<jats:p> Seven alkaloids have been isolated from L. clavatum Linn. collected in Jamaica, clavolonine C<jats:sub>16</jats:sub>H<jats:sub>25</jats:sub>NO<jats:sub>2</jats:sub>, fawcettiine C<jats:sub>18</jats:sub>H<jats:sub>29</jats:sub>NO<jats:sub>3</jats:sub>, base A (now named fawcettimine), lycopodine, dihydrolycopodine, and L.2 (acetyldihydrolycopodine). Fawcettimine is a secondary amine now shown to be C<jats:sub>16</jats:sub>H<jats:sub>25</jats:sub>NO<jats:sub>2</jats:sub>. The isolation of deacetylfawcettiine C<jats:sub>16</jats:sub>H<jats:sub>27</jats:sub>NO<jats:sub>2</jats:sub> in quantity from a later extraction indicated that there was a seasonal variation in the alkaloid content of the plant. These bases differ from those obtained from L. clavatum of Canadian or European origin.
