Systematic implications of isozymes in Halophila section Halophila
Aquatic Botany, 1980Isozymes in seven enzyme systems were studied by gel electrophoresis for clues to the taxonomic relationships of species in Halophila section Halophila. As presented in den Hartog's (1970) original treatment, the section included four species, H. ovalis (R.Br.) Hook. f. with four subspecies (ssp. bullosa (Setchell) den Hartog, ssp.

REMARKS ON HALOPHILA (HYDROCHARITACEAE)
TAXON, 1973SummaryTaxonomic and nomenclatural notes on Halophila, supplemental to den Hartog's monograph, clarifying publication of generic synonym Lemnopsis; establishing H. minor as correct name for what has been called H. ovata; reducing H. ovalis var. bullosa and H. madagascariensis to H. minor; and reinstating H.

The threatened seagrass Halophila johnsonii Eiseman coexists subtidally with H. decipiens Ostenfeld in southeastern Florida, but only H. johnsonii also oc- curs intertidally. Pulse amplitude modulated fluorome- try and fiber-optic spectrometry were used to investigate the photobiology of two populations of H. johnsonii and H. decipiens in an attempt to

Abstract Along the coastal lagoons of southeast Florida, Halophila johnsonii and Halophila decipiens co-occur subtidally, but only H. johnsonii occurs intertidally. Photosynthetic tolerances to desiccation in light and dark conditions were compared between H. johnsonii and H.

a b s t r a c t In this study, flavonoid localization, content and total antioxidant capacity in leaves of subtidal Halophila decipiens were compared to intertidal and subtidal Halophila johnsonii. H. johnsonii leaves had significantly higher flavonoid content (3.5 and 3.8 nmol quercetin equivalent mm −2 leaf for intertidal and subtidal H.

Flavones and flavone glycosides from Halophila johnsonii
Phytochemistry, 2008Halophila johnsonii Eiseman is a shallow-water marine angiosperm which contains UV-absorbing metabolites. Studies on methanol extracts of H. johnsonii by means of HPLC-UV, NMR, HPLC-MS resulted in isolation and identification of seven previously unknown flavone glycosides: 5,6,7,3',4',5'-hexahydroxyflavone-7-O-beta-glucopyranoside (1), 5,6,7,3',4',5 ...

The growth dynamics of Halophila hawaiiana
Aquatic Botany, 1986Abstract A functional growth model was developed for Halophila hawaiiana Doty and Stone, based on its regular plastochrone interval, and the relationship between leaf area and plant biomass. The model allows estimates of biomass, productivity and turnover from easily collected field samples. From these samples, the number of actively growing apical

Megagametogenesis, the development of a megaspore into an embryo sac, has been identified in the seagrass Halophila johnsonii, a threatened species with no known sexual reproduction or seeds. Megagametogenesis in H. johnsonii was compared with megagametophyte development in Halophila decipiens, a related species known to readily produce viable seeds ...
