At 7 pm on May 20, Dr. James Smith from the Snake River Plains Herbarium at Boise State University will present recent research on spring parsley (Pseudocymopterus) that indicates the spring flowering and summer flowering populations are separate species.
Arizona Native Plant Society talks are free and open to the public. This meeting can be attended via Zoom or in person at the NAU biology building third floor classroom. To attend via Zoom, register with this link: https://bit.ly/FlagAZNPS25
Spring
parsley (Pseudocymopterus) is known to be highly variable
morphologically and in its phenology. Dr. James Smith will present
preliminary results that separate what we commonly call Pseudocymopterus
montanus into several separate well-supported clades. Likewise there
will be preliminary phylogenetic analyses that seem to separate most
other species of Pseudocymopterus (P. beckii, P. macdougallii, and P.
davidsonii) into spring flowering and summer (monsoon) flowering
populations that have independently adapted to the different
precipitation patterns.
This will be a virtual event with Dr. Smith presenting from Idaho. This presentation will not be recorded.
Dr.
Smith is the Director of the Snake River Plains Herbarium at Boise
State University. His research interests include the phylogenetics of
western North American Apiaceae and using Sanger sequencing, and more
recently Next generation sequencing techniques to discover cryptic or
near cryptic species within many widespread species.
