 A much-branched shrub, 8 to 10 feet high, growing plentifully 

 by the side of the path ifl a salt or brackish marshy spot near 

 Tai turn tuk, T. Sampson, May 19, 1870. Widely spread through- 

 out Southern Asia, Oeylon, the Malayan and Philippine Islands, 

 and Eastern Tropical Australia. There is a single sheet only of 

 this in Mr. Sampson's herbarium, with flowers of both sexes and 

 ripe fruit, but merely half a dozen leaves, the plant being hys- 

 teranthous.

 In the very rocky bed of the stream above the bridge at Tai tam 

 tuk, first discovered by the late Dr. Harland and myself, flowering 

 in June, fruiting in October, 1858. Not certainly known to occur 

 out of the island (Exsicc. n. 322). By the great development 

 of the ovary-rudiment, this is far more nearly allied to S. ja- 

 ponica, J. MiiU., than to -B. sempervirens, Linn. ; but it differs by 

 its much longer and narrower leaves, longer less stout filaments, 

 shorter anthers, and long styles. The horns of the capsule are 

 more slender and recurved than in B. sempervirens ; and the very 

 delicate closely placed branching veins with which the upper 

 surface of the leaves is marked are not found in either. Suscus 

 chinensis, Link, cited as a synonym by Mr. Bentham, is Sim- 

 mondsia eaUformca, Nutt., placed near Buxus by J. MiiUer, but 

 located in GarryacesB by Le Maout and Decaisne (' Traite Grgn. de 

 Bot. 255), and doubtfully by Nuttall. Both Baillon and Mueller,
