 readily distinguished from all other tall kinds by the 

 broader and larger Ivs. and by the broad, persistent 

 sheaths which almost cover the sts. It is especially dis- 

 tinguished from A. Simoni by the bud being a simple 

 fl.attish scale instead of a complex scaly one, and also by 

 the less amount of waxy bloom on the st. Particularly 

 recommended for cities.

 B.M. 7146. This is the tallest of the genus, and, next to 

 P. mitis, the tallest of all hardy Bamboos. The plant is 

 very late in beginning growth, and many of the culms 

 should be removed in order to let the strong ones ripen, 

 as weak shoots are untidy. It Howers occasionally, but 

 does not die thereafter. It has a shabby appearance 

 until midsummer, and may take several years to be- 

 come established, meanwhile sending up dwarf, slender 

 shoots and narrow foliage, but Mitford urges patience, 

 as the plant is hardy, and ultimately very vigorous and 

 handsome.

 Himal. — The great majority of the plants cult, under 

 this name are really A. Falcnneri, which has larger 

 Ivs. In a small state, A . falcata can be distinguished 

 from No. 8 only by the glabrous leaf-sheaths of the 

 latter. The flower-bearing and leaf-bearing sts. of A.
