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 Trigonopleura and Moultonianthus 

 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.
