Chromosome numbers of the aggregate species Triglochin maritimum range from the diploid number 2n = 12 to the 24-ploid number 2n = 144. It is shown that the typical Linnaean species from northern Europe is octoploid with 2n = 48 chromosomes, and the same number is typical of the distinct species concinnum from the Pacific Coast of North America. Lower numbers are known from southern Europe, whereas the 20-ploid number has been determined from the Japanese taxon T. asiaticum here elevated to the species level. The segregate from the western plains of North America is shown to be a 16-ploid taxon which has been regarded as a variety of T. maritimum or T. concinnum by various authors; it is here raised to specific rank as T. debile. The eastern North American plant, which may be identical with some southern and western populations not yet studied cytologically, has 2n = 144 chromosomes and is found to be identical with the long ignored species T. elatum. The importance of exact identification and segregation of types differing in chromosome number for all exact geobotanical studies is emphasized.

A new species, Triglochin gaspense Lieth \& D. L\öve, is described from a salt marsh between Barachois-Ouest and Coin-du-Banc, Gasp\é Peninsula, Quebec, Canada. It is distributed in Quebec, the Canadian Maritime Provinces, and Newfoundland, as well as in at least the northern part of the state of Maine, U.S.A. It is well differentiated from the other American species of the Triglochin maritimum complex, to which it belongs, morphologically (5-20 cm tall, leaves overtopping the short, few-flowered spike), cytologically (2n = 96 chromosomes), and ecologically (confined to the tidal zone of the Atlantic coast below the high-water mark). The type specimen of the new species is preserved in the Marie-Victoria Herbarium, Universit\é of Montr\éal.
