“…The flowering specimens of Ruppia megacarpa from East Asia ex hi bited diagnostic characteristics of the species, such as bi den tate leaf tips, four carpels, and a larger fruit size (Mason 1967, Jacobs & Brock 1982, 2009, Zhao & Wu 2008. Some morphological differences were observed in quantitative cha racters between the three East Asian specimens and ho lo type, such as peduncle length and fruit size.…”

“…The three East Asian flowering specimens of Ruppia me ga car pa and the holotype from New Zealand were examined with special reference to reproductive characters and compared with those reported in the protologue and other taxonomic li te ratures (Mason 1967, Jacobs & Brock 1982, 2009). The length of peduncles, pedicels, and leaves of each specimen were measured using the ImageJ software (Abràmoff et al 2004).…”

“…The taxonomic confusion surrounding this group resulted from of its simple morphology, polyploidy, and worldwide dist ri bution, preventing achievement of consensus regarding the infrageneric taxonomy (reviewed in Ito et al 2010). Mo lecular phylogenetic analyses using plastid and nuclear DNA markers have dramatically resolved this issue and pro posed a new classification of three morphologically and ge ne tically distinct species: Ruppia megacarpa R. Mason (1967), R. polycarpa R. Mason (1967), and R. tuberosa Davis & Tom lin son (1974). In addition, a morphologically diverged but genetically clustered species complex, R. maritima L. (1753), has been identified (Ito et al 2010).…”

“…This species was described in New Zealand (Mason 1967) with larger fruits, well-coiled peduncles, branched to zigzag stems, and bi den tate to truncate leaf tips, and believed to be endemic to the southern region of Australasia (Jacobs & Brock 1982, 2009, and thus, not listed in East Asian floras.…”

A B S T R A C TRuppia L. is the only genus in Ruppiaceae that is primarily distributed in brackish water. A previous molecular phylogenetic work revealed that 2 non-flowering Rup pia specimens from Japan and Russia were genetically identical to Ruppia mega car pa R. Mason, a species previously known only from Australasia. To update East Asian flo ras, our study examined flowering specimens of putative R. megacarpa from East Asia, including the localities where the non-flowering specimens originated, and assessed their morphological characters by comparing them with those of the R. megacarpa holotype from New Zealand as well as morphological data ob tained from the protologue and other systematic works. The three East Asian spe cimens exhibited slightly different quantitative morphology compared with the holotype; however, the values were mostly within the species variation. The spe cies distribution was accordingly revised. -единственный род в семействе Ruppiaceae, чьи представители рас про страняются преимущественно в солоноватой воде. Предшеству-ю щие исследования по молекулярной филогении рода показали, что 2 не цве ту щих образца Ruppia из Японии и России были генетически иден-тич ны Ruppia megacarpa -виду, ранее известному только из Австралии. Для уточ нения видового состава рода в Восточной Азии были исследованы об-раз цы цветущих растений предполагаемого вида Р. megacarpa, в том числе собранные в местообитаниях, откуда взяты нецветущие экземпляры, а также был проведен сравнительный анализ их морфологических признаков с го-ло типом Р. megacarpa из Новой Зеландии и с морфологическими данными, при водимыми в протологах других систематических работ. Три образца с Вос точной Азии имеют незначительные количественные отличия в мор-фо логии в сравнении с голотипом, однако, отклонения не выходят за рам-ки внутривидовой изменчивости. Таким образом распределение данного вида существенно уточнено.

The physiography, indigenous vegettion, and total flora are described for 225 km 2 of Tertiary and Cretaceous rocks which form hilly and mountain landscapes extending from sea level to 1245 m above sea level in southern Marlborough. The rocks include hard limestones which produce high perpendicular cliffs. Sixteen vegetation units ranging from lowland mixed hardwood forest and scrub, through upland forests, to subalpine scrub, are described in relation to local climatic gradients, altitude, topography, and parent materials. Differences between vegetation on non-calcareous and calcareous soils are most distinctive on colluvial slopes with skeletal soils. 562 indigenous gymnosperms, lycopods, ferns, and flowering plants are listed, over half the total for north-east South Island. 217 adventive species are listed. Many indigenous taxa are unnamed, but few are confined to the study area. Overall 5% of the flora are calcicoles but only 2.7% strongly so. Appended notes discuss nomenclature and distribution.
