Araceae of Mulu National Park. I. Four new species of Schismatoglottis (Araceae)

Abstract

Four new species of Schismatoglottis are described and illustrated from Mulu National Park in Malaysian Borneo: Schismatoglottis fossae (Patentinervia Clade), S. roseopedes and S. serratodentata (Calyptrata Clade) and S. pellucida (currently unplaced but likely in the Multinervia clade). A brief summary is provided of botanical exploration at Mulu, notably where pertinent to aroid botany.

Studies on Schismatoglottideae (Araceae) of Borneo LXIX: Schismatoglottis imbakensis, a new species of the Patentinervia Complex from ultramafic rocks, Sabah

“…The Schismatoglottis Patentinervia Clade is entirely Bornean (Wong et. al., 2017(Wong et. al., , 2019, comprising small mesophytic herbs with highly distinctive lanceolate to oblong-elliptic to narrowly obovate leaf blades lacking posterior lobes, and with ladder-like rather closely spaced numerous primary lateral veins diverging from the mid-rib at about 90°.…”

“…al., , 2019, comprising small mesophytic herbs with highly distinctive lanceolate to oblong-elliptic to narrowly obovate leaf blades lacking posterior lobes, and with ladder-like rather closely spaced numerous primary lateral veins diverging from the mid-rib at about 90°. At present the clade comprises 11 described species, 8 of which have been described in the past three years (Boyce 2017;Wong et al 2017Wong et al , 2018Wong et al , 2019. Until now, only one species of the Patentinervia Clade has been recorded from Sabah, Schismatoglottis retinervia Furtado (1935), restricted to the vicinity of Kinabalu between 1000 and 1600 m asl on granite.…”
