        An “*” indicates non-native taxa that have become naturalized or persist without cultivation.
        A ? indicates unknown taxa (either species or subspecific rank), i.e. the identify of the plant is not fully known.
  Habit definitions:
      AF = annual fern or fern ally. PG = perennial grass or graminoid.
      AG = annual grass or graminoid. PH = perennial herb.
      AH = annual herb. PV = perennial vine.
      BH = biennial herb.    S = shrub.
      PF = perennial fern or fern ally.   T = tree.
Voucher notes:  Listed are one voucher specimen, including the collector’s name, collection number (or date of collection)
     and herbarium acronym where it has been deposited.
Floristics:
     # of taxa = 386 # supported by voucher specimens = 255
     % native = 71.5% (276) % of flora supported by vouchers = 66.1
     % naturalized = 28.5% (110) # of families represented = 71
