Spachium where the flowers are smaller and the stamens fewer, H. canadense (Figs 46, 47k), the discontinuous ring of stamens is reflected in a less regular vascular pattern; but the five fascicle traces are still present. The whole flower, however, has undergone relative vertical condensation in these sections, so that the stamens can be said to have been 'squeezed out' into a narrow Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original British Museum (Natural History).
