This table lists all species profiled on PIER with the genus beginning with the letter L. An alphabetical index to all PIER species is also available. Also, the complete alphabetical of all PIER species is available, but it is a large list and may take a while to load on systems with slower internet connections. It includes those of environmental concern (including those that are probably of threat only to islands with high elevations) as well as agricultural and ruderal weeds. Each species is linked by its scientific name to an individual write-up containing relevant information.
Species are listed in alphabetic order. You can browse this list or use the "find" function on your web browser to search by scientific name.
