Notes: Previously on List 1B. Plants from MNT and SCR counties need verification. Threatened by coastal development and non-native plants. Can be difficult to identify; many herbarium specimens need to be checked for correct identification. May be a hybrid between G. hirsutula var. hirsutula and G. stricta var. platyphylla or G. stricta var. angustifolia; needs further study. Not in TJM 2. See Pittonia 2:289 (1892) for original description and Novon 2(3):215-217 (1992) for revised nomenclature. |
