seeds (Plate 55, fig. 55—natural size and enlarged 4 times) areoccasionally found among those of grain, grass and alfalfa from the West.They are of the same general shape as those of Poverty Weed, but are onlyyV of an inch long, more tapering and less robust, somewhat darkerin colour, the surface finely striated lengthwise; when fresh, with a graymealy covering which partially rubs off and gives them a mottled appearance.The young plant has the same habit of growth and leaf outline as the GreatEagweed, but can be recognized at once by taking hold of the stem, whichin False Eagweed is perfectly smooth, while in the true Eagweed it and theleaves are noticeably rough; when full grown, the resemblance between thetwo plants disappears. The False Eagweed bears at the top of the stem alarge, loose panicle of dark-coloured flowers, while the Great Eagweed hasmany of the leaves distinctly three-lobed and the tip of each branch endswith a long rat tail-like spike of male flowers. 50 Plate 22
