Bulbophyllum patens is another widely found lowland orchids in Malaysia. An epiphyte orchids normally found on tree barks. Unfortunatelt, until todate I havent have the opportunities to see in in situ. Normally the in situ situation is at the roadside stalls operated by the aborigines.
The single lightly scented flowers have a straight lip that is highly mobile, where this on of many reason the flowers will get easily pollinated by insects.
The bulb to the end of leaf normally around 15 cm with stiff leaf. A hot growing species that requires, hot conditions, shade, frequent waterings and fertilizings as well as high humidity.
