The botanical legacy of Thomas Hardwicke’s journey to Srinagar in 1796

摘要

In 1796, Thomas Hardwicke travelled through northern India between what is now Fatehgarh in Uttar Pradesh and Srinagar in Uttarakhand. Hardwicke collected and described plants encountered and had many of the plants illustrated from life. He published an account of the journey in 1799 including a list of plant species. I review the names validated in the original paper, and also those published subsequently by Sir James Edward Smith and William Roxburgh based partly or wholly on the material or drawings acquired by Hardwicke on the journey to Srinagar. The large collection of Hardwicke plant drawings now held in the British Library, and a smaller set in the Botany Library of the Natural History Museum, are considered in relation to the application and typification of plant names related to Hardwicke’s botanical exploration in India. The names of seven plant species were validly published in the 1799 paper ( Androsace rotundifolia Hardw., Ficus laminosa Hardw., Justicia thyrsiformis Roxb. ex Hardw., Linum trigynum Roxb. ex Hardw., Lonicera quinquelocularis Hardw., Salvia integrifolia Roxb. ex Hardw. and Volkameria bicolor Hardw.), plus one new combination ( Echites antidysentericus (L.) Roxb. ex Hardw.). As concluded by Britten more than a century ago, Ficus laminosa is the correct name for the fig variously referred to F. saemocarpa Miq. or F. squamosa Roxb. Smith based Rhododendron arboreum Sm. and Bignonia undulata Sm. on Hardwicke plants. At least a dozen Roxburgh names, including Crataegus integrifolia Roxb., Gardenia tetrasperma Roxb. and Morus serrata Roxb., are based, at least partly, on Hardwicke’s collections. In total, 23 names are lectotypified here and one neotype is designated.
