TAXONOMY OF CENTRAL AMERICAN AND MEXICAN PINES |
Over the past decade, seed of some Central American and Mexican pines has been distributed for international provenance trials and for the establishment of ex situ conservation stands. In parallel with the evaluation work underway in a large number of countries, further botanical and genecological exploration has been carried out in the regions of natural occurrence of the species. These studies have resulted in a number of proposals for taxonomic splits and changes in nomenclature, many of which are potentially of great practical importance. |
Some of the provenances under review include, among others, the important Nicaraguan Pinus oocarpa seedlots from Yukul (K42, K94, K101, K128, K140); San Rafael del Norte (K44, K142); and Camelias (K1, K2); and seedlot K11, El Conacaste, from Guatemala. |
In a future issue of FGRI, we hope to publish a more exhaustive account on these matters. Presently, we would like to draw your attention to the following articles and notes: |
