Eschscholzia ramosa E. Greene


Eschscholzia ramosa - plant This species, called "Island poppy" on the California Native Plant Society Rare and Endangered Plant Inventory, occurs on the California Islands, from San Miguel Island south to Cedros Island, and possibly on Guadalupe Island. It is similar to E. caespitosa, but the divisions of the leaves spread at a greater angle, giving the foliage a very different appearance. It is a tetraploid, with a chromosome number of n=12, and may be a polyploid derivative of a mainland species, perhaps E. caespitosa.
