These bulblots represent an important means of vegetative reproduction since they are able to develop new individuals when separated from the mother-plant, thus reminding of S. cernua L. of the section Nephrophyllum. When the bulblet germinates, it produces a short, ascending rhizome, terminated by a rosette of typical leaves, and an inflorescence bearing few flowers but many 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 Canadian Arctic Expedition (1913-1918).
