Family 34. Bambusace^. Bamboo Family. 

 Tree-like perennial grasses with woody culms. Foliage leaves rather 

 broad, parallel-nerved, usually articulating with the sheath, with or without a

 axillary, usually arranged in tufts or partial whorls at the nodes of the 

 branches of the panicle. Spikelets three- to ten-flowered, rarely fewer ; 

 empty scales of involucel two to several, unequal, shorter than the glumes ; 

 flowering glumes many-nerved, awnless; palese two- to many-nerved ; lodi- 

 cules 3, remarkably large ; stamens 3-6 ; styles 2-3, often grown together 

 at the base. Fruit a free caryopsis, a caryopsis with a delicate pericarp, a 

 nut with a thick free pericarp, or a berry.
