ZANNICHELLIACEAE 950
broadened sheath of Najas. Also, the seeds are flattened in Zannichellia, and toothed down one side; Najas has a cylindric or
elliptic fruit. Zannichellia has longer leaves (3-10 cm long) than Najas (< 4 cm long).
Zannichellia palustris Linnaeus, Horned Pondweed. Cp (NC, VA), Mt (VA), {GA}: fresh or brackish water; common.
February-October. The species occurs throughout much of the world. [= RAB, C, FNA, G, GW, K, S, W, Z; > Z. palustris var.
major (Hartman) W.D.J. Koch – F; > Z. palustris var. palustris – F]
ZOSTERACEAE Dumortier 1829 (Eelgrass Family)
A family of 3 genera and about 18 species, nearly cosmopolitan in distribution. References: Haynes in FNA (2000); Kuo &
McComb in Kubitzki (1998b).
Zostera Linnaeus 1753 (Eelgrass)
A genus of about 12 species, aquatic herbs, of nearly cosmopolitan distribution. References: Haynes in FNA (2000); Crow &
Hellquist (2000)=Y; Kuo & McComb in Kubitzki (1998b); Green & Short=Z.
Zostera marina Linnaeus var. stenophylla Ascherson & Graebner, Eelgrass. Cp (NC, VA): estuarine waters; common.
February-March. The species occurs in Eurasia and North America. Var. stenophylla is North American, and ranges south along
the Atlantic coast to NC and allegedly to FL (though reports from that state are apparently not substantiated and may be based on
misidentification of other aquatics). [= F, G, Y; < Z. marina – RAB, C, FNA, K, S, Z]
