Dalisay, Bangcaya & Sangvir. from Antique Province, Philippines, is herein described and illustrated. A detailed description, colour plates, discussion of similar taxa, information on its distribution and habitat are provided. A preliminary conservation assessment is proposed and a key to the species of Globba section Nudae subsection Mediocalcaratae is amended. KEY WORDS: Antique Province, Philippine flora, section Nudae, subsection Mediocalcaratae, Zingiberales. INTRODUCTION Globba L. is the largest of the three genera in the tribe Globbeae encompassing about 120 species distributed in Sri Lanka, India and throughout Southeast Asia as far as Australia (Leong-Škorničková and Newman, 2015; Sangvirotjanapat et al., 2019). They are found mostly in the understorey of semi-deciduous and tropical rain forests, growing a few meters away from the water (Leong-Škorničková and Newman, 2015; Sangvirotjanapat et al., 2020). The genus can be easily recognized by having a flower with a long-exserted filament which is curved and ends with an anther. Number of anther appendages can be zero, two or four which is one of the important characters to identify into sectional range. Recently, six-appendaged anthers was found in G. siamensis (Hemsl.) Hemsl., G. propinqua Ridl., G. atrosanguinea Teijsm. & Binn (Cao et al., 2018). The well-known species used as an ornamental plant are G. sheewoodiana W.J.Kress & V.Gowda and G. williamsiana Sangvir. & M.F.Newman because of their permanent and colourful bracts. In addition, some species of Globba are traditionally used by the local people of Malaysia in treating several illnesses and diseases (e.g. mouth ulcer, post-partum, asthma, food poisoning, cough and many others) and in the Philippines, Globba marantina was reported to cure inflammations (Aslam and Ahmad, 2017; Dalisay et al., 2018). At present, Philippine Globba is represented by ten species, four of them are doubtful (Pelser et al., 2011; Docot et al., 2019; Sangvirotjanapat et al., 2019). The genus is underexplored in the Philippines, however, future fieldwork will probably result in the discovery of more species either endemic or as new records from neighbouring countries. As part of our ongoing systematic studies of the Philippine Zingiberaceae, materials of a flowering Globba species were collected in the tropical forests of Sta. Ana, Pandan and Mt. Igpasungaw, province of Antique, Philippines during the first author’s botanical excursions in February 2017 and September 2018, respectively. After a meticulous examination of all protologues and available type specimens from across the Philippines and neighbouring countries, it was found that this taxon does not match any other known Globba species in Globba section Nudae subsection Mediocalcaratae (K.Schum) K.J.Williams. This new addition brings the total number of Philippine representatives of this genus to seven. Also, Globba sect. Nudae subsect. Mediocalcaratae now contains 20 species. Here, the new species from the Philippines is described and a key to the species of Globba sect. Nudae subsect. Mediocalcaratae is provided. MATERIALS AND METHODS The measurements and descriptions were based on fresh collected materials, unless otherwise indicated. The style of description follows the recent work of Sam & Ibrahim (2016) and Sangvirotjanapat et al. (2019) with general plant descriptive terminology following Beentje (2016). Identification to section and subsection follows Williams et al. (2004) and Sangvirotjanapat et al. (2019). Relevant type specimens of Globba spp. from the Philippines were examined in different herbaria (AUU, BK, BM, C, E, FI, HBG, K, L, MICH, MO, P, SING, US,
