INTRODUCTION

Owing to a serious mistake in the protologue of

Schottarum P.C. Boyce & S.Y. Wong (Boyce and Wong,

2008), the type of the generic name [Hottarum sarikeense

M. Hotta & Bogner (¡Ý Schismatoglottis sarikeensis (M.

Hotta & Bogner) Bogner & A. Hay)] renders Schottarum

a generic taxonomic synonym of Schismatoglottis Zoll.

& Moritzi and thus our intended new genus Schottarum

requires a new name. We are here publishing Schottariella

as a replacement generic name for Schottarum. To avoid

confusion with Schismatoglottis sarikeensis we also

choose a new specific epithet.

ABSTRACT.

The recent publication of the new genus Schottarum (Araceae) from Sarawak, Malaysian

Borneo (Boyce and Wong, 2008), contains a serious typification error by which Schottarum is a taxonomic

synonym of Schismatoglottis and a new generic name is required for the taxon we described as Schottarum.

The names Schottariella and Schottariella mirifica are here published.

Keywords: Araceae; Erratum; New species; Schottariella mirifica; Schottarum sarikeense;

Schismatoglottideae.

of an otherwise erect stem (rarely arising along the

length of a decumbent rhizome) Leaves several together,

spreading to arching; petiole 6-12 cm long, slender,

adaxially canaliculate especially in distal part, sheathing

only at extreme base, the wings extended into a coriaceous

very narrowly triangular persistent ligular portion 4-7

cm long, dark green tinged red, drying brown; blade

very narrowly elliptic, 10-14 cm long ¡Ñ 1-2.5 cm wide,

thinly but somewhat stiffly coriaceous, adaxially glossy

dark green, paler abaxially, the base cuneate, the apex

acuminate to caudate for 1.5-3 cm; midrib abaxially

prominent, adaxially flush to slightly impressed with the

lamina, with 5-6 extremely fine (barely differentiated

from secondary venation in dry material; flush with but

darker than surrounding tissue in fresh state) primary

lateral veins on each side, diverging at c. 45¢X; secondary

venation faintly prominent adaxially, fine and dense;

tertiary venation obscure. Inflorescence solitary per shoot

although plants usually bearing several inflorescences in

sequence from separate but densely aggregated shoots;

peduncle 3-8 cm long, stiffly arching-spreading in nature

(where plants occur on vertical mud banks) but erect in

cultivated plants grown in pots. Spathe weakly nodding

by slight down-curving of lower part, 4-6 cm long; lower

spathe narrowly ovoid, slightly down-curved, deep green,

1.5-2 cm long, and in the main differentiated on colour

and texture (lower spathe stiffly coriaceous, spathe limb

somewhat softly coriaceous) from the limb and weakly

differentiated by a constriction; limb pale to mid-pink

or less often white, caducous, ovate-lanceolate, spathe

slightly inflated and gaping during female anthesis, then

spreading during male anthesis, narrowed into a beaked

tip throughout, during late anthesis limb marcescent

from the margins inwards and downwards and then, with

the portion closest to the abscission layer still fresh, the

spathe limb shedding. Spadix subcylindric, 3-3.5 cm

long; female zone 1-1.2 cm long, dorsal (in relation to

spathe) side of female zone adnate to the spathe, c. 5 mm

diam.; pistils gibbous-cylindric to ellipsoid-oblong, c.

1 mm diam.; stigma sessile, discoid, c. 1 mm diam. and

slightly overtopping the ovary, papillate at anthesis, deep

pink; interpistillar staminodes absent from among the

pistils, confined to a row along the spathe/spadix adnation

and occasionally a scattered individual amongst the

two lowermost rows of pistils, stipitate, weakly clavate,

slightly exceeding the pistils, white; sterile interstice

confined to about 2 irregular whorls of sterile stamens

at the base of the male zone, white; male zone c. 1 cm

long, rather narrower than the female zone, c. 3 mm

diam.; stamens crowded, rather irregular in shape and

size, ellipsoid to dumbbell-shaped from above, c. 0.5 mm

across, partially to completely connate into groups of 2-3,

truncate and flat-topped at female anthesis but at anthesis

each theca extending a needle-like projection c. 2 mm long

and terminating with a weakly peltate ovate-triangular flap

through which pollen is extruded; occasionally a scattered

deep pink pistillode among the stamens; appendix absent

to bullet-shaped, basally isodiametric with top of male

zone, distally tapering and finally narrowly obtuse, up

to c. 0.5 cm long; pistillodes of appendix columnar, flat

topped, faintly impressed, c. 0.5 mm diam., often united

to the top into curved or sinuous groups, mid-deep pink -

very small inflorescences with spadix fertile to the apex

and pistillodes absent. Fruiting spathe unequally funnel-

form, c. 1.5-2 cm long, c. 1 cm wide across the mouth,

the margins obliquely declined towards the convolution;

fruiting peduncle arching/declinate with lower spathe

mouth held laterally or slightly downwards with the

convolution ventral in respect to the peduncle; berry

gibbous-cylindric to ellipsoid-oblong, 1-1.8 mm long,

1-1.5 mm diam., with rather few seeds, mid-green with

stigmatic remains dull brown and just overtopping the

ovary; seed ellipsoid, 1-2 mm long, 0.25-0.3 mm diam.,

very pale brown, minutely scabrid, lacking a micropylar

appendage.

Distribution. MALESIA. endemic to Sarawak in

Sarikei and Sri Aman Districts; at both localities it is

scattered and rare.

Habitat. Old secondary and fragments of primary

lowland riparian evergreen moist forest on shales.

Schottarialla is rheophytic on vertical clay-loam

riverbanks. 55-80 m asl.

Etymology. The new generic epithet is derived from the

stem of Schottarum + the diminutive suffix (-iella).

Etymology. The new specific epithet is from the Latin

on first observing the movement of the thecae horns.
