Abstract
Potentilla gobica is described as a species new to
science from the summit region of the Baytik Shan massif in the SW
Mongolian-Chinese borderland. It is characterized by digitate leaves
and an entirely glabrous surface, except for small ± sessile
glands, of all plant parts. Only one other species entirely lacking
eglandular hairs was so far known worldwide, the E Siberian and
Mongolian P. sanguisorba, which has, in contrast,
pinnate leaves.
Key words: cinquefoil, taxonomy, Mongolian-Chinese borderland,
Baytik Shan massif.
