Which has more species, Ecballium or Brownea?
Ecballium Ecballium is a genus of flowering plants in the family Cucurbitaceae containing a single species, Ecballium elaterium, also called the squirting cucumber or exploding cucumber (but not to be confused with "Cyclanthera explodens"). It gets its unusual name from the fact that, when ripe, it squirts a stream of mucilaginous liquid containing its seeds, which can be seen with the naked eye. It is thus considered to have rapid plant movement.
Eriogonum heracleoides Eriogonum heracleoides (common names parsnipflower buckwheat, whorled buckwheat, and Wyeth buckwheat) has many flowering clusters that are cream or off-white in color. Its usual habitat is rocky areas such as sagebrush deserts and Ponderosa pine forests. Parsnipflower buckwheat is in the genus "Eriogonum" and the family Polygonaceae which is a family of plants known as the "knotweed family". It inhabits much of the western part of the United States.
