Edinburgh, William Blackwood and Sons, 1842-1845. Two volumes in two. 8vo (24.8 x15.7 cm). Half-titles and titles, 356 pp. [xxi, 1-152; xxvii, 153-311]; 142 [I-LXVI; LXVII-CXLII] fine, lithographed plates. Original uniform, green, blind-stamped cloth with gilt title on the spines and gilt floral vignette on the front boards. Yellow endpapers. Top edges gilt.

A rarely seen set with author's dedications. Both copies signed by the author, the British botanist Richard Parnell (1810-1882), to the Royal Society of Edinburgh. The fine, detailed plates are by Parnell himself. The title of the second volume is somewhat misleading, as it deals primarily with the grasses of Ireland and England, being an addition to The grasses of Scotland, as explained by the author in the second preface. Cloth at hinges of second volume partly chipped, but holding firm, otherwise very good, clean. Nissen BBI, 1492.
