 yellow: sheatlis early ileriduoiis, the Hgule extendeil 

 into fringeti auricles: Ivs. 3—1 in. long, about 32in. wide 

 or a little more, bright green above, whitened below.

 Sieb. & Zucc. Height 

 6-10 ft.: sts. slender, zig- 

 zag, green at first, event- 

 ually yellowish : sheaths 



Eurplish, early deciduous; 

 ranches in 3's, the long- 

 est in the middle, httle 

 longer than the internodes: 

 Ivs. variable, 5-' 

 in. long, 1 in. ^ 

 or less wide, ser- 

 rate, the teeth 

 especially sharp 

 on one edge, 

 bright green, 

 pale beneath. 

 China and 



Japan. Gamble, Bamb. Brit. Ind. 27, t. 

 27. — The true plant very rare in cult. 



cc. Plants low, 1-3 ft. high. 



30. P. ruscifolia, Hort. Kew (P. 

 Kianasdca, Mitford. P. Kumasdca, 

 Munro. B. ruscifolia, Sieb. B. vimina- 

 lis, Hort.). Fig. 460. Height 1-3 ft.: 

 sts. zigzag, dark to pale green : sheaths 

 purple, much fringed: branches very 450. Phyllostachys 

 short, not more than 1 or 2 in. long, in ruscitoUa. (x-rs) 

 3's and 4's: Ivs. 2-3 in. long, about 1 



in. wide, ovate in outline. Japan. G.C. III. 1.5:369; 

 18:189. — The sts. are almost solid, the tube being ex- 

 ceedingly small. Dwarfest species of Phyllostachys. 



Section II. Venation essentially striate, i.e., the veins 

 running in parallel lines from the base to the apex, 

 cross veins ob-mlete or obscure, but itsiially with a 

 number of interposed pellucid dots. (Embraces 

 the less hardy types of bamboos, 31-41.) 



A. Sts. hollow, not spiny. 

 B. Lvs. averaging not more than 3 in. long. 



31. A. nobilis, Mitford. Height 1.5-25 ft.: Ivs. 2-3 

 in. long, usually less than J2in. wide, bright green, 

 borne on short, purjile petioles, striate-veined : sts. 

 yellow-green, with purple-brown nodes. Probably a 

 native of China. — .\ large and graceful species intro. 

 into Calif, by Francesehi in 1896. One of the hardiest 

 of the arundinarias with striated lvs. 



32. A. debilis, Thwaites. Height probably .5-10 ft.: 

 sts/ clustered, much branched, the nodes 2-6 in. apart, 

 yellowish: lvs. 1-3 in. long, i-|in. or less wide, striate- 

 veined. High mts. of Ceylon and the Philippines. 

 Gamble, Bamb. Brit. Ind. 7, t. 6. — Intro, in Calif, and 

 offered in 1910 by the Montario.so Xursery. The char- 

 acter of the venation would seem to imply only 

 moderate hardiness. 



BB. Lvs. averaging not more than 6 in. long. 



33. A. Falconeri, Benth. (T. Fdlconeri, Hook. f. 

 B. griicilis, Hort., not VVall.J. Height 10-1.5 ft.: sts. 

 slender, bright green when young, yellow when old, 

 the internodes sometimes white-waxy: lvs. thin, 3-4 

 in. long, about M'n. wide, striate-veined. Himalayas. 

 Gamble, Bamb. Brit. Ind. 20, t. 18. B.M. 7947.— Not 

 ver>' hardy. The If.-sheaths are smooth, cut short at 

 the top, without a fringe, and with an elongated ligule; 

 while A.falcala has very downy If.-sheaths, fringed with 

 long hairs at the intersection with the If. The serra- 



tions of the If. -edges are more pronounced in A. 

 Falconeri, especially on one side. 



34. A. falcata, Necs (B. falcata, Hort.). Height 10- 

 20 ft.: lvs. 4-6 in. long, about 3 sin. wide, light green, 

 striate-veined: sts. slender, not exceeding J-^in. diam., 

 covered with a bluish white-waxy coating when young, 

 eventually yellow-green: sheaths downy, ciliate at the 

 ligule. Himalayas. Gamble, Bamb. Brit. Ind. 12, t. 

 1 1 and 12. — A great many plants cult, under this name 

 are really A. Falconeri, a species with smooth sheaths 

 and fringeless hgules. Requires a mild chmate. 



BBS. Lvs. averaging more than 6 in. long. 

 c. Culms 15-25 ft. tall, reddish brown 



at maturity. 



35. A. Hookeriana, Munro. Height 



15-25 ft.: culms glaucous green when 



young, turning reddisli brown with age: 



nodes prominent, with a bluish ring: lvs. 



6-10 in. long, }2-l)'2 in. wide, the venation 



striate. Himalayas. Gamble, Bamb. Brit. Ind. 17, t. 



15. — The tallest and largest species of arundinaria in 



cult. Intro, in Calif, by Francesehi. Not very hardy. 



Culms taller; giant species: sts. green or yellomsh. 



36. B. vulgaris, Schrad. Feathery Bamboo. Height 

 20-80 ft.: sts. bright green, 4 in. diam., or more, 

 straight at first, eventually much arched by the weight 

 of the dense foliage: branches numerous, striate: lvs. 

 usually 6-10 in. long, 8-15 lines wide, rough on and 

 near the margins and on the lower surface. India. 

 G.C. III. 25:390. Gamble, Bamb. Brit. Ind. 44, t. 49. 

 Var. aftreo-variegata, Hort., Golden Bamboo, has 

 canes of a rich golden yellow color, penciled with green. 

 — Will stand but slight frost. 



37. D. Hamiltonii, Nees & Am. Height up to 80 ft.: 

 sts. 4-7 in. diam., much branched above, pubescent 

 with white hairs when young: internodes 12-20 in. 

 long: lvs. variable, sometimes 15 in. long, 2^2 in. wide, 

 finely serrate; midrib narrow, with 6-17 nerves on 

 either side, the nervules chiefly of pellucid glands. 

 Himalayas. Gamble, Bamb. Brit. Ind. 85, t. 74. — 

 The lower branches usually seated on woody knobs. 

 Promises to become an import-ant member of the tall 

 bamboos in S. Calif. 



38. D. latiflo- 

 rus, Munro. 

 Height 60-70 

 ft. : sts. erect 

 and remarkably 

 straight, 4-5 in. 

 diam., with a 

 large cavity: lvs. 

 7-10 in. long, 

 1-2 in. broad, 

 long-acuminate, 

 deep green, 

 borne on short 

 petioles; midrib 

 prominent, with 

 about 9 nerves 

 either side, the trans- 

 verse nervules lacking 

 or obscure. Formosa, 

 Burma, Cochin China. 

 Gamble, Bamb. Brit. 

 Ind. 131, t. 117. 

 Munro, Trans. Linn.

 Considered one of the 

 best of the giant bam- 

 boos in S. Calif

 ceus, Munro. Height 46I. Bambusa arundinacea.
