Geoffary Gunsalam and I found this epiphyte growing on Gunung Alab, in Tambunan (Sabah, Malaysia). The plant was sterile, and we were unable to place it to genus at the time. I did not collect it since my permit only covered grammitids. A few weeks later while working in SING I stumbled upon some Asplenium specimens which were quite similar and realized what I had seen. Thanks to Barbara Parris (AK) for suggesting the species.
