278 MOULTONIA t A NEW BORNEAN GESNERACEOUS GENUS. 
Moultonia singularis, Balf. fil. et W. W. Sm. 
A stout herbaceous plant with a single leaf; stem above 
ground none ; petiole 80-40 cm. long, 1 cm. or more in 
diameter, striate, with a limy scurf over the whole surface, 
channelled above and bearing flowers in the channel; the 
lamina of the leaf 80-85 cm. long, 20-30 cm. broad, ovate 
or oblong-ovate with cordate base (apex not seen), entire, 
in the living state no doubt fleshy, above dark green 
glabrous, below covered with a rough limy scurf; midrib 
channelled above bearing numerous flowers throughout 
almost its whole length, below showing a stout projecting 
ridge 5 mm. broad or more ; the primary nerves 20-30, 
very conspicuous and sub-parallel, 1-3 cm. distant from 
one another, given off from the midrib at a right angle 
and much bent on approaching the margin. Peduncles 
very short, 1-3-flowered; pedicels 3-4 mm. long, lengthened 
in fruit to 1 cm., covered with a limy scurf; bracts and 
bracteoles very small, only about 1 mm. long and some¬ 
what fleshy. Flowers small, arising in the furrow of the 
petiole and in the furrow of the midrib, forming an almost 
continuous line. Calyx bell-shaped about 4 mm. long, 
slightly enlarged in fruit, deeply 4-cleft; lobes slightly 
imbricate, erect, closely appressed in fruit, oblong, more or 
less obtuse with membranous margins, on the outside with 
limy scurf, on the inside with a definite limy cushion. 
Corolla small (no fully developed specimens available for 
examination) ; tube short, limb bifid, the posterior lip 
bifid, the anterior lip (seen only in the bud) undivided, 
but in the developed flower this lip will probably be trifid. 
Perfect stamens 4, sub-equal, about 1 mm. long inserted 
in the middle of the tube; filaments dark coloured, glabrous, 
about ^ mm. long; anthers all cohering laterally, in shape 
reniform or almost ear-shaped, scarcely 1 mm. in diameter. 
Disc cup-shaped, reaching almost to the middle of the 
ovary. Ovary superior, globose, with a linear style a little 
longer than the ovary and a small truncate stigma. The 
lower and seed-bearing half of the mature fruit globose, 
about 1J mm. in diameter, with its walls membranous and 
easily broken, apparently scattering its seeds by an irregular 
transverse rupture ; the upper part of the capsule forming 
a narrow cone suggesting somewhat the top of a moss 
capsule, about 4 mm. long and at the base about 1 mm. 
broad, solid, and at maturity protruding a little from the 
enclosing segments of the calyx. Seeds very numerous, 
ovoid or rounded or sometimes more or less quadrate and
