Tunguahara • Valley of the Pastaza River , between Baños and Cashurco , 8 hours east of Baños ; 1300–1800 m a.s.l. ; 25 Sep. 1923 ; A.S. Hitchcock 21889 ; syntype : US [ US00221970 ]). – PERU • Lobb s.n .; syntype : W [n.v.]. Brako & Zarucchi (1993: 195) . Notes Brako & Zarucchi (1993) included B. tetrandra Irmsch. in the latest checklist of Peruvian Begonia based upon Lobb s.n. (W), a syntype of the name. We have not seen this specimen so, following Smith & Wasshausen (1986) , treat the species as endemic to Ecuador and exclude the name from our treatment.
