The diversity and richness of the Brazilian flora are documented in herbarium collections. When areas are deforested, but not documented, we lose both flora and the opportunity to know which species occupied those areas. The south-eastern mesoregion of Mato Grosso State, comprising 22 municipalities, has undergone the loss of native vegetation cover, accelerated by the substantial expansion of agribusiness. For an in-depth look at the consequences and the current state of the flora in that mesoregion, we consulted both speciesLink and JABOT databases. More specifically, we carried out a comprehensive study of herbarium collections by municipality and compiled data including scientific name, collection date, collection locality, collector name and observations made during collection. We obtained 5,861 records of angiosperms, ferns and lycophytes of 160 families, 770 genera and 1,792 species. The specimens are deposited in 80 herbaria of which the Herbarium of Universidade Federal de Mato Grosso (UFMT) hosts the largest collection. Rondonópolis was the most sampled municipality, whereas 50% of the municipalities were poorly sampled and one showed no collection records at all. Amongst the species occurring only in Mato Grosso, eleven were collected only in that mesoregion and twenty species were under some degree of threat. Our study recommends increasing collection and identification efforts to enable effective conservation actions and improve richness estimates for the State of Mato Grosso and the Cerrado, in general, before more of the flora is lost to deforestation.
巴西植物群的多样性和丰富性在植物标本馆收藏中得到了记录。当一些地区被砍伐森林，但却没有相关记录时，我们不仅失去了植物群，也失去了了解哪些物种曾占据这些地区的机会。马托格罗索州的东南部中区域包括22个市，由于农业综合企业的大幅扩张，当地原生植被覆盖面积已经减少。为了深入了解该中区域植物群的现状及其所受影响，我们查阅了物种链接（speciesLink）和JABOT数据库。更具体地说，我们对各市的植物标本馆收藏进行了全面研究，并汇总了包括学名、采集日期、采集地点、采集者姓名以及采集时所做观察等数据。我们获得了160科、770属、1792种被子植物、蕨类植物和石松类植物的5861条记录。这些标本保存在80个植物标本馆中，其中马托格罗索联邦大学植物标本馆（UFMT）的收藏量最大。朗多诺波利斯是采样最多的市，而50%的市采样较少，还有一个市没有任何采集记录。在仅分布于马托格罗索州的物种中，有11种仅在该中区域被采集到，20种处于某种程度的威胁之下。我们的研究建议加大采集和鉴定力度，以便在更多植物因森林砍伐而消失之前，能够采取有效的保护行动，并提高对马托格罗索州和塞拉多地区植物丰富度的估计。
