Sphagnum such gemmae. Peat moss can be distinguished from other moss species by its unique branch clusters. The plant and stem color, the shape of the branch and stem leaves, and the shape of the green cells are all characteristics used to identify peat moss to species. "Sphagnum" taxonomy has been very contentious since the early 1900s; most species require microscopic dissection to be identified. In the field, most "Sphagnum" species can be identified to one of four major sections of the genus—classification and descriptions follow Andrus 2007 (Flora North America): The reciprocal monophyly of these sections and two other minor
Aspasia (plant) active growth. They need at least 75% of humidity and good ventilation all the time. Moderate weekly fertilizing with a balanced formula is beneficial during active growth. They may be potted in a compost of half-chopped Sphagnum, vegetable fiber, and some medium-sized lumps of charcoal, or mounted on plaques of vegetable fiber, however, if mounted, they will need more frequent waterings. The genus "Aspasia" was proposed by John Lindley in 1833 when he described its type species, "Aspasia epidendroides". The name of the genus is a reference to Aspasia of Miletus a friend of Pericles. Its original description is very
