Phytochemistry, 1968
Abstract The existence of lignin in Sphagnum moss has been investigated. A vibratory ball milling technique gave a low yield (0·9 per cent) of a presumed lignin. This substance was low in methoxyl, aromatic hydrogen and ether oxygen. It gave an acetate containing 36·5 per cent COCH 3 and nitrobenzene oxidation of this acetate gave small amounts of

The ultrastructure of the placenta in Sphagnum
New Phytologist, 1989summaryThe placenta of two Sphagnum species was examined by electron microscopy. In contrast to all mosses so far investigated, neither sporophyte nor gametophyte placental cells of Sphagnum develop wall ingrowths. The sporophyte cells are highly vacuolate and the gametophyte cells close to them degenerate to produce a system of spaces filled with ...

The Bryologist, 1966
Sphagnum pylaesii and S. angermanicum are reported for the first time from Quebec. Their distribution in the maritime provinces of eastern Canada and Newfoundland is similar in spite of their different habitat requirements. Sphagnum pylaesii is able to grow under nearly arctic conditions in northern Labrador although it is a southern species in Europe;

Notes on North American Sphagnum, II
The Bryologist, 1911The Subgenus Inophloea Russow (concluded) S. erythrocalyx collected by Underwood in the vicinity of Cinchona in Jamaica, one of which (no. 16o) was named by Warnstorf S. medium Limpr. and evidently forms the basis of Warnstorf's assignment of this species to Jamaica,' but S. medium Limpr. is not found in the West Indies. The second (no.

Metagenomics and biodiversity of sphagnum bogs
Molecular Biology, 2016Biodiversity of sphagnum bogs is one of the richest and less studied, while these ecosystems are among the top ones in ecological, conservation, and economic value. Recent studies focused on the prokaryotic consortia associated with sphagnum mosses, and revealed the factors that maintain sustainability and productivity of bog ecosystems.
