Polemoniaceae (Phlox Family) Members of Polemoniaceae found in the Bay Area are all natives, even though many of them have become popular garden plants. Almost all are herbaceous annuals, with 5 calyx lobes, 5 corolla lobes, 5 stamens attached to the corolla, and a pistil that developes 3 seed-producing sections. On Montara Mountain, members of Polemoniaceae include: Gilia clivorum (Grassland Gilia) Linanthus bicolor (Bicolor Linanthus) Linanthus parviflorus (Common Linanthus) Navarretia squarrosa (Skunkweed) On the coastal bluffs at the edge of the Montara Mountain sea terrace, we have one very rare and special member: Linanthus croceus
