Original evidence / species identification
2024 morphological/COI paper identified introduced N. palmata specimens in Japanese survey.
Illustrated research / ancestry evidence
Other taxonomic treatments
Species sometimes called Pearl-family in hobby sources; not guaranteed identity of a seller's Snowball/Snowstorm product.
Contradictions and unresolved claims
Some palmata lookalikes are separately labeled N. aff. palmata; uncertain donor species in commercial Snowstorm OE accounts.
Ecological and breeder-pedigree limits
Biological specimen identity needed before claimed palmata × davidi ornamental hybrid.
Recorded commercial founders
Not documented in cited field taxonomy
Published, counted named-color F1/F2 ratios
No controlled commercial color F1/F2 segregation table in cited source
