 Fl., Fr. Dec. 5994. 



In this plant the stems are terete, with the older wood dark brown in 

 colour, the younger reddish and rugulose with larger glands ; the small 

 leaves are closely arranged up the branches, the younger shoots being 

 reddish in colour. The leaves are +7 mm. by 5 mm., but with the incurved 

 margins appear 3 mm. across ; the midrib is thick, somewhat raised on the 

 u-iderside but not conspicuous. Petiole thick and glandular, 1'3 mm. long. 

 The flowers form little subsessile cymes, or are on solitary pedicels + 1-3 mm. 

 long, with small, triangular, translucent, gland-dotted bracts at the base of 

 the calyx. Calyx-tube 2 mm. long, with obtuse lobes 1'5 mm. long and the 

 same in breadth at the base. Petals suborbicular, +2 mm. by 1'5 mm. 

 Stamens 4'5 mm. long, with minute globose anthers. Style 4 mm. long. 

 Berry black, crowned by persistent calyx-lobes, 5 mm. by 5 mm. 



This plant is nearest to M. prostrata, described above, and in the field 

 was very similar in habit and appearance. It is easily distinguished by 

 the entire glabrous and more glandular leaves, tbe longer stamens, and 

 bilocular ovary.
