31. B. undulata. Stems about three feet in height, gradually 

 tapering towards the top, seldom branching the first year, of a 

 pale green colour, quite smooth, and marked with short white 

 streaks. Leaves oblong, from four to five inches in length, 

 waved at the edges, pale green, smooth and shining on both

32. B. argyrostigma. Stems from three to four feet in height, 

 of a dull green colour, quite smooth, and marked with numerous 

 narrow white streaks. Leaves oblique, about eight inches in 

 length, dark green, quite smooth, and singularly blotched on the

33. B. odorata. Stems about three feet in height, of a pale green 

 colour, faintly striated, and tinged with crimson at the joints. 

 Leaves oblique, about eight inches in length, bright green, quite 

 smooth and shining, especially on the under side. Flowers 

 pure white, in large clusters, suspended on rather slender foot- 

 stalks, generally on .the upper portion of the stems. Syn. B. 

 suaveolens, B. sinuata. It blooms during tlie spring months. — 

 South Atnerica. 



34. B. sinuata. This is closely allied to B. odorata ; the stem, 

 leaves, and even -the flowers appear to be very much alike in 

 both species, and both bloom at tlie same season, but it differs 

 from odorata in liaving the veins on the under sides of the leaves, 

 and also a portion of the footstalks, slightly hairy. Syn. B. 

 odorata. — South America. 



35. B. nitida. Stems woody, long, and straggling, requiring 

 a trellis to keep them up, and generally becoming bare at the

 bright green colour, and smooth on both sides. Flowers pink, 

 in clusters of from twenty to thirty blooms, suspended by foot- 

 stalks about ten inches in length. — Penang. 



36. B. aptera. Very like B. odorata, except in the stems, which 

 are quite green, and apparently more disposed to branch. 

 Leaves oblique, about six inches in length, quite flat and rather 

 long pointed ; of a bright green colour, smooth and shining. 

 Flowers white, and produced in graceful clusters, similar to 

 those of B. odorata. Like the preceding it blooms during sum-

 branching, green when young, and marked with a few white
