Microseris sp.. It is quite likely that the updated name for this genus has changed to another genus, but without the species, the new genus name is uncertain.

Vulpia sp.. Because Festuca was split up into Festuca and Vulpia, we have no way of knowing from this Flora alone whether this should be listed as Festuca or Vulpia. Since in our experience the weedy non-native Vulpia species are encountered much more frequently than Festuca species, we have chosen to change Bob's original entry of "Festuca sp." to "Vulpia sp.". Note that this could be incorrect, and anyone using this flora should beware.
