Abstract:
A new subtribe of the family Urticaceae, Sphaerotylinae C. J. Chen, a new
genus, Sphaerotylos C. J. Chen and its type species S. medogensis C. J. Chen from
south-eastern Xizang (Tibet) in China are described and illustrated. The subtribe is
regarded as a primitive group in the tribe Boehmerieae. The ring-shaped stigma and
the ball-like connective are the first discovery in the family Urticaceae. The types of the
stigma of the family, their taxonomic significance and their evolution are also discussed
in the present paper.
