Mato Grosso); c. 270 m.
The plants are locally common in dense shade in what has been called floresta ombrófila densa submontana (Sasaki et al. 2010), or floresta ombrófila alta (Zappi et al. 1242).

Morphology Stem
Stems simple, erect, fleshy, green, pilose, hairs multicellular, uniseriate, eglandular, apices acute
The species is named after Gracieli da Silva Henicka, one of the co-collectors of the type collection and who went back to the type locality to secure flowering material and take additional images of the flowering plants.
