Dyckia alba and Dyckia ursina are the only two Dyckia species to present
a cotton like structure among their flowers.
Bothshould have got much better and significant valid names. Alba is a name used when a plant present paler or white flowers and belong tho a very same species that bears darker normal flowers. For instance Dyckia fosteriana alba would be the name of a variety of Dyckia fosteriana with white or paler colored flowers. ( This does not exist or was not found yet.)
This baby here has no white flowers and no paler than any.
This is a name suited for a variety and not a species.
But..... remember taxonomist got their spouses hat appendices to classify a bird they insisted to be refugees from paradise and had no foot and also the female hatched their eggs on the male´d bach ´cause they were ever on flying....Pardisea apoda.
Dyckia ursina have the same cotton structure among its flowers only chestnut colored and science took it as very similar to the bear fur. Ursina is Latim for like a bear.
Maby science has never saw a bear or was all too imaginative here.
