Among the 108 alien vascular species currently found in the sub-Antarctic Cerastium fontanum has a wide distribution only seriously rivalled in range by Poa annua.
Species Description
Cerastium fontanum is a stiff-hairy, glandular biennial or perennial, the stems sprawling but the flowering stems erect, 2-4 dm. tall. Leaves of the prostrate stems opposite, crowded, oblanceolate, 10-25 mm. long and 2-5 mm. broad; leaves of the flowering stems opposite, widely spaced, up to 4 cm. long and 15 mm. broad. Flowers several in an open, dichotomously branched inflorescence; sepals 5, 4-7 mm. long, stiff-hairy; petals 5, white, bi-lobed, equaling the sepals; stamens 10; styles 5. The fruit is a capsule, membranous, cylindric, slightly curved, twice as long as the sepals, opening by 10 teeth (Burke Museum of Natural History and Culture 2006).
In the sub-antarctic region Poa annua and Cerastium fontanum are the most widespread introduced species (Walton 1975), but few data on their reproductive capacity in this biome are available (Frenot & Gloaguen 1994).
