摘要

摘要2015年7月，在马萨诸塞州富兰克林县温德尔发现了Drosera中间媒介和圆形叶D.的自然杂交，现在称为×eloisiana(以前称为×belezeana)。对叶片长度和宽度的测量，以及叶柄短柔毛、花药颜色和种子特征等特征，证实了这些植物是杂交植物，并形成了区分杂交植物与其亲本分类群的关键基础。在麻省理工学院发现的一个错位的植物标本表明，这个杂交品种是1980年在马萨诸塞州东部收集的，与加拿大新斯科舍省的一个标本进行比较，证实了这个杂交品种来自该省。Drosera ×eloisiana可能比新英格兰及其他地区的文献记载更为广泛，并且可能会有更多的发现。

The Natural Hybrid between Drosera intermedia and Drosera rotundifolia in Massachusetts

ABSTRACT. The natural hybrid between Drosera intermedia and D. rotundifolia, now known as D. ×eloisiana (formerly D. ×belezeana), was discovered in Wendell, Franklin County, Massachusetts, in July 2015. Measurements of leaf blade length and width, along with characteristics such as petiole pubescence, anther color, and seed characteristics, confirm these plants as hybrids and form the basis for a key to differentiate between the hybrid and its parent taxa. Discovery of a misfiled herbarium specimen at MASS revealed that this hybrid was collected in eastern Massachusetts in 1980, and comparisons with a specimen from Nova Scotia, Canada, confirm the hybrid from that province. Drosera ×eloisiana is likely more widespread than documented in New England and beyond, and additional discoveries may follow.
