<i>Bulbophyllum colomaculosum</i> Z.H. Tsi & S.C. Chen (Orchidaceae) – an addition to the Orchid Flora of India with notes on its relationship with <i>Bulbophyllum leopardinum</i> (Wall.) Lindl. and its red list assessment

Bulbophyllum colomaculosum Z.H. Tsi & S.C. Chen [ORCHIDACEAE-EPIDENDROIDEAE-MALAXIDEAE-DENDROBIINAE] has been reinstated as a distinct species based on its unique morphological features. The species was originally described from China (Yunnan) in 1994 and later reduced to synonymy under Bulbophyllum leopardinum (Wall.) Lindl. by Chen & Vermeulen (2009). Based on the study of type materials, fresh and herbarium specimens of both the taxa it was concluded that both species are not conspecific. Bulbophyllum colomaculosum has been collected from Nagaland which forms a new distributional record for Flora of India. The species has been assessed as Critically Endangered (CR) by applying the Criteria B of IUCN (2024).
