Studies on Schismatoglottideae (Araceae) of Borneo XXXIX: Schismatoglottis persistens, a new rhizomatous rheophytic species for the Schismatoglottis Multiflora Group
During fieldwork at Batang Ai, SW Sarawak, in 2004 we encountered a rheophytic rhizomatous Phymatarum-like aroid growing on shaded consolidated alluvial clay-loam banks roughly along the upper spate zone of the Sungai Pedali, a steep-banked forest stream draining into the larger Sungai Sumpa. D...

| Summary: | During fieldwork at Batang Ai, SW Sarawak, in 2004 we
encountered a rheophytic rhizomatous Phymatarum-like
aroid growing on shaded consolidated alluvial clay-loam
banks roughly along the upper spate zone of the Sungai
Pedali, a steep-banked forest stream draining into the
larger Sungai Sumpa. Despite extensive searching over
several days we failed to find the plant in flower; indeed
we did not encounter any further populations.
A living portion (collected as AR-2383) was brought
into cultivation under permit and although growing well
for several years it failed to flower until exposed to more
light, more than in the heavily shaded conditions in which
it grew in the wild. Flowering has revealed it not to belong
to Phymatarum M. Hotta but instead to be a novel
species of Schismatoglottis Zoll. & Moritzi remarkable
in possessing an extensive epigeal, rooting rhizome from
which tufts of erect leaves arise, the petioles of which
have the petiolar sheath extended into a pair of long, free,
persistent ligules, with the entire plant highly reminiscent
of Phymatarum. |
