NHESP is responsible for the conservation and protection of hundreds of species that are not hunted, fished, trapped, or commercially harvested in the state. The Program's highest priority is protecting the 176 species of vertebrate and invertebrate animals and 259 species of native plants that are officially listed as Endangered, Threatened or of Special Concern in Massachusetts. Endangered species conservation in Massachusetts depends on you! A major source of funding for the protection of rare and endangered species comes from voluntary donations on state income tax forms.

It is suggested that Osmunda intermedia is an intrasub- generic hybrid (O. japonica of subgenus Osmunda ϫ O. lancea of subgenus Osmunda), O. ruggii is an intersubgeneric hybrid (O. regalis of subgenus Osmunda ϫ O. claytoniana of subgenus Clay- tosmunda), O. nipponica is an intersubgeneric hybrid (O. japonica ϫ O. claytoniana of subgenus Claytosmunda), and O. midlei is an intersubgeneric hybrid (O. japonica ϫ O. angustifolia or O. vachellii of subgenus Plenasium). Among the four, O. intermedia is the most widely distributed and can reproduce in culture, suggesting that it can reproduce to some extent in nature.

  • Wool-Grass – Mannagrass Mixed Shrub Marsh
    Wool-grass – Mannagrass Mixed Shrub Marsh System: Palustrine Subsystem: Herbaceous PA Ecological Group(s): Vernal Pool Global Rank: GNR State Rank: S4 General Description The Wool-grass – mannagrass mixed shrub marsh pool occurs in seasonally to somewhat permanently inundated depressions throughout Pennsylvania. The type can be described as a seasonally flooded, herbaceous swamp with well defined boundaries; some pools of this type exhibit somewhat poorly defined boundaries. The surrounding plant community varies with region, soils, and geology. The pools are generally deeper than those of the Rice cutgrass – bulrush marsh pool and may not dry completely over the summer months. This community is characterized as an open, seasonally to permanently flooded depression, dominated by herbaceous and shrubby species; wool-grass (Scirpus cyperinus) is usually dominant. Common co- dominant and associate species include floating mannagrass (Glyceria septentrionalis), rattlesnake mannagrass (Glyceria canadensis), rice cutgrass (Leersia oryzoides), pale meadowgrass (Torreyochloa pallida), sedges (e.g. Carex crinita, C. lurida, C. lupulina, C. vesicaria, C. folliculata), three-way sedge (Dulichium arundinaceum), mild water-pepper (Persicaria hydropiperoides), marsh-purslane (Ludwigia palustris), marsh St. Johns-wort (Triadenum fraseri). The federally endangered species, northeastern bulrush (Scirpus ancistrochaetus), is also found in this type. Shrubs include hardhack (Spiraea tomentosa), meadow-sweet (S. alba), northern arrow-wood (Viburnum recognitum), highbush blueberry (Vaccinium corymbosum), and buttonbush (Cephalanthus occidentalis). Canopy trees, which are limited to the pool margins, most often include white oak (Quercus alba), sourgum (Nyssa sylvatica), and red maple (Acer rubrum). Rank Justification Uncommon but not rare; some cause for long-term concern due to declines or other factors. Identification Open, seasonally flooded depression, dominated by herbaceous plants, usually graminoids.

  • Rice Cutgrass – Bulrush Vernal Pool
    Rice Cutgrass – Bulrush Vernal Pool System: Palustrine Subsystem: Herbaceous PA Ecological Group(s): Vernal Pool Global Rank: GNR, G1 State Rank: S2? General Description This community is characterized as an open, seasonally flooded, mixed-herbaceous wetland meadow with defined basin boundaries and usually occurs within dry, oak-dominated forests with open canopies. Common dominant species include pale meadowgrass (Torreyochloa pallida), mannagrass (Glyceria acutiflora), rattlesnake mannagrass (Glyceria canadensis), three-way sedge (Dulichium arundinaceum), Canada bluejoint (Calamagrostis canadensis), rice cutgrass (Leersia oryzoides), sedges (e.g. Carex tribuloides, C. lurida, C. gynandra, C. vesicaria, C. folliculata), dotted smartweed (Persicaria punctata), marsh St. Johns-wort (Triadenum fraseri), royal fern (Osmunda regalis), needle spike-rush (Eleocharis acicularis), and white beak-rush (Rhynchospora alba). The federally endangered species, northeastern bulrush (Scirpus ancistrochaetus), is also found in this type, and can sometimes comprise a significant area within the pool. The invasive low smartweed (Persicaria longiseta) was present within this type in some pools and stiltgrass (Microstegium vimineum), can form dense patches on the edges of the pools. Shrubs such as winterberry (Ilex verticillata) and swamp dewberry (Rubus hispidus) are present, but never dominant and canopy trees most often include white oak (Quercus alba), sourgum (Nyssa sylvatica), and red maple (Acer rubrum). The pools may also contain a substantial bryophyte

  • Fern Classification
    16 Fern classification ALAN R. SMITH, KATHLEEN M. PRYER, ERIC SCHUETTPELZ, PETRA KORALL, HARALD SCHNEIDER, AND PAUL G. WOLF 16.1 Introduction and historical summary / Over the past 70 years, many fern classifications, nearly all based on morphology, most explicitly or implicitly phylogenetic, have been proposed. The most complete and commonly used classifications, some intended primar• ily as herbarium (filing) schemes, are summarized in Table 16.1, and include: Christensen (1938), Copeland (1947), Holttum (1947, 1949), Nayar (1970), Bierhorst (1971), Crabbe et al. (1975), Pichi Sermolli (1977), Ching (1978), Tryon and Tryon (1982), Kramer (in Kubitzki, 1990), Hennipman (1996), and Stevenson and Loconte (1996). Other classifications or trees implying relationships, some with a regional focus, include Bower (1926), Ching (1940), Dickason (1946), Wagner (1969), Tagawa and Iwatsuki (1972), Holttum (1973), and Mickel (1974). Tryon (1952) and Pichi Sermolli (1973) reviewed and reproduced many of these and still earlier classifica• tions, and Pichi Sermolli (1970, 1981, 1982, 1986) also summarized information on family names of ferns. Smith (1996) provided a summary and discussion of recent classifications. With the advent of cladistic methods and molecular sequencing techniques, there has been an increased interest in classifications reflecting evolutionary relationships. Phylogenetic studies robustly support a basal dichotomy within vascular plants, separating the lycophytes (less than 1 % of extant vascular plants) from the euphyllophytes (Figure 16.l; Raubeson and Jansen, 1992, Kenrick and Crane, 1997; Pryer et al., 2001a, 2004a, 2004b; Qiu et al., 2006). Living euphyl• lophytes, in turn, comprise two major clades: spermatophytes (seed plants), which are in excess of 260 000 species (Thorne, 2002; Scotland and Wortley, Biology and Evolution of Ferns and Lycopliytes, ed.

Our results confirm those from earlier anatomical and single-gene (rbcL) studies that suggested Osmunda s.l. is paraphyletic. Osmunda cinnamomea is sister to the remainder of Osmundaceae (Leptopteris, Todea, and Osmunda s.s.). We support the recognition of a monotypic fourth genus, Osmundastrum, to reflect these results. We also resolve subgeneric relationships within Osmunda s.s. and find that subg. Claytosmunda is strongly supported as sister to the rest of Osmunda. A stable, well-supported classification for extant Osmundaceae is proposed, along with a key to all genera and subgenera. Keywords—ferns, Osmunda, Osmundaceae, Osmundastrum, paraphyly, plastid DNA.
