Schismatoglottis mons Kartini, sp. nov.
Diagnosis: The inflorescence of Schismatoglottis mons is most similar to that of rheophytic S. gillianiae. However, S. gillianiae has a very short peduncle (c. 2-3.5 cm long-, fleshy persistent ligular petiolar sheaths and narrowly oblanceolate leaves whereas S. mons have long peduncle c.10 cm, a marcescent free ligular petiolar sheath and ovate to oblong-ovate leaves. Schismatoglottis mons differs from mesophytic S. shaleicola by the inflorescence peduncle up to 10 cm long, the yellow spadix, a slender cylindrical appendix about twice as long as remainder of spadix, pink sterile interstice
Etymology: Mons, Latin meaning mountain, and referring to the occurrence of the species at altitude.
