The main sources of taxonomic nomenclature used was POWO (2024). "Plants of the World Online." Facilitated by the Royal Botanic Gardens, Kew. Published on the Internet; http://www.plantsoftheworldonline.org/
On occasions Tropicos, https://www.tropicos.org/home and Catalogue of Seed Plants of the West Indies Acevedo-RodrÃguez, Pedro;Strong, Mark T., available online, were also consulted. There have been many "accepted name" changes, Using the seach box will help find species by previously-used synonyms.
Geographical distributions are given. From this it is possible to deduce whether a species is likely to be native to Saint Lucia or naturalized. For example, if the distribution is described as tropical America, this includes Saint Lucia. Thus that species is likely to be native. However, rarely, it could also have been introduced by people from a nearby island, either accidentally or on purpose, and thus would be naturalized. It is also possible to deduce from distributions if a species is endemic to Saint Lucia, or the Lesser Antilles, or the Caribbean.
The images of wild flowering plants and gymnosperms are often not of a single specimen. Rather they represent appearances of the species throughout its local range and life-cycle. Although this leads to the risk of mixture of similar species, I have minimized errors by making a complete set of independently-checked, (mainly at the University of Puerto Rico Rio Pedras by Franklin Axelrod) vouchered herbarium collections. I am confident that there will be relatively few errors but when you find them please let me know. Ruler is mm and cm unless otherwise stated.
The cultivated species albums are not based on herbarium specimens and given the number of cultivars and hybrids involved, there will be some mistakes. Not all internationally used common names are included. The best way to look for a species might be to use the search page. I have not included wild species that are occasionally planted such as Melocactus intortus.
The local medicinal album is based on contacts with local practitioners. One of the problems is that different practioners use the same plants in quite different ways.
