ETYM Old Eng. mos; akin to AS. meós, Dutch mos, German moos, Old High Germ. mos, mios, Icel. mosi, Dan. mos, Swed. mossa, Russ. mokh, Latin muscus. Related to Muscoid.
(Irregular plural: mosses).
Tiny leafy-stemmed flowerless plants.
Small nonflowering plant of the class Musci (10,000 species), forming with the liverworts and the hornworts the order Bryophyta. The stem of each plant bears rhizoids that anchor it; there are no true roots. Leaves spirally arranged on its lower portion have sexual organs at their tips. Most mosses flourish best in damp conditions where other vegetation is thin.
The peat or bog moss Sphagnum was formerly used for surgical dressings. The smallest moss is the Cape pygmy moss Ephemerum capensi, only slightly larger than a pin head.

(1929-) English race-car driver. Despite being one of the best-known names in British automobile racing, Moss never won the world championship. He was runner-up on four occasions, losing to Juan Manuel Fangio in 1955, 1956, and 1957, and to fellow Briton Mike Hawthorn (1929–1959) in 1958.
In his early days he drove solely for British manufacturers before moving to the Italian firm Maserati, and then to the German Mercedes team, returning once more to British firms such as Vanwall in 1958 and later to Lotus. A bad accident at Goodwood in 1962 ended his career but he maintained contact with the sport and in recent years has taken part in sports-automobile races.
