Densrochilum apoense is endemic to Mindanao , Philippines. As the name suggests, it was originally found from Mt. Apo , which is the tallest mountain in Philippines. Mt. Apo is located close to Davao City , the third most populous city in Philippines. Trey Sanders maintains a wonderful web site about Dendrochilum , and here is the link to information about D. apoense . The flowers are small, but each inflorescence produces 19-28 flowers, and many inflorescences are produced. The yellowish flowers with orange lips are pretty. It is a compact plant (the height of leaves+pseudobulbs are around 5cm). According to Trey's site, this species is similar to D. eymae and D. ambangense. I haven't located illustrations or pictures of these two similar species. Trey's site mentions that D. apoense can be distinguished from these two species by erose margins of the petal and lip. Entire margins mean smooth edges, and erose margins mean irregular, jagged edges. The
