When the flower buds open, early in spring, the numerous hairs on the scales or filaments (one or both) give the soft, fur-like appearance, which suggested the name "; As in the pines; pollination is accomplished by the 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 Gager, C.
