Morphology and ITS sequences provide insights into the phylogeny of Tongoloa (Apiaceae) from China.

ABSTRACT:

Background

Tongoloa is a genus comprising approximately 20 species, primarily distributed in the mountainous regions of southwest China. The insufficiency of specimen materials and morphological similarities among species render it a taxonomically challenging genus within the Apiaceae family. To elucidate the phylogenetic relationships and taxonomy of Chinese Tongoloa, this study utilized a total of 115 nrITS sequences, including 47 recently obtained sequences, for phylogenetic reconstruction.

Results

Phylogenetic relationships reconstructed from ITS sequences indicate that the East Asia Clade and the Komarovia Clade are sister groups, and Tongoloa belongs to the East Asia Clade. Species of Tongoloa are subdivided into 3 distinct groups, all sharing similar fruit morphologie
