Royal Botanical Gardens Herbarium (HAM)

The Royal Botanical Gardens Herbarium (HAM) houses 62,000 accessioned vascular plant specimens from 191 families. After its founding in 1950, approximately 9000 specimens were collected by Ecologist Aleksander Tamsalu over the course of a few years. The collection has a focus on the local floras of Burlington and Hamilton, Ontario, with approximately half of the collection from specifically within the Royal Botanical Gardens' Nature Sanctuaries and to a smaller degree, its cultivated areas. Notable specimens include nomenclatural standards of Syringa and type specimens of the Gentianaceae as described by Dr. James Pringle. HAM is the only Canadian herbarium to accept nomenclatural standards. HAM incorporated the herbarium of McMaster University, Hamilton College (MCM) in 1966. Other notable, historical collections include those of Christian Ramsay Brown (Lady Dalhousie) and of the Hamilton Association for the Advancement of Literature, Science and Art. HAM continues to accession an average of 385 specimens yearly.

皇家植物园标本馆（Royal Botanical Gardens Herbarium，缩写HAM）馆藏62000份已正式登录归档的维管植物标本，涵盖191个科。该馆于1950年成立后，生态学家亚历山大·塔姆萨卢（Aleksander Tamsalu）在数年时间内采集了约9000份标本。本馆藏重点覆盖加拿大安大略省伯灵顿与汉密尔顿地区的本土植物区系，约半数标本采自皇家植物园自然保护区内，另有小部分来自园区的栽培区域。其代表性馆藏包括丁香属（Syringa）的命名标准标本，以及由詹姆斯·普林格尔博士（James Pringle）描述的龙胆科（Gentianaceae）模式标本。HAM是加拿大境内唯一可接收命名标准标本的标本馆。1966年，HAM并入了麦克马斯特大学汉密尔顿学院标本馆（McMaster University, Hamilton College，缩写MCM）的馆藏。其他重要历史馆藏还包括克里斯蒂安·拉姆齐·布朗（Christian Ramsay Brown，即达尔豪西女爵Lady Dalhousie）的藏品，以及汉密尔顿文学、科学与艺术促进协会的标本馆藏。目前，HAM仍以年均385份的速度新增登录标本。
