Resumo
Mussununga is an understudied ecosystem within the Atlantic Forest domain, in sandy spodosol
lowlands from Bahia to Espírito Santo. Its physiognomy varies from grassland to forest, with a
transitional savannic area. We evaluated the life-form spectra differences between the grassland
and savanna Mussunungas and its relationship with the depth of a soil impermeable layer (ortstein).
The study area is located in the municipality of Linhares, Espírito Santo State. Ten plots were
settled in each physiognomy. The floristic and vegetation spectra (accordingly to Raunkiaer) were
compared using the G-test. A total of 35 species into three life-forms were found: Phanerophytes,
hemicryptophytes and cryptophytes. The floristic spectra were similar in both physiognomies,
with a greater richness of phanerophytes. However, the vegetation spectra of the two areas
were different. Phanerophytes dominated in the savannas (where ortstein is deeper), while the
shallower ortstein of the grasslands favored hemicryptophytes.
