42649 to 42673— Continued. 



from one-third to five-eighths of an inch wide, tapering at the base to 

 well-developed stalks one-eighth of an inch long ; dark lustrous green 

 above, glaucous beneath. In the richness of its verdure combined with 

 a remarkable elegance of form, this bamboo is probably the loveliest of 

 all its kind. (Adapted from W. J. Bean, Trees and Shrubs Hardy in the 

 British Isles, vol. 2, p. 150.) 



42661. Phyllostachys pubescens Houzeau. Poaceae. Bamboo. 



This is one of the stoutest of our hardy bamboos, the stems reaching 

 sometimes nearly 20 feet in height and bending somewhat stiffly; 1J 

 inches in diameter, deep yellow when mature. Leaves 2 to 5 inches long, 

 one-fourth to three-fourths of an inch wide, tapering or rounded at the 

 base, slender pointed, dark green above, glaucous beneath. The stems 

 when young grow with great rapidity, sometimes nearly 1 foot in 24 hours 

 in England — more in hotter climates. (Adapted from W. J. Bean, Trees 

 and Shrubs Hardy in the British Isles, vol. 2, p. 151, as P. mitis.) 



"The largest hardy species in Japan, growing to a height of over 50 

 feet and producing, not uncommonly, culms over 6 inches in diameter. 

 The culms are gently curved shortly after leaving the ground, while 

 those of other sorts with which it might be confused rise straight from 

 the base. Its sheaths are of a light-brown color, marked with dark 

 umber-brown blotches and round dots and covered with bristles. The 

 sheath spreads right and left from the base of the pseudophyll and is 

 fringed throughout with hairs which are straight when they lie between 

 the pseudophyll and the stem, but curled on the right and left sides 

 where they are free to develop. The internodes are generally shorrer 

 than those of the other large species, and the leaf sheaths are fringed at 

 the insertion of the leaf with a number of rather coarse hairs. The 

 branch buds are purplish brown and strongly marked. This is the 

 great edible bamboo of Japan and China, the method of cultivation of 

 which has been described." (D. G. Fairchild, Japanese Bamboos, Bur. 

 Plant Indus. Bui. 43, p. 27.) 



42662. Phyllostachys ptxbescens hetekocycla (Carr.) Houzeau. 



Poaceoe. Bamboo. 



The curious so-called tortoise-shell bamboo. The joints of the stems 

 near the base do not circle them in the ordinary way, but take diagonal 

 directions, the normal space between the joints being suppressed at each 

 side alternately. Thus the scars join at opposite sides alternately for 

 1 or 2 feet up the stem, when it assumes its normal form and the scars 

 become rings. (Adapted from W. J. Bran. Trees and shrub* Hardy in 

 the British Isles, vol. 2, p. 151.) 



42663. Phyllostachys pubertjla nigra (Lodd.) Houzeau. Poaceae. 

 (P. nigra Munro.) Bamboo. 



One of the handsomest of the bamboos, very distinct because of its 

 black stems, which vary from 10 to 20 feet in height and from half an 

 inch to li inches in diameter ; at first green, they become with age quite 

 black. Leaves in plumose masses, usually 2 to 3$ inches long, one-fourth 

 to five-eighths of an inch wide (sometimes larger) ; of thin texture, 

 dark green above, rather glaucous beneath. (Adapted from IF. J. Bean, 

 Trees and Shrubs Hardy in the British Isles, vol. 2, p. 152.)
