Espinhaço山脉是从米纳斯吉拉斯的欧罗普雷托市延伸到巴西东部巴伊亚的查帕达迪亚曼蒂纳地区的山脉。利希尼奥-德阿尔梅达的塞拉杰拉尔（SGLA）位于巴伊亚西南部的埃斯皮尼亚索七区，其生物多样性仍然知之甚少。为了有助于更好地了解SGLA的植物区系多样性和植被，我们编制了一份清单，其显花植物和特点的植物，不同的植物形成的外貌。共记录到97科410属811种。根据植物区系组成和生态学参数，将其划分为5个群系：（1）落叶林，（2）半落叶林，（3）“Cerrado”s.str.，(4)岩石领域（“坎波斯Rupestres”），和（5）岩石卡廷加（“卡廷加Rupestre”）。我们的研究结果表明，SGLA是“塞拉多”和“卡廷加”域之间的过渡区，并构成了一个生态走廊，连接北方和南部的埃斯皮尼亚索山脉的支持下，记录为巴伊亚州的24个新的发生。
The Espinhaço range is a mountain chain that extends from the municipality of Ouro Preto in Minas Gerais to the Chapada Diamantina region in Bahia, eastern Brazil. The Serra Geral of Licínio de Almeida (SGLA) is located in the Espinhaço Septentrional in southwestern Bahia, and its biodiversity is still poorly known. In order to contribute to a better understanding of floristic diversity and the vegetation of SGLA, we have compiled a checklist of its flowering plants and characterized the phyto-physiognomy of the different plant formations. A total of 811 species in 410 genera and 97 families are recorded in our study. Based on floristic composition and ecological parameters, we recognize five plant formations as follows: (1) deciduous forest, (2) semi-deciduous forest, (3) “Cerrado” s.str., (4) rocky fields (“Campos Rupestres”), and (5) rocky Caatinga (“Caatinga Rupestre”). Our results indicate that the SGLA is a transitional area between the “Cerrado” and “Caatinga” domains and constitutes an ecological corridor that links the northern and southern portions of the Espinhaço Range supported by 24 new occurrences recorded for the state of Bahia.
