Notes.

Hosseus 256 and Hosseus 606 were cited in the original protologue of S. consors (Hosseus 1907) . Hosseus 256 has seven duplicates one in each of B [B 101185735], BM [BM 000906339], E [E 00273462], K [K 001514905], L [L 2841550], M [M 0168698] and P [P 00719278] whereas Hosseus 606 has only one duplicate deposited at M [M 0168699]. M 0168698 has the original label “ Strobilanthes consors sp. nova . ” and the original description in Clarke ’ s handwriting. Moreover, this specimen has mature leaves, inflorescences and flowers. We, therefore, select the sheet M 0168698 as the lectotype of S. consors .
