“A Description of the Genus Pinus” is a seminal two-volume work by Aylmer Bourke Lambert, first published in the early 19th century, with the second volume released in 1824. This comprehensive study offers detailed descriptions and illustrations of various species within the genus Pinus, reflecting Lambert’s extensive research and dedication to botanical science.

The second volume expands upon the first by introducing new species and providing additional insights into previously described ones. It includes descriptions of species such as Pinus lambertiana, P. pallasiana, P. spectabilis, P. excelsa, and P. deodara. Lambert’s meticulous approach is evident in his detailed observations of each species’ morphology, habitat, and distribution. The volume also features illustrations that enhance the textual descriptions, offering readers a visual understanding of the species’ characteristics.

Beyond the genus Pinus, Lambert extends his study to other members of the family Coniferæ. He provides descriptions and illustrations of species such as Araucaria imbricata, A. brasiliana, Dammara australis, Thuja dolabrata, Taxodium sempervirens, and T. distichum. This broader scope underscores Lambert’s commitment to documenting the diversity within coniferous plants, offering valuable insights into their taxonomy and ecology.

An appendix in the second volume, contributed by Mr. Don, provides an account of the Lambertian herbarium. This section offers readers a glimpse into the extensive collection of plant specimens amassed by Lambert, highlighting his contributions to botanical research and the importance of herbariums in the study of plant diversity.
