Herbaria and natural history collections (NHC) are critical to the practice of taxonomy and have potential to serve as sources of data for biodiversity and conservation. They are the repositories of vital reference specimens, enabling species to be studied and their distribution in space and time to be documented and analysed, as well as enabling the development of hypotheses about species relationships. The herbarium of the Museum of New Zealand Te Papa Tongarewa (WELT) contains scientifically and historically significant marine macroalgal collections, including type specimens, primarily of New Zealand species, as well as valuable exsiccatae from New Zealand and Australia. The herbarium was initiated in 1865 with the establishment of the Colonial Museum and is the only herbarium in New Zealand where there has been consistent expert taxonomic attention to the macroalgae over the past 50 years. We examined 19,422 records of marine macroalgae from around New Zealand collected over the past 164 years housed in WELT, assessing the records in terms of their spatial and temporal coverage as well as their uniqueness and abundance. The data provided an opportunity to review the state of knowledge of the New Zealand macroalgal flora reflected in the collections at WELT, to examine how knowledge of the macroalgal flora has been built over time in terms of the number of collections and the number of species recognised, and identify where there are gaps in the current collections as far as numbers of specimens per taxon, as well as with respect to geographical and seasonal coverage.
植物标本馆和自然历史藏品（NHC）对于分类学实践至关重要，并且有潜力作为生物多样性和保护数据的来源。它们是重要参考标本的储存库，使人们能够研究物种，记录和分析其在空间和时间上的分布，还能提出有关物种关系的假设。新西兰蒂帕帕国家博物馆（Te Papa Tongarewa）的植物标本馆（WELT）收藏了具有科学和历史意义的海洋大型藻类标本，包括模式标本，主要是新西兰物种的标本，以及来自新西兰和澳大利亚的珍贵干制标本。该植物标本馆始建于1865年，随着殖民地博物馆的建立而设立，是新西兰唯一在过去50年里一直有专业分类学家持续关注大型藻类的植物标本馆。我们检查了WELT收藏的过去164年间在新西兰各地采集的19422份海洋大型藻类记录，从空间和时间覆盖范围以及独特性和丰富度方面评估这些记录。这些数据提供了一个机会，来审视WELT收藏中所反映的新西兰大型藻类植物区系的知识状况，研究大型藻类植物区系的知识是如何随着时间推移，根据采集数量和所识别的物种数量而积累起来，并确定就每个分类单元的标本数量以及地理和季节覆盖范围而言，当前收藏中的空白之处。
