Polygonaceae: Knotweed Family — Eriogonum (Buckwheat)
Flowers in this family do not have separate petals and sepals. For plants like this, the term “perianth” is used to describe the flower (i.e. the calyx and the corolla together) and “perianth parts” to describe the individual elements. Buckwheats are a very large and diverse group of plants, with almost 40 species found in Monterey, and about 120 in California. Not surprisingly, identification can prove challenging. Many of the flowers are quite similar, so you should pay attention to the leaves and growth habits instead. Beyond a certain point, a good botanical key is indispensable.
