to be extant. This is the first record of the occurrence of Carex tribuloides var. sangamonensis in
Leavenworth County and the first time the taxon has been documented in the northeastern part of
the state.
A large population of Hydrophyllum appendiculatum Michx. (Hydrophyllaceae; notchbract
waterleaf) was reported by Freeman et al. (1997) from Maple-Basswood forest at the base of the
steep bluff that parallels the Missouri River floodplain in the north-central part of FLMR, and the
species was reported to be scattered to locally common in floodplain forests along the Missouri
River. Observations during the 2003 field season confirmed that this species is common in wetmesic
sites in Maple-Basswood Forest on the installation (Table 4.7, occurrence 1; Figure 4.10),
where it is often found with its more common congener, Hydrophyllum virginianum. A smaller
population was observed in high-quality Pecan-Hackberry Floodplain Forest (Table 4.7,
occurrence 2). This species is known in Kansas from 21 recent and historic collections made in
six counties in the northeastern part of the state. Of these, 11 collections in five counties were
made subsequent to 1975 and the populations they represent are considered likely to be extant.
A single individual of Hypericum ascyron L. (Clusiaceae; giant St. John’s-wort) was discovered
late in the 2003 field season near the edge of the Missouri River in disturbed Cottonwood-
Sycamore Floodplain Forest (Figure 4.11). Subsequent attempts to locate additional individuals
of this species in similar habitat proved unsuccessful and the size and quality of this population is
unknown. Prior to its discovery on FLMR, this species was known in Kansas only from a single
historical collection made in 1947 in Doniphan County.
Lipocarpha micrantha (Vahl) G.C. Tucker (Cyperaceae; small-flower dwarf-bulrush) was first
collected on FLMR during the 1995–1996 field seasons. This species was not included among
the state-rare species discussed by Freeman et al. (1997), but subsequent research has shown
small-flower dwarf-bulrush to be rare in Kansas. On FLMR, this annual graminoid is locally
abundant with other members of the sedge family in the Riverine Sand Flats-Bars Sparse
Vegetation community along the Missouri River (Figure 4.12). This species is known from 12
recent and historic collections from nine counties throughout the eastern half of the state. Of
these, seven collections in five counties were made subsequent to 1979 and the populations they
represent are considered likely to be extant.
Two small subpopulations comprising widely scattered individuals of the perennial herb
Lithospermum latifolium Michx. (Boraginaceae; American gromwell) were discovered in mesic
draws in White oak-Shagbark hickory Forest during the 1995–1996 field seasons. In Kansas, this
species is known from eight recent and historic reports or collections from 5 counties in
northeastern part of the state. Of these, three collections in three counties were made subsequent
to 1979 and the populations they represent are considered likely to be extant. Efforts to relocate
the population on FLMR during the 2003 field season were unsuccessful. However, given the
longevity of individuals of this species, additional surveys may reveal that plants have persisted
on the installation.
Populations of Osmorhiza claytonii (Michx.) C.B. Clarke (Apiaceae; hairy sweet-cicely) were
reported by Freeman et al. (1997) as occurring throughout most of the White oak-Shagbark
