Menyanthaceae
The ANHAT database has 4493 records for 29 species and subspecies of
Menyanthaceae. No species of Menyanthaceae are considered extinct.
Four species account for approximately 50% of the total species records in ANHAT (
Table 292). These species have over 300 records each.

species records for this family in ANHAT.

Four species had 30 or fewer individual site records in the ANHAT database (
Table 293). Of those species, no species is listed as threatened. There are too few
species and too little information available to confidently determine any patterns in
the categories developed in the analyses of this family. Exclusion of these poorly
recorded species eliminates 99 records.

Removal of records for the poorly recorded species leaves 4394 records in ANHAT
for 25 species (and subspecies). The mean number of records per species for species
with greater than 30 records was 176, with a mean of 35% of records in the NRS.
Five species of Menyanthaceae had 45% or greater of individual site records located
within PAs (Table 295). Of those five species, one species is classified as
endangered. No species has more than 70% of its records located within PAs. No
pattern can be seen in the location of these species or their range sizes.
