IVHEAT. 67 Pericarp (Fig. t,Z ^- i- ^^^ Epicarp (Fig. 33, epi, Fig. 35) iscomposed of colorless cells, which, except at the apex of the grain(Fig. 34, epi 1) are longitudinally elongated and are arranged end to end(but not side by side) in rows (epi^). A thin cuticle covers the outerwall (Fig. T,T,, cut). In surface view, both the side and end walls appeardistinctly beaded, the double side walls being about 4 /jl thick. At theapex of the grain the cells are nearly isodiametric, and between themarise numerous hairs (Fig. 34, /; Fig. 36) which vary up to i mm. in lengthand (measured near the ba
