Primula alcalina, the alkali or bluedome primrose,[1][2] is a species of primrose found in central-east Idaho and Montana.[3]
Primula alcalina is closely related, and was once believed to be conspecific to, P. incana, the hoary primrose, but can be distinguished from that species by the size and colour of its flowers (smaller and white, as opposed to pale purple), and by cellular-level differences, having a significantly lower chromosome number.[4][5][6]
It is believed to be a sister taxon to Primula modesta of Japan.[7]
Primula alcalina has leaves measuring 1-4 cm in length with glabrous (hairless) surfaces.[8][3] It roots are fibrous and its rhizomes are thin and relatively short.[3][8] Its flowers grow on unbranched umbels at the top of a flower stem which can vary between 6.5 and 24 cm in height.[3] There can be as many as 10 flowers, which grow on purplish-green pedicels.[4]

Primula alcalina er blóm af ættkvísl lykla sem var lýst af A.F. Cholewa och D.M. Henderson.
Blöðin eru í hvirfingu, 1 - 4 sm löng, mjó oddbaugótt með bylgjóttum eðae tenntum kanti. Þau eru mjölvuð fyrst en verða slétt með aldrinum. Hvítleitur blómstöngullinn verður 6,5 til 24 sm á hæð, með 3 - 10 hvít blóm, 4 til 7 sm löng, mjölvuð.[1]
Primula alcalina er upprunnin í Idaho og Montana. Í raun er hún aðeins staðfest í Beaverhead County. Hún hefur ekki fundist aftur á upprunalegum fundarstað sínum. Hún vex í votum basískum engjum í 1900 m til 2200 m hæð yfir sjávamáli.[1]
