Taxon of the Week: New Plant Species Discovered in San Luis Obispo County, California
The CNDDB's Taxa of the Week features a new species of spineflower, Chorizanthe aphanantha (Irish Hills spineflower).
An exciting botanical discovery has recently been made! A new species of spineflower, Chorizanthe aphanantha (Irish Hills spineflower), has been formally described after its discovery on the Irish Hills Natural Reserve in San Luis Obispo County. This species was found growing in rocky openings of serpentine chaparral and can occur with several other rare, serpentine-endemic taxa. So far, this new species has only been found on the Irish Hills Natural Reserve and nowhere else in the world!
The CNDDB botany program and the California Native Plant Society’s Rare Plant Program will be working together over the next few weeks to review this species for addition to the CNDDB Special Vascular Plants, Bryophytes, and Lichens List and to the CNPS Inventory of Rare and Endangered Plants.
