Discussion
Melampyrum lineare has been divided into four varieties on the basis of vegetative traits: leaf shape and margin, internode length, and degree of branching (or bushiness). Without exception, circumscriptions are overlapping for these traits, none of which is strictly diagnostic. Authors are also not in agreement about which varieties to recognize. Geographic ranges of the varieties are largely confluent; much of the morphological diversity of M. lineare is present throughout the range.
Melampyrum lineare is an obligate parasite insofar as it does not flower or fruit without a host (J. E. Cantlon et al. 1963). It parasitizes primarily woody plants, including Acer saccharum, Pinus banksiana, P. resinosa, P. strobus, P. sylvestris, Populus grandidentata, P. tremuloides, Quercus rubra, and Vaccinium angustifolium.
