He also listed three species as endemic to Penang, namely Cheirostylis goldschidtiana, E. diluta and Zeuxine rupestris. C. goldschmidtiana and E. diluta were both not recorded by Curtis (1894) and this study but they were recorded by Seidenfaden and Wood (1992), which included the locality of the specimens studied. For E. diluta, there Fulvestrant manufacturer are two specimens belonging to this species in the Kew Herbarium (K) of which
the type was actually collected from Kedah Peak (Gunung Jerai), Kedah. Therefore, it should not be listed as endemic to Penang as claimed by Turner (1995). The second collection was from Pantai Aceh, Penang, which is not part of the Penang Hill complex. C. goldschmidtiana was recorded in Penang based
on a single record collected in 1912 at Bukit Bendera (Penang Hill) and was never collected again from here (Seidenfaden and Wood 1992). However, the same species was recently (January, 2010) collected in Baling, Kedah by Rogier van Vugt and the photographs were published online in the Website of the Swiss Orchid Foundation of the Herbarium Jany Renz which is operating Entinostat cost under the patronage of the University of Basel, Switzerland (accessed on 12 May, 2011). With this discovery, C. goldschmidtiana is no longer endemic to Penang but still an endemic to Peninsular Malaysia. Nevertheless, it is worthwhile to further search for this species
around Penang Hill, otherwise considered extinct from this location. Z. rupestris, however, was recorded by Curtis, which was based on a single record from Bukit Bendera (Penang Hill) at 700 m altitude (Seidenfaden and Wood 1992) but was not found in the present study. Unfavourable environmental condition (currently higher temperature and frequent prolonged draught) was suggested for the reason it was not found during this study, the scenario better explained by the discovery C-X-C chemokine receptor type 7 (CXCR-7) of unhealthy small plants in a small population of another species, Zeuxine affinis at Government Hill which is the highest peak of Penang Hill system. Coelogyne velutina a new species described by de Vogel in 1992 based on specimens collected by Maingay from Government Hill was the only species not recorded by Turner (1995), but this species was recollected from the same locality in this study. Bulbophyllum bisetum listed by Curtis (1894) might be of wrong identification as the distribution of this species is from East Himalaya to Northern Thailand and was never mention in Seidenfaden and Wood (1992) and Turner (1995). The comparison between the current study and that of Curtis (1894) recorded Lazertinib order almost the same number of species 88 (Curtis, 1894) and 85 (current study) with 57 (57%) species overlapped.
