= Cheirostylis chinensis var. glabra Bhaumik & M. K. Pathak in Bull. Bot. Surv. India 47: 183. 2006.

Typus: INDIA. Arunachal Pradesh: Dibang Valley district, Bejari , 150 m, 5.III.2004, Bhaumik & Tham 104752[A] (holo-: CAL!; iso-: ASSAM!, 2 sheets [B] [C]), syn. nov.

Specimens examined. – INDIA. Arunachal Pradesh: Lohit District, Minzong-yasang, 3.X.1985 [flowered on 11.III.1986 at Sessa], A. N. Rao 21463, 21489 (Orchid Herbarium Tipi); West Kameng District, 2 km from Munna Camp (towards Dirang ), 1491 m, 16.IV.2006, A. Bhattacharjee 34819 A, 34819 B ( CAL) .

Note. – BHAUMIK & PATHAK (2006) described C. chinensis var. glabra based on collections from Arunachal Pradesh and distinguished it from the type variety in having glabrous bracts and ovary, acuminate petals and epichile with 2 broad green patches at the base. But these authors overlooked the earlier described C. moniliformis which is identical ( Fig. 1 ) with their variety. Thus, C. chinensis var. glabra is treated here as a heterotypic synonym of C. moniliformis .
