Atlas of British and Irish Hawkweeds

Second-Hand Paperback | Published by: BSBI 2018 | ISBN: 9780901158543. 2nd Edition. Book Condition – Very Good. Dust Jacket – Very Good. A BSBI publication Softback wth a protective plastic cover, in very good condition. This second edition incorporates a significant number of records from field work and from additional herbaria. The bibliography gives publication details for the new or renamed species. Plants that with present taxonomic knowledge cannot be ascribed to species and share the characteristics of a basal rosette, cauline leaves 0-1(2), phyllaries with numerous to dense glandular hairs and without simple hairs are referred to informally as H.exotericum agg. No attempt has been made to map such plants, which are widespread. Hieracium species thought to no longer occur (extinct native or introduced species with no recent records) are relegated to Appendix 1, together with plants of uncertain occurrence. Appendix 2 is a new addition, with images of selected leaves of all species with blotched or spotted leaves, as this can be a short-cut to identification. Sell & Murrell?s (2006) numbering has been retained for ease of cross-referencing, adding a letter for additional species, usually at the end of the relevant section (e.g. 46a Hieracium jonesianum).
