Begonia sikkimensis A.DC. var. sikkimensis Other material examined INDIA: Mizoram: Lushai Hills, Aijal, Sep. 1927, Parry 253 (K). Nagaland: Naga Hills, 19 Oct. 1885, Clarke 40906 (K); Naga Hills, Kohima, 8 Jul. 1950, Koelz 25465 (MICH). Description Plant up to 100 cm. Stem: green. Male flower: outer tepals white to pale pink; inner tepals white to pale pink. Female flower: tepals white to pale pink. Remarks This species shares lacerated leaves with B. koelzii and B. shilendrae. Begonia sikkimensis tends to have smaller glabrous leaves with shallower lacerations; also the inflorescences arise from the leaf axils rather than from the rhizome as with B. shilendrae and B. koelzii. The leaves of specimens from the study area are somewhat coarser than those of the type.
