Fabaceae: Pea Family — Hosackia & Lotus
The pea family has 5-petaled flowers, consisting of a wide upper banner petal, two wing petals, plus two lower petals which are fused to form a boat-shaped keel. Many produce heads or spikes, consisting of multiple individual flowers (examples are lupines and clovers). The seed pod is generally a “legume”. This is a long, flattish pod, swollen by the seeds, and splitting lengthwise along both the top and bottom.
After a recent revision, the Lotus genus includes only non-native plants. All of the native lotuses are now in either Acmispon or Hosackia.
