"It prefers the seclusion of almost inaccessible stream beds, where it flourishes on little hummocks just above water level". (Edgerton, 1936 Natural History Society of Maryland Bulletin). "Swamps and bogs" (Brown & Brown 1984). Sphagnous wet places.

Frequency: "Rare and local" (Gray 1867). No Maryland stations known to Shreve et al 1910 - see p. 86,87. Only one Md. station (A. A. Co. 1952) noted by Broome et al Dec. 1979. In 1990 two stations were extant in Cecil Co., and two in upper A. A. Co.

Heritage Rating: 1988: A2 (Nationally threatened, in danger of extinction rangewide). 1991: Endangered; Federal LT (Threatened). 2001: S2 (State rare) Endangered.

Records:

(1) In a floodplain meadow near "Forest Home" (Plitt 5/2/03, 4/29/05). This was probably the one Md. station (A. A. Co. 1952) noted by Broome et al (Dec. 1979). Extant in 1958 (See Haven Kolb, Maryland Naturalist 1958). Photographed for Maryland Naturalist by Charles Stine in 1964, according to Gene Cooley. See Reveal & Broome 1982: "The one Anne Arundel site where the plant was found in 1952 (Worthley, pers. comm., 1979, 1981; Kolb, pers. comm., 1979) has since been developed and the habitat destroyed." Rucker believes he located the site on Marley Creek Branch in March 1990. Stormwater runoff from apartment buildings has greatly eroded the upstream ravine, and a large alluvial fan has covered the floodplain meadow. No plants were seen in the dense, very wet shrub-swamp downstream. Also see Sipple 1999, pp.340-342.

(2) A station found "in the swamp near Stony Run below Elkridge" by Plitt in 1904 (See Fessenden, Wildflower, July 1955, p.53) is thought to be the one relocated by Wayne A. Klockner about 1984. It is in a sphagnous lowland woods of pitch pine, ash, and red maple on BWI Airport property. Clearing of the site by the BWI authorities was narrowly avoided.

(3) Stony Creek: Noted by C. C. Plitt, 1906 (Sipple 1999, p.345). Rediscovered by Nancy Kelly in 1988, while surveying the property for a new residential development. The site is a wooded sphagnous lowland of red maple and pitch pine on the watershed of Stony Creek, off Solley Road. This station has 200 or more plants along a tiny stream. Extensive bulldozing of the adjoining upland woods was underway on 4/12/90.

(4) At the headwaters of Stony Run in Severn, a small privately-owned station was discovered ca. 1991. Near Cedar Drive, in Severn Ridge, it was reported (The Capital, August 1993) to be threatened by a proposed sewer-line project.

(5) Three small patches near Waterford Branch above Elvaton Road
