Discussion | Logfia gallica is introduced in South America, Atlantic Islands, Pacific Islands (Hawaii), Australia, and probably elsewhere. Logfia gallica is readily recognized by its relatively long and stiff awl-shaped leaves. In the flora, L. gallica is relatively common in the Californian Floristic Province from southwestern Oregon to northwestern Baja California (including the Channel Islands). It is often so well integrated with indigenous vegetation as to appear native. The first known collection in the flora area was from Newcastle, California, around 1883. It had been collected throughout central California by 1935 and had occupied most of its present North American range by 1970. In the flora area, Logfia gallica tends to grow larger than in its native range. (Discussion copyrighted by Flora of North America; reprinted with permission.) |
