Which cacti has more species, Cereus or Limnanthes?
Cereus (plant) Cereus is a genus of cacti (family Cactaceae) including around 33 species of large columnar cacti from South America. The name is derived from Greek (κηρός) and Latin words meaning "wax" or "torch". The genus "Cereus" was one of the first cactus genera to be described; the circumscription varies depending on the authority. The term "cereus" is also sometimes used for a ceroid cactus, any cactus with a very elongated body, including columnar growth cacti and epiphytic cacti.
Celastrus scandens Celastrus scandens, commonly called American bittersweet or bittersweet, is a species of "Celastrus" that blooms mostly in June and is commonly found on rich, well-drained soils of woodlands. It is a sturdy perennial vine that may have twining, woody stems that are 30 ft or longer and an inch or more thick at the base. The stems are yellowish-green to brown and wind around other vegetation, sometimes killing saplings by restricting further growth. It has tiny, scentless flowers at the tips of the branches. It has colorful, orange fruits that are the size of a pea. These fruits are poisonous to humans when ingested, but are favorites of birds. "C. scandens" roots were used by Native Americans and pioneers to induce vomiting, to treat venereal disease, and to treat symptoms of tuberculosis.
