Rayjacksonia phyllocephala is also known as...

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. Rayjacksonia phyllocephala is also known as:

Eriocarpum megacephalum | USDA symbol: ERME13
Haplopappus phyllocephalus DC. | USDA symbol: HAPH2
Haplopappus phyllocephalus DC. var. megacephalus | USDA symbol: HAPHM
Machaeranthera phyllocephala | USDA symbol: MAPH2
Machaeranthera phyllocephala Shinners var. megacephala | USDA symbol: MAPHM
Sideranthus megacephalus | USDA symbol: SIME3

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.
