The Taraxacum flora of the Himalaya is revised; 75 species are mentioned of which 40 are new; moreover, a few subspecies and forms are described. Of the 75 species 64 could be referred to 11 different sections, of which 5 are new; for 11 species no section could yet be indicated, partly on account of the absence of achenes or because the latter are but inperfectly known. The western Himalaya especially is rich in Taraxacum species. Great differences occur between the western and eastern parts, and also between the northern and southern ones. Very few Taraxacum species descend into the lower regions and into plains situated at an altitude of less than 1800 m.
