First published in 1998. This volume (I) only contains the text and line drawings of the original (88 pages) without the colour plates (available separately as Volume II).
From a review by Dick van der Werff in New Rare and Unusual PlantsÑOctober 1998: ÉIn depth and fascinating with colour photographs together with propagation, cultural and (thank goodness) a section about the naming of various species, clears up many points of confusion from the past. There are so many more species of Phlomis than I ever imagined. For more reviews see: www.nccpg.com/gloucestershire/book.html
