216 ARUNDINARIA 



previous decade. It forms thickets of stems of great density, but spreads 

 rapidly, and can be increased very quickly by division. In the earlier days of 

 its cultivation in Britain I regarded it as a variety of A. Hindsii, but in twenty 

 years these two have assumed very different characters. A. graminea is a 

 much more slender, leafy plant, hardier, and better for gardens ; the leaves 

 are only half as wide, and the secondary veins fewer. 



A. HINDSII, Munro. KAN-ZAN-CHIKU. 



(Bambusa erecta, Hort?) 



Stems tufted, 8 to 10 ft. high, round, quite erect, up to I in. diameter ; dark 

 olive green; at first covered with a waxy bloom; joints often 8 to 10 ins apart; 

 central pipe large. Branches erect; forming dense clusters at eacl joint. 

 Leaves mostly erect, dark green above, rather glaucous beneath, smooth 

 on the surfaces, but with numerous bristle-like teeth on one margin and a 

 few scattered ones on the other ; the longest are 8 to 9 ins. long, the broadest 

 f to i in. wide ; the average width is from j to f in., tapered at tre base, 

 the apex long, tail-like. Secondary veins four to six each side the midrib. 



Native of Japan; cultivated in England since about 1875. It lowered 

 in 1910 and 1911. It is one of the least elegant of bamboos, sinilar in 

 foliage to A. graminea, but less copiously leafy and with larger leaves. The 

 stems and leaves are also stouter and darker green, the habit is less dense, 

 and the plants do not " run " so rapidly. 



A. HUMILIS, Mitford. 



(Bambusa Nagashima, Marliac^ 



A dwarf, rapidly spreading bamboo, 2 to 5 ft. high as a rule ; stems very 

 slender, and with a minute hollow up the centre. Leaves bright green on 

 both sides, 2 to 7 ins. long, \ to f in. wide, rounded at the base slender- 

 pointed ; secondary veins three to five each side the midrib ; leaf-sh<aths with 

 two clusters of bristles at the top. 



A native of Japan, long grown in gardens as A. Fortunei ("grem form"). 

 The true A. Fortunei is well marked by its white-variegated leave. I am, 

 however, unable to see any real distinction between it and the Bambusa 

 Nagashima of French nurserymen ; nor is there much to choosi between 

 these two and A. chrysantha, except the occasional variegaticn of the 

 last. A. humilis, without possessing any special merit, forms pleasant 

 masses of greenery from midsummer onwards. 



A. JAPONICA, Siebold. MDAK. 



(Bambusa Metake, Siebold.') 



Stems 10 to 12 ft. high (5 or 6 ft. more in the milder countfis), round, 

 very hollow, erect, ^ to f in. diameter, with erect branches nea- the top, 

 producing only a few leaves the first year. Stem-sheaths neary as long 

 or longer than the space between the joints, which is sometimes ! ins., very 

 persistent, soon turning pale brown, covered at first with flattend bristles ; 

 terminated when young by an awl-shaped tongue up to 3 ins< long, but 

 only in. wide. Leaves 7 to 12 ins. long, f to 2 ins. wide, terminated by 

 a long, tail-like point ; the upper surface glossy dark green ; rathff glaucous 

 beneath, except a strip about one-fourth of its width near one majgin, which 

 is green. There are five to nine secondary veins each side the midri), minutely 

 tessellated with cross veinlets; one margin is minutely, the other scare ly toothed.
