A specimen collected in southern Tibet in 1928, hitherto identified only as “Arenanu sp.”, is found to represent a new species of the subgenus Odontostemma. The new species resembles A. littledalei, the species that forms the basis of the monotypic genus Gooringia, characterized by a dwarf habit, a tetramerous perianth and only two or three stamens. Several other species of Arenaria subgenus Odontostemma resemble A. littledalei in habit and one (A. saginoides) is tetramerous, but hitherto none has been found with its extremely reduced androecium. The new species has an identical androecium to A. littledalei and its discovery leaves no doubt that Gooringia should not be recognized taxonomically at any rank. The new species is described as A. pharensis McNcill & Majumdar and a table compares its diagnostic features with those of A. littledalei and five other dwarf Arenaria species of sibgrnus Odontostemma from the mountains of Sikkim, Tibet, Yunnan and Tsinghai. |
