Fimbriaria palmeri (Austin, 1875)[1]Fimbriaria nudata (Howe, 1893)[1]Asterella nudata (Underw., 1895)[1]Asterella palmeri (Underw., 1895)[1] Asterella palmeri, also known as Palmer's asterella, is a species of liverwort native to southwestern North America that can be found growing between roughly 30° and 40° north latitude.

[4][5][3] According to California bryologists William T. Doyle and Raymond E. Stotler, Palmer's asterella is typically found around chaparral, conifers, and in oak woodland in "exposed to lightly shaded summer-dry soil; usually on gentle to steep slopes.

"[6] This liverwort is usually found below 950 metres (3,120 ft) elevation, but in the southern Sierra Nevada can be found at up to 1,250 metres (4,100 ft) above sea level.

[6] The holotype was collected by Dr. Edward Palmer on Guadalupe Island off the Pacific coast of Mexico in 1875.

[3] A. palmeri is morphologically most similar to A. saccata, A. muscicola and the East Asian species A.
