Question: Between the Cymbidium and the Romulea genus plants, which was described as a genus in 1772?
Context: Draparnaldia is a genus of freshwater green algae, in the family Chaetophoraceae.  Draparnaldia are uniseriate; each filament is composed of a chain of cells arranged in one row.  Chloroplasts appear as a band within the center of each cell.  The length of the main axis cells are generally the same, regardless of whether or not they bear branches.  These side branches are divided extensively into terminal hairs.  The entire plant is enveloped in loose, slippery mucilage.  "Draparnaldia" is a cosmopolitan genus with wide distribution and it is usually found in cold aerated waters.They are either attached to sand or grow epiphytically on other aquatic plants.  "Draparnaldia" can be seen growing in clear streams trailing on stones and boulders .  Herman S. Forest of The Southern Appalachian Botanical Club has stated that while not common, it is present frequently enough to be recorded in almost all local flora lists of green algae that have been compiled.  A multitude of species are present in Lake Baikal, Siberia and have been described by Meyer and Jasnitzky.  It is interesting to note that a species of the genus had been placed and described in the Linnean Herbarium as Conferva Mutabilis Roth in 1797.  Nowadays Conferva is no longer used and the species is described as Draparnaldia mutabilis (Roth) Bory.  Bory is added in honour of the researcher of the same name, based on whose description the genus was separated from similar appearing forms.  Bory is accredited with the establishment of the genus. Hessea is a genus of bulb-forming plants in the Amaryllis family native to Namibia and South Africa.  The genus name commemorates C. H. F. Hesse (1772–1832), who resided in Cape Town from 1800 to 1817. Thecostele is a monotypic genus of orchids (family Orchidaceae) and of subtribe Cymbidiinae.  The only species in the genus is Thecostele alata, first described as "Cymbidium alatum" by the Scottish botanist William Roxburgh in 1832.  It was transferred to the genus "Thecostele" in 1874 by the English botanist Charles Samuel Pollock Parish and the German botanist Heinrich Gustav Reichenbach.  It is native to tropical Asia and is found in northeastern India, Bangladesh, Myanmar, Thailand, Cambodia, Laos, Vietnam, Malaysia, Indonesia, and the Philippines.  Two species formerly recognized in this genus ("T. secunda" and "T. maingayi") were transferred to the new genus "Thecopus" by the Danish botanist Gunnar Seidenfaden in 1983, a decision supported by the number of pollinia and shape of the column. Restio is the name of a group of plants within the Restionaceae described as a genus in 1772. Oeceoclades calcarata is a terrestrial orchid species in the genus "Oeceoclades" that is endemic to Madagascar.  It was first described by the British botanist Robert Allen Rolfe in 1905 as "Eulophia paniculata".  The German botanist Rudolf Schlechter later described this species as "Cymbidium calcaratum" in 1915 and then transferred his own taxon to the genus "Eulophia" (as "E. calcarata") in 1925.  When Leslie Andrew Garay and Peter Taylor revised the genus "Oeceoclades" in 1976, they transferred this species to the expanded "Oeceoclades" as "O. calcarata" because even though "Eulophia paniculata" was the older name and thus had priority, there had already been an earlier species named "Oeceoclades paniculata" (so named by John Lindley and now recognized as a species in the genus "Robiquetia") that prevented using that specific epithet. Cássio van den Berg (born 1971) is a Brazilian botanist.  He is noted for work in orchid classification and evolution, especially great changes in the generic circumscriptions of ornamental orchids in the genus "Cattleya", based on DNA studies for the subtribe Laeliinae.  Based on this studies, he proposed a fusion of the genera "Cattleya", "Laelia" (only Brazilian species), and "Sophronitis".  In Laeliinae, the studies pointed out to the separation of subtribe Ponerinae, and the transfer of "Dilomilis" and "Neocogniauxia" to Pleurothallidinae.  He also worked in the taxonomy of other orchid genera, such as "Acianthera", "Baptistonia", "Bulbophyllum", "Cymbidium", "Encyclia", "Galeandra", "Isabelia" and "Pleione".  In 2004, he described a new genus of Laeliinae, "Adamantinia" Van den Berg & C.N.Gonç.  Currently he is full professor and curator of the Laboratory of Plant Molecular Systematics. Lamprocephalus is a genus plants in the groundsel tribe within the sunflower family. Cymbidium , or boat orchid, is a genus of 52 evergreen species in the orchid family Orchidaceae.  The new Latin genus name is derived from the Latin "cymba" meaning boat.  Its first known use was in 1815. Romulea is a genus of flowering plants in the iris family, first described as a genus in 1772.  It is distributed in Europe, the Mediterranean, the Arabian Peninsula, and Africa. Mycena galericulata is a mushroom species commonly known as the common bonnet, the toque mycena, or the rosy-gill fairy helmet.  The type species of the genus "Mycena" was first described scientifically in 1772, but was not considered a "Mycena" until 1821.  It is quite variable in color, size, and shape, which makes it somewhat difficult to reliably identify in the field.  The mushrooms have caps with distinct radial grooves, particularly at the margin.  The cap's color varies from grayish brown to dark brown and the shape ranges from bell-like to bluntly conical to flattened with an umbo.  The stem is hollow, white, tough and thin, without a ring and often roots deeply into the wood on which it grows.  The gills are white to grayish or even pinkish when mature and are connected by distinct cross-veins.  The caps can reach 4 cm in diameter, and have a mealy odor and taste.  The spore print is white and the gills are pink at maturity, which can lead to possible confusion with species of the "Pluteus" genus.  "M. galericulata" mushrooms grow mostly in clusters on the well-decayed stumps of deciduous and coniferous trees from spring to autumn.  The species can generally be considered inedible.  It is common and widespread in the entire temperate zone of the Northern Hemisphere, but it has also been reported from Africa.
Answer: Romulea
