The California Botanic Garden made a conservation seed collection of the population of Deinandra mohavensis (Mojave tarplant) located in Short Canyon near Inyokern in Kern County, California on October 28, 2021. This is a recollection of the 1998 seed collection made by A.C. Sanders and Steve Boyd (CalBG Accession #20160), and a seed sample was sent to the National Laboratory for Genetic Resources Preservation for use in the CPC/IMLS RNA Integrity Study.
In 2021, CPC contracted California Botanic Garden to recollect seed from a population currently held in long term orthodox seed storage as part of an IMLS-funded seed longevity experiment. The National Laboratory for Genetic Resources Preservation will evaluate how germination tested viability and RNA Integrity of seed lots decline over time in storage.
Based on an September 2020 extract of the California Plant Rescue Database, California Botanic Garden holds 21 accessions of Deinandra mohavensis in orthodox seed collection. There are as many as 185883 seeds of this species in their collection - although some may have been used for curation testing or sent to back up.
Based on an August 2020 extract of the California Plant Rescue Database, California Botanic Garden has collected 10 seed accessions of Deinandra mohavensis from 8 plant occurrences listed in the California Natural Diversity Database. These collections together emcompass 481 maternal plants
Endemic to California, Hemizonia mohavensis was rediscovered in 1994 and is known from less than 70 occurrences, some of which have not been recently observed.
Found in a number of locations in California.
