Cicuta [SEP] parent taxon
Cicuta
Cicuta, commonly known as water hemlock, is a genus of four species of highly poisonous plants in the family Apiaceae. They are perennial herbaceous plants which grow up to tall, having distinctive small green or white flowers arranged in an umbrella shape (umbel). Plants in this genus may also be referred to as cowbane or poison parsnip. "Cicuta" is native to temperate regions of the Northern Hemisphere, mainly North America and Europe, typically growing in wet meadows, along streambanks and other wet and marshy areas
- "Tachypompilus ferrugineus torridus" , the Sonoran Desert and adjacent regions of southern California, southern Utah, southwestern New Mexico, western Texas south to Chiapas, Mexico
However, the subspecies "T.f. nigrescens" from the northeastern United States may be a melanistic morph of the nominate subspecies rather than a valid taxon in its own right.
