Often we refer to plants by their common names. When shopping for plants the scientific name is the best way to positively identify the plant species you desire. But some plants have more than one name! While it doesn't happen often, nurseries might display one name while you're searching for another. Dichanthelium oligosanthes var. scribnerianum is also known as:

Dichanthelium oligosanthes Gould var. helleri | USDA symbol: DIOLH
Panicum helleri | USDA symbol: PAHE8
Panicum macrocarpon Leconte ex | USDA symbol: PAMA14

Panicum oligosanthes var. scribnerianum | USDA symbol: PAOLS
Panicum scoparium Watson ex Nash, non | USDA symbol: PASC10
Panicum scribnerianum | USDA symbol: PASC5

Why do some plants have more than one name? Over time plant species may be renamed for a few reasons:

  1. Botanists in different regions named the same plant without knowing it had already been classified.
  2. A species was reclassified after scientific advances in, for example, DNA analysis.
  3. Slight variations within a species are sometimes mistakenly identified as entirely new species.
