黄花蛇（gaern .）Roxb。原产于亚洲和非洲东部，但已作为城市观赏植物引入美洲。本文首次报道了墨西哥东南部自然环境中scevola taccada的存在。在对科苏梅尔岛生物圈保护区（墨西哥金塔纳罗奥州）海岸沙丘进行的植物调查中，发现了几个S. taccada种群，以记录最常见的植物物种。黄花鳞甲被认为是该地区沿海地区的入侵物种。由不同大小的个体组成的种群分布在整个岛屿，这一事实表明了它的入侵性。此外，它们似乎属于不同的世代，因为我们发现了不同大小的个体，有和没有花朵和果实。我们的观察表明，scevola taccada种群可能处于扩张过程中。需要进一步研究以了解对本地植物群的潜在影响。
Scaevola taccada (Gaertn.) Roxb. is native of Asia and eastern Africa but has been introduced into the Americas as an ornamental urban plant. This paper reports, for the first time, the presence of Scaevola taccada in natural environments from southeastern Mexico. Several populations of S. taccada were identified during a botanical survey of the coastal dunes of the Cozumel Island Biosphere Reserve (State of Quintana Roo, Mexico) aimed at recording the most common plant species. Scaevola taccada is considered as an invasive species of coastal areas in this region. Evidence of its invasiveness is suggested by the fact that populations consisting of individuals of different size classes are found distributed throughout the island. Furthermore, they appear to belong to different generations since we found individuals of different sizes and with and without flowers and fruits. Our observations suggest that the population of Scaevola taccada can be in a process of expansion. Further studies are necessary to understand the potential effect on the native flora.
