Abstract The dioecious seagrass species Halophila stipulacea reproduces mainly through fast clonal growth, underlying its invasive behavior. Here, we provide morphological evidence to show that the first findings of fruits in the Caribbean were misidentified. Consequently, H. stipulacea reproduction is likely still only asexual in the Caribbean. Therefore, we introduce an identification key of H. stipulacea reproductive structures to encourage careful identification and quantification throughout its invasive range. Until large-scale seed production in invaded habitats is reported, the apparent low rate of sexual reproduction needs to be considered in current studies investigating the invasion capacity of this species.

侵入性嗜盐菌有性繁殖的不确定证据：鼓励在整个侵入范围内调查花卉和果实生产的新实地指南

摘要 雌雄异株海草物种 Halophila stipulacea 主要通过快速克隆生长繁殖，这是其入侵行为的基础。在这里，我们提供了形态学证据，以表明加勒比地区水果的最初发现是错误的。因此，H. stipulacea 的繁殖可能在加勒比地区仍然只是无性繁殖。因此，我们引入了针叶树生殖结构的识别密钥，以鼓励在其侵入范围内仔细识别和量化。在报告入侵栖息地的大规模种子生产之前，在调查该物种入侵能力的当前研究中需要考虑明显低的有性繁殖率。
