In a microscopical examination of a powdered sample of Asclepias tuberosa. the most numerous elements are the stone cells, varying in size from .06 to .25 millimeter in length and from .09 to .12 millimeter in width. They are al- most circular, with very thick walls and small empty cavities, circularly striated, â of light yellow color, and have small pores. They occur most frequently in pairs, but are also seen in masses. Next in prominence are the large, yellow bast fibers, as m,uch as milli- meters in length and .25 millimeter in width, very finely striated and porou^ with a small central cavity. The wallr, are rough and very thick, giving the ap- pearance "of a dark outline surrounding /I.
