Abstract
Abstract A new species endemic to Hawai‘i Island, Tetramolopium stemmermanniae, is described and illustrated. Molecular and morphological evidence support T. stemmermanniae as being distinct from T.arenarium var. arenarium, T.consanguineum ssp. leptophyllum, and T.humile ssp. humile, which occur at Pōhakuloa Training Area, Hawai‘i Island. Tetramolopium stemmermanniae shares an upright and multibranched habit with T.arenarium var. arenarium and T.consanguineum ssp. leptophyllum but differs in the number and color of ray and disc flowers, and in having an open, paniculate inflorescence. We provide a description of the new taxon, include a key to the Tetramolopium species of Hawai‘i, and a brief description of the habitat where the newly described species occurs.
摘要/ Abstract摘要:报道了夏威夷岛特有的一新种——四色鸦片(Tetramolopium stemmermanniae)。分子和形态学证据表明，该植物不同于arenarium var. arenarium, T. conanguineum ssp.。leptopphylum，和T.humile。在夏威夷岛Pōhakuloa训练区进行。四足鸦片与沙蚕、沙蚕具有直立多分枝习性。薄叶属，但在射线和盘状花的数量和颜色上不同，并且有一个开放的，圆锥状的花序。我们提供了一个新的分类单元的描述，包括夏威夷的四足鸦片物种的一个关键，并简要描述了新描述的物种发生的栖息地。
