The spikeletsof Arundinaria japonica are large and only bamboo native in the United States is the wildcane {Arundinaria macrosperma Michx.) (Fig. 63), foundin our southern states where it often forms large massescalled cane-brakes. A small form of this or possibly adistinct species, A. tecta Muhl., is called small cane orscutch cane. The floral characters of the bamboos are of little importanceto students, as the cultivated forms do not often flower. The criticalstudy of the group is too technical for any but the expert. Thestructure of the spikelets is, however, comparatively simple. They 248 A TEXT-BOOK OF GRASSES. Fig. 63. Arundinaria macrosperma.
