Didymocarpus punduanus Wall. ex R.Br.

Didymocarpus punduanus Wall. ex R.Br. View in CoL , Cyrtandreae . 118. 1839. Lectotype (designated here): INDIA, Meghalaya (then Pundua), s.d., Francis De Silva in Wallich List No. 777 (K [ K001111883 digital image!]; isolecto L [ L0003220 digital image!] and W [ W0050210 digital image!]).

Notes: The name Didymocarpus punduanus Wall. ( ‘ punduana ’) first appeared as a nomen nudum in Wallich Numerical List No. 777 ( Wallich, 1829), based on Francis De Silva’s collection from Pundua. Subsequently, Brown (1839) validated D. punduanus Wall. with a brief description and mentioned Wall List , n. 777 from ‘Montes Sylhet’. Pundua is a locality in the Sylhet region (now in Bangladesh). However, Clarke ( Anonymous, 1913) noted that collections marked ‘Pundua’ and ‘Mount Sillet [ Sylhet]’ in the Wallich Numerical List were most likely collected from the ‘Khasi hills’ of the present-day Meghalaya state in India.

Weber et al. (2000) cited the type for Didymocarpus punduanus as “ Wallich 777 (K-W, W)”. However, three sheets by Wallich 777 are currently available, one each in K ( K001111883 ), L ( L0003220 ) and W ( W0050210 ), all are syntypes (Art. 9.6 of the ICN) .

The sheet K001111883 consists of two flowering and fruiting twigs, and bears Wallich’s handwritten label, “777 Didymocarpus punduana Wall. in Herb. 1824, Pundua, De Silva”, on the upper left corner. L0003220 has six fragmented leaves, and W0050210 has two detached leaves, one imperfect flowering twig, and one vegetative twig. The specimen K001111883 is well-preserved and matches the protologue of D. punduanus and is designated here as the lectotype , and L0003220 and W0050210 as isolectotypes .
