Primula rusbyi is a species ofPrimula.[4] Acommon name isRusby's primrose.[5]
This species was first collected byHenry Hurd Rusby in theMogollon Mountains in theNew Mexico Territory of the time (now the stateNew Mexico),Edward Lee Greene used these specimens as theholotype with which todescribeP. rusbyi in 1881.[1][6]
The species occurs from the southernRockies in the United States throughMexico probably down to northernGuatemala.[3] In the USA it occurs inArizona andNew Mexico.[3] Although the range in the USA appears to be split intodisjunct populations,[5][6] this may be an artefact of ignoring the Mexican distribution.
Some plants from theSandia Mountains of New Mexico have a longercorolla than thecalyx, unlike thenominate type;[3] these were described asPrimula ellisiae in 1902 byTheodore Dru Alison Cockerell from a 1900 collection byCharlotte Cortlandt Ellis in the area of her family's ranch.[6][7] However, individual plants with this phenotype grow together with plants having the normal form flowers, and no genetic distinctiveness was found between forms.[3]
