from 5 to 4 inches—perhaps hardly as much—the width not 
much more than half an inch; the colour a bright cheerful 
ereen on the upper face, glaucous on the lower. The leaf 
sheaths are of a purplish colour, fringed at the insertion of 
the leaves with hairs on the sides of an elongated ligule. 
The rootstock is extremely active, and when once well 
established the plant spreads rapidly, new culms appearing 
at some distance from the parent stock. 
The culms have grown to a height of 18 feet at Shrub- 
land and nearly 15 feet at Kew, with a circumference 
of no more than 2 inches: They are very hollow and as a 
consequence extremely brittle and apt to split. A stem 11 
feet high and nearly 2 inches in circumference has a pipe 
about three-eighths of an inch in diameter, the wall measuring 
only one-eighth of an inch. 
The species is perfectly hardy when once established, and 
has stood uninjured through our severest winter. Yet it is 
necessary to be cautious in planting it out after travelling. 
I have lost a good many plants by over great confidence 
in this respect. Newly arrived plants should be carefully 
potted and remain for their first winter under the protection 
of a temperate house, according to the recommendations 
given in my general remarks upon Culture. 
Thus, to the best of my ability, I have endeavoured to 
point out the leading features of this pretty Bamboo as they 
appear in this country. In warmer climates, according to 
Messrs. Riviere, the plant has a very different aspect. The 
culms are stouter, straighter, and rounder, the internodes are 
longer, the knots more pronounced, and the third branchlet, 
which is so common in the north, is abortive, owing to the
