"Society ... must take a strong stand for conservation. in a democracy, we cannot expect to have the problems of conservation and wildlife management solved intelligently without an informed public". readers will be forgiven if they think this is a new challenge to Canadians from an expert body that be - lieves the present federal government is on a path of unconscionable suppression of nationally important environmental research and monitoring programs. it is actually a clarion call from the past to the Saskatchewan natural History Society (SnHS - now nature Saskat - chewan) to refocus itself as an advocate of the protection of natural environmental values in western Canada. and far from being a contemporary challenge, it was written in 1956, over half a century ago.

An illustrated key based on morphological, ecological and geographical characteristics is presented for the Isoëtes taxa of the Coastal Plain, Piedmont and the eastern side of the Appalachian Mountains of Alabama, District of Columbia, Delaware, southern Maryland, North Carolina, South Carolina, Florida, Georgia, Mississippi, eastern Louisiana, southeastern Tennessee and eastern Virginia. The key includes 22 species, three additional subspecies/ varieties and nine sterile hybrids. It is primarily intended to serve as an investigative tool to assist field botanists engaged in conservation, floristic and ecological studies in the Southeast. © 2015 American Fern Society. Source


Six populations of Great Plains Ladies'-tresses (Spiranthes magnicamporum Sheviak) have recently been discovered in three locations east of the lower Great Lakes region of Canada and the United States. The possible occurrence of S. cernua × magnicamporum hybrids was detected at one New York site. These discoveries are from both natural alvar and disturbed meadow and shore sites. The new records suggest that S. magnicamporum occurs more widely than was suspected previously, its presence perhaps masked by its similarity to the common S. cernua (L.) Richard. Eastern occurrences may represent a combination of post-glacial relict populations, responses to climate change, and the results of long-distance dispersal events. These range extensions constitute the most easterly known populations of S. magnicamporum in North America. They also represent new records for New York State (including Jefferson and St. Lawrence Counties) and for the City of Ottawa in Ontario. © 2015 The Canadian Field-Naturalist. Source

The lycophyte Northern Quillwort (Isoetes septentrionalis D. F. Brunton, sp. nov.) is the northern component of the riverbank Quillwort (I. riparia) complex. it is locally abundant in southeastern Ontario and southwestern Quebec and is also widely distributed in the northeastern United States. in Canada, it is largely confined to river and lake shores along post-glacial drainage outlets within the limits of the post-glacial Champlain Sea. it is frequently found in association with other Isoetes, especially Dodge's Quillwort (I. × dodgei A. A. Eaton), its sterile hybrid with Spiny-spored Quillwort (I. echinospora Durieu). the Canadian population of I. septentrionalis appears to be stable. although first proposed at species level over a century ago, the nomenclature of this taxon has remained unresolved. it is clarified in the present study, in which I. canadensis var. robbinsii is lectotypified. © 2015 The Canadian Field-Naturalist.

Two species of Isoëtes (Isoëtaceae) occur in the Kamchatka Peninsula, northern Russian Far East - I. asiatica (Makino) Makino and I. maritima Underw. The distribution and ecology of these species are discussed. A hybrid of these species was found alongside its parental species in south Kamchatka in the shallows of a lake impacted by humans, and it is formally described here as I.Xparatunica D. F. Brunton, Mochalova & A. A. Bobrov. It is the first Isoëtes hybrid discovered in Russia. © 2015 American Fern Society. Source
