  1. APOCYNACEAE (including Asclepiaceae)

  2. general Asterid Characters fused corolla stamens adnate to corolla stamens equal to or fewer than perianth lobes gynoecium 2-carpellate

  3. APOCYNACEAE magnoliids rosids Current Angiosperm Phylogeny Group Tree for Flowering Plants 2016 monocots asterids core eudicots eudicots

  4. GENTIANALES • Asterids with • opposite leaves • radial symmetry • contorted petals

  5. Allamanda and Dipladenia APOCYNACEAE laticifer in Alstonia • milky latex • short filaments • superior ovary

  6. Vinca (periwinkle) local and typical Apocynaceae

  7. Common Tropical American Apocynaceae

  8. Stemmadenia and Tabernaemontana – American treelets of moist and dry forests

  9. Bird-dispersal of fruits: Characteristics of Stemmadenia that enhance dispersal include peak fruit availability in dry season, slow rate of opening, seed protection until maturation by husk, bright color of arils, relative accessibility and ease of separation of seed from husk and aril from seed, and high nutritive value of the aril. McDiarmid, R.W., Ricklefs, R.E. and Foster, M.S., 1977. Dispersal of Stemmadenia donnell-smithii (Apocynaceae) by birds. Biotropica, pp.9-25.

  10. Thevetia

  11. Climbers: Marsdenia

  12. Plumeria and Pseudosphinx tetrio

  13. On Plumeria, herbivore damage by caterpillars of the sphinx moth Pseudosphinx tetrio is restricted primarily to the wettest season, consistent with the hypothesis that early leaf flush and reproduction has been selected to avoid herbivory.

  14. Asclepias

  15. The African xerophytes

  16. Stapelia - African carrion-insect dispersed flower

  17. Pachypodium African succulent

  18. Hoodia

  19. Huernia South Africa

  20. Medicinal and Toxic Apocynaceae

  21. Nereum oleander:cardiac glycoside poisoning DIGITOXIN from Digitalis

  22. Catharanthus – leukemia medicine vinblastine vincristine

  23. Rauwolfia, antihypertensive reserpine

  24. The Gentianalessignature: monoterpene indole alkaloids Apocynaceae Rubiaceae Apocynaceae vinblastine reserpine vincristine vinblastine
