BAMBOO 



BAMBOO 



129 



BB, Seight less than 6 ft. 

 c. Variegation white. 



14. A. Fdrtunei, A. and C. Riviere (-B. Fdrttmei, Van 

 Houtte, and var. tiariesrdto, Hort.). Height 3-4 ft. : Ivs. 

 4-5 in. long, half as wide or a little more, striped with 

 white. Jap. P. S. 15: 1535.— Loses its Ivs. in winter, but 

 quickly recovers in spring. More popular than the next 

 two species. The internodes are rarely more than 1 in. 

 apart, while In A. auricoma they are 3-5 in. apart. Var. 

 aurea, Hort., with yellow variegation, is A. auricoma. 

 Var. viridis, Hort. = A. humilis. This is an old favorite, 

 and far more common than the next 4 species. Rhi- 

 zomes are more active than the next, and demand more 

 room. 



15. B. anguatifdlia, Mitford (B. Vilmorlni, Hort.). 

 Height about 1 ft. : sts. slender, purplish or light green: 

 Ivs. 2-4 in. long, about J^ in. wide, serrate, frequently 

 variegated with white. Jap. 



CO. Variegation yellow. 



16. A. auricoma, Mitford (A. and S. FMunei, var. 

 attrea, Hort.). Height 2-3 ft. : Ivs. 5-6 in. long, about 1 

 in. wide, brilliantly variegated with yellow, softly pu- 

 bescent beneath, serrate. Jap. 



17. A. chrysintha, Mitford (-B. chrysdntha, Hort.). 

 Height 3-5 ft.: Ivs. 5-7 in. long, 1 in. or less wide, 

 nearly smooth, sometimes variegated with yellow, but 

 not so brightly as in A. auricoma. Jap. Also dis- 

 tinguished from A. auricoma by the lower surface of 

 the leaf being markedly ribbed, and lacking the soft, 

 velvety down. " Being neither frankly green nor frankly 

 variegated, it is rather a disappointing plant."— Mitford. 



coc. Variegation absent. 

 D. Arrangement of li:<!. distichous . 



18. B, dlsticha, Mitford (B. nctna, Hort., not Roxb.). 

 Height 2-3 ft. : branches numerous : Ivs. 2-2% in. long, 

 Kin. wide or less, serrate, green, produced in two ver- 

 tical ranks. Origin uncertain, A recent and rare spe- 

 cies of great interest, the distichous arrangement of Ivs. 

 being quite unique among Bamboos, and giving a very 

 distinct habit. 



DD. Arrangement of Ivs. not distichous. 

 E. Jyvs. long, 10~1S in. 



19. B. palmiLta, Burbidge. Fig. 185. Height 2-5 ft. : 

 Ivs. 10-15 in. long, 2-3J^ in. wide, bright green, sharply 

 serrate, smooth and shining above, below pale and mi- 

 nutely pubescent : longitudinal veins very prominent. 

 Jap. M. 79. 6n. 49, p. 59, shows a clump 36 

 ft. in circumference. 



20. B, tessell&ta, Munro {B. BagamdwsTcii, 

 Hort.). Height 2-3 ft. : Ivs. 12-18 in. 

 long, 3-4 in. wide, smooth and shin- 

 ing above, whitened beneath, sharply 

 serrate ; midrib prominent, and 

 bearing a tomentose line on one side 

 and Jap. G.C. III. 15: 167 ; 18:189. K.B. 23, 

 p. 269.— Produces the largestlvs. of any hardy 

 Bambusa in cult., which is especially remark- 

 able on account of its dwarf habit. Much con- 

 fused in gardens, but unnecessarily, with A. 

 Veitchii, as the tomentose line on one side 

 of the midrib is unique in B. tessellata. The 

 Ivs. are used by the Chinese for wrapping tea. 



EE. Lvs. shorter, S-6 in. (Here might be sought 

 A. pumila, No. 2.) 



21. B. pygmaa, Miq. Height %-l ft. : stems very slen- 

 der, much branched : lvs. 3-4 in. long, about K in. wide, 

 serrate, pubescent, bright green above, glaucous and 

 pubescent beneath. Jap. — The smallest of Bamboos, and 

 remarkably hardy. It is especially valuable for making 

 a thick carpet in wild places, but its rampant growth 

 makes it a nuisance in a border. The sts. are purple : 

 the nodes prominent, and furnished with a waxy, glau- 

 cous band round the base. 



22. A. himilis, Mitford {A. FMunei, var. vXridis, 



Hort.). Height 2-3 ft. : branches in 2's and 3's, long in 

 proportion to sts. : lvs. 4-6 in. long, the largest about 

 J^in. wide : internodes 2-5 in. apart. Dies down in a 

 hardy winter. A rai'e species, liable to confusion with 

 A, pumila, No. 3. 



Section II. — Tnfernodes flattened, at least on one side : 

 sheaths early deciduous. (TJie genus Phylldstachys.) 



A. Color of stems black. 



23. P. nigra, Munro {B. nigra, Lodd.). Black Bam- 

 boo. Pig. 186. Height 10-20 ft. : stems green at first, 

 but changing to black the second year : lvs. very thin, 

 2-6 in. long, 6-10 lines broad. China and Japan. M. 142, 

 and frontis. G.C. III. 15:369 ; 18:185. R.B. 23, p. 268. 

 —One of the most popular of all Bamboos, and very dis- 

 tinct by reason of its black stems. Var. punctata, Hort. 

 Franceschi, has yellowish stems spotted with black. 



24. P. violAscens, A. and C. Rivifere {B. violdscens, 

 Carr.). Height sometimes 13 ft.: stems violet, almost 

 black the first months, changing the second year to a 

 dingy yellow or brown : lvs. very variable in size, 2-7 in. 

 long, %-2 in. wide, the larger lvs. borne on young shoots 

 or on the ends of the lower branches near the ground. The 

 lvs. are sharply serrated and have a well-defined pur- 

 plish petiole. Franceschi says it is hardy, and that P. 

 bambusioides is often sold under this name. 



.AA. Color of stems yelloioish, or striped yellow. 



25. P. mltis, A. and C. Riviere (B. mltis, Hort., not 

 Foir.). Height 15-20 or more ft.: stems arched, yellow- 

 ish ; internodes at the base not short : leaf characters 

 identical with P. aurea, with which it is closely allied. 

 Japan. Gn. 17, p. 44. -The tallest of all Bamboos, but, 

 unfortunately, not one of the hardiest. 



26. P. Castilldnis, Hort. (B. Castillbnis, Hort.). 

 Unique in the genus for having both sts. and lvs. varie- 

 gated. Height 6-20 ft.: sts. 1 in. or more thick, much 

 zigzagged, bright yellow, with a double groove of green: 

 lvs. sparingly striped yellowish white, 7 in. long, 1% in. 

 wide, serrated on both margins : leaf-sheath topped by 

 a whorl of dark brown or purple hairs. Jap.— Cult, by 

 Dr. Franceschi, Santa Barbara, Calif. 



27. B. Btriita, Lodd. Height 4-5 ft.: stems striped 

 yellow and green, as thick as the thumb ; internodes 4-6 

 in. long : lvs. 6-8 in. long, %-\ in. broad. China. 



185. Bambusa palmata. 



B.M. 6079, which shows a flowering specimen with con- 

 spicuous anthers, red-purple at first and fading to lilac.
