摘要

摘要/ Abstract摘要:叶间交叉棘藓(Leucostele) atacamensis亚科的一种单生植物。在智利安第斯山脉的阿塔卡马盐沼地区，在亲本种主要异域居群的接触区观察到atacamensis × Echinopsis (Soehrensia) formosa。该植物的性状介于亲本之间。发现它是不育的，尽管看起来正常的花药(有丰富的花粉)和柱头。此外，人们还发现了一种典型的黄花阿塔卡camensis，但尚不清楚这是否仅仅是一种花色变异，还是可能涉及杂交。

A Putative Intercladal Echinopsis s.l. (Cactaceae) Hybrid from Andean Chile

Abstract: A solitary plant of the putative intercladal cross Echinopsis (Leucostele) atacamensis subsp. atacamensis × Echinopsis (Soehrensia) formosa was observed in the contact zone of the mostly allopatric populations of the parent species in the Salar de Atacama region in the Chilean Andes. The plant is intermediate between the parents in its characters. It was found to be sterile, despite normal-looking anthers (with abundant pollen) and stigma. In addition, an apparently typical individual of E. atacamensis with yellow flowers has been found, but it remains unknown whether this is merely a flower colour variant, or whether hybridization could be involved.
