-ii- J. D. Hooker's Antarctic Expedition on which Taylor published, nevertheless the moss specimens in this herbarium, over 250, are probably the largest set outside Britain. These have been freely annotated by Sullivant, to whom the herbarium was loaned soon after it came to Harvard, and who kept it until his death. The specimens are generally small, but usually accompanied by notes and sketches. The proportion of types is remarkably large, including 120 holotypes of Taylor's published names. We have underlined types on the index, but only in the case of Taylor's have we made the bibliographic confirmations or distinguished holotypes from others. We have also underlined the large number, some 240, of Taylor's manuscript names, which are indicated as "Tayl. ms." From Taylor's time to the present, his herbarium names have been picked up occasionally, either by validation or in synonymy, by Hooker, Wilson, Mitten, Spruce, Brotherus, Hartmann, Dixon, W. Meijer, and probably others we have not noted. As is the practice with the reference herbaria at the Farlow, names in the original herbarium have not been altered to correspond with current nomenclature, which may be found in Index Muscorum.
