xi, c, 2 Merrill: Notes on the Flora of Borneo 71 
Sepals 5, ovate to orbicular-ovate, rounded, margins slightly 
ciliate, free, imbricate, about 2 mm long. Petals 5, free, imbri- 
cate, membranaceous, oblong-spatulate, about 5 mm long, 1.7 
mm wide, rounded, base gradually narrowed, cuneate. Disk 
glands none. Stamens 8 or 10, in two verticels, entirely free, 
all inserted on the disk ; anthers ovate, apiculate, introrse, longi- 
tudinally dehiscing, about 0.7 mm long, the filaments of the 
shorter anthers about 0.4 mm long, of the inner about twice as 
long. Rudimentary ovary present, consisting of three, free, 
slender, 3 mm long styles. Pistillate racemes slenderer than the 
staminate ones, up to 15 cm long, with very few, scattered, long- 
pedicelled flowers, usually not more than five flowers to a raceme, 
their pedicels up to 4.5 cm in length, somewhat thickened upward. 
Sepals 5, more or less pubescent, imbricate, free, the outer two 
reniform-ovate, rounded, about 2 mm long and 3 mm wide, the 
inner three ovate to oblong-ovate, obtuse, about 4 mm long. 
Petals 5, free, imbricate, oblong-obovate to oblong-spatulate, 
rounded, narrowed below to the cuneate base, glabrous, about 10 
mm long, 4 to 4.5 mm wide. Disk glands and staminodes none. 
Ovary densely pubescent, composed of three cocci, 3-celled, cells 
1-ovuled; styles stout, spreading or reflexed immediately after 
anthesis, pubescent, cleft half way to the base, free or very 
slightly united at the base, the stigmatic surface papillose. 
Fruits unknown, but apparently 3-celled, and composed of three 
dry cocci. 
Sarawak, near Kuching, Native collector 412 (type), 464, 510, 563 
(Bur. Sci.). One of the sheets is marked Matang Road, August 12, 1911, 
and another Rock Road, August 16, 1911. 
A very characteristic genus and species, dedicated to J. C. Moulton 
Esq., director of the Sarawak Museum, through whose interest it was 
possible for me to secure rich collections of Bornean plants. The genus 
is probably best placed in the Clutieae-Clutiinae near Trigonostemon and 
Schizostigma. The only other genus placed here that has its anthers in 
two verticels is Trigonopleura, but Trigono'pleura and Moult onianthus 
are entirely dissimilar and not closely allied. 
The plant is strongly characterized by its opposite, short-petioled, 
penninerved, eglandular leaves; its prominent, clasping, foliaceous, ovate, 
cordate, coriaceous, persistent stipules; and its dissimilar staminate and 
pistillate racemes; besides the peculiar floral characters given above in 
the diagnosis and description.
