A bush tomato that has evaded classification by solanologists for decades has been identified and is described as a new species belonging to the Australian " group" of the Ord Victoria Plain biogeographic region in the monsoon tropics of the Northern Territory. Although now recognised to be andromonoecious, Martine & McDonnell, exhibits multiple reproductive phenotypes, with solitary perfect flowers, a few staminate flowers or with cymes composed of a basal hermaphrodite and an extended rachis of several to many staminate flowers. When in fruit, the distal rachis may abcise and drop. A member of SolanumsubgenusLeptostemonum, is allied to the Symon species group. Morphometric analyses presented here reveal that differs statistically from all of its closest relatives including , F. Meull., Martine, J.Cantley & L.M.Lacey, A.R.Bean & Albr. and Martine & Frawley in both reproductive and vegetative characters. We present evidence supporting the recognition of as a distinctive entity, a description of the species, representative photographs, a map showing the distribution of members of the species group and a key to the andromonoecious species of the Northern Territory of Australia. This new species is apparently labile in its reproductive expression, lending to its epithet, and is a model for the sort of sexual fluidity that is present throughout the plant kingdom.
一种数十年来一直未被茄科植物学家分类的野生番茄已被识别出来，并被描述为属于北领地季风热带地区奥德维多利亚平原生物地理区域澳大利亚“类群”的一个新物种。尽管现在被认为是雄花两性花同株，但Martine & McDonnell表现出多种生殖表型，有单生完全花、几朵雄花，或有由基部两性花和由几朵到许多朵雄花组成的延长轴的聚伞花序。结果时，远端轴可能会脱落。作为茄属Leptostemonum亚属的一员，它与Symon物种组有亲缘关系。此处进行的形态计量分析表明，它在生殖和营养特征方面在统计学上与所有最亲近的亲属不同，包括F. Meull.、Martine, J.Cantley & L.M.Lacey、A.R.Bean & Albr.以及Martine & Frawley。我们提供了支持将其识别为一个独特实体的证据、该物种的描述、代表性照片、显示该物种组成员分布的地图以及澳大利亚北领地雄花两性花同株茄属物种的检索表。这个新物种在其生殖表达上显然不稳定，这也赋予了它这个种加词，并且它是整个植物界存在的那种性流动性的一个范例。
