Discussion | Densely lanate or woolly plants of Hulsea nana are referable to var. larsenii. Such plants may occur in distinct populations but can be found together with sparsely lanate and strictly glandular plants. The distribution of lanate to woolly plants appears associated with higher levels of insolation. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
Plants of Hulsea algida from the Wallowa Mountains of northeastern Oregon tend to have smaller, more lanate leaves than those elsewhere and have heads slightly larger than those of H. nana. They deserve further study. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
