The Plant List includes a further 10 scientific plant names of infraspecific rank for the genus Halophila.We do not intend The Plant List to be complete for names of infraspecific rank. Asexual Clonal Growth: Similar to grasses on land, seagrass shoots are connected underground by a network of large root-like structures called rhizomes. Halophila ovalis, which occurs in an extensive monospecific bed for future potential refuge for various kinds of marine organisms. #seagrass #Landsat TM #Radiative Transfer Model. Clockwise from upper left: intertidal population growing with Halodule wrightii; typical asymmetric leaf; fruit attached to rhizome; ovules released from fruit; ovary and styles of the female flower. Wetland Status. Morphological analysis demonstrated the Antiguan Halophila to be well within the range of plant characteristics previously described in the literature for H. ovalis, except for leaf width and number of seeds per fruit, and again, not different from H. johnsonii and very closely related to H. ovalis … To measure primary production we selected three meadows (Neil 1, 2, 3) dominated by Halophila ovalis and which could be accessed throughout the year. Plants are dioecious with male and female flowers produced at each leaf node. halophila — , halophilum, halophilus Gk halos, salt; phileo, love. Halophila ovalis is the dominant seagrass growing in both estuaries. Halophila ovalis from Antigua. At deeper depths, turbid water and muddy substrate, leaves of H. ovalis are elongated in … Rhizomes are creeping, branched and fleshy, and roots appear solitary at each node of the rhizome, unbranched and thick with dense soft root hairs. Schult. Plants → Magnoliophyta → Liliopsida → Alismatales → Hydrocharitaceae Juss. The leaves emerge in pairs from these rhizomes.
