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.[2][3] The plant is found in the U.S. state of California as far north as Redding, and in the Mexican state of Baja California as far south as Punta Baja,[2] as well as in the northwestern corner of U.S. state of New Mexico.[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.[7][8]: 121 The range of A. palmeri overlaps somewhat with the range of Asterella californica.[3] A. palmeri is morphologically most similar to A. saccata, A. muscicola and the East Asian species A. grollei.[9]: 174
