LECTOTYPIFICATION

Fischer (1926) described Petrocosmea parryorum , based on the collections of Mr. and Mrs. Parry and cited “ INDIA. Assam; Lushai Hills , about 1700 m., near Sailsuk, Muallung, on the Chin Hill border, and Vanlaiphai, Sept.-Nov., Mr. and Mrs. N. E. Parry (type in Herb. Kew.)”. We have traced four relevant sheets at K ( K000196635 , K000196636 , K000196637 , K000196638 ), that seem to come from three collections: K000196635 and K000196636 were from Muallung while K000196637 from Vanlaiphai, all three collected on 3 November 1925, and K000196638 from Sailsuk collected in September 1925. The sheet K000196636 has two plants, a single leaf and inflorescence and a separately mounted flower. The plant on the right has a flower with a 6-lobed corolla, which is an exception. K000196637 and K000196638 each hold a small single plant and a separately mounted leaf. The former has no flowers but infructescences separately placed in an envelope on the sheet, while the latter plant has flowers and illustrations. K000196635 having five flowering plants on the sheet with five leaves are mounted separately and a flower in a pocket is selected here as the lectotype.
