- Comments
- Leaves of our plant exhibit certain superficial resemblance with leaves observed in some gesneriads (like species of Boea Lam., Calcareoboea H.W. Li, Paraboea Ridl., etc.). The name of new species reflects this similarity unusual among Begonias. Obviously related species B. gesnerifolia and B. minuscula have some superficial resemblance with miniature Chinese begonias having almost round, symmetric leaves, such as – B. zhengyiana Y.M. Shui (Sect. Coelocentrum), B. gulinqingensis S.H. Huang et Y.M. Shui, B. mashanica D. Fang et D.H. Qin and B. suboblata D. Fang et D.H. Qin (Sect. Diploclinium). Meanwhile, rigid, symmetric, reniform, crenate or crenulate leaves (always distinctly broader than long), scurfy hairy along veins on abaxial surface indicate certainly isolated taxonomical position of our plants described here. We see no close relatives of these both species among their Indochinese congeners.
