Palm Quiz: Extra Credit Answers

 

The extra credit answers are (drum roll please):

Question 3: Lodicea maldivicia (coco de mer, double coconut). The origins of Lodicea may have come from French king Louis XV, and it was definitely a compliment, not an insult to the king as the seeds were very valuable and given to nobility.Wikipedia states, "Until the true source of the nut was discovered in 1768 by Dufresne, it was believed by many to grow on a mythical tree at the bottom of the sea. European nobles in the sixteenth century would often have the shells of these nuts polished and decorated with valuable jewels as collectibles for their private galleries. The coco de mer tree is now a rare and protected species."

Question 7: Wodeyetia bifurcata (foxtail) palm. This species is endemic to the Cape Melville range, within the Cape Melville National Park in Queensland Australia. It was described in 1978, and was classed as a rare palm, both within Queensland, and on the IUCN's Red List of Threatened Species. (Source: Wikipedia)

Question 17: Archontophoenix purpurea (Mount Lewis King Palm). The common name "Mount Lewis" comes from the Mount Lewis National Park in Queensland, Australia, located on a penisula jutting out of the northeast side of Australia. In ancient Greek, the word "archon" means a ruler or leader, so all palms in the Archontophoenix genus are "king palm" genus. The second part of the scientific name, "phoenix", is translated as either the date fruits or trees, or a mythical bird. For those who really enjoy trivia, see the following links:

Question 18: Bactris gasipaes (Peach palm). Not only is the crownshaft is used for heart of palm, but the fruit can be eaten as well. See link:

Other palms mentioned and their edible food products are: Phoenix dactylifera - dates, Euterpe olercea - acai (also spelled assai), Elaeis guineesis - cooking oil, including the reddish dende oil used in Brazilian cooking. The other species in the genus, E. oleifera does not produced as much oil, so it is used only as a local suplly of cooking oil.

Question 19: Monocarpic palms include the genera of Arenga, Caryota, Corypha, Metroxylon (except M. amicarum), Nannorhopps, Raphia, Tahina, Wallichia. Give yourself two extra points if you named all 7 genera in addition to the Corypha genus.

Question 21. Sabinaria magnifica: Related to the Itaya palm. Quoting from Wikipedia: "Using morphological characteristics, they placed the genus in the tribe Cryosophileae and commented on its similarity to the genus Itaya. A phylogenetic study by √Āngela Cano and collaborators confirmed the placement of Sabinaria in the Cryosophileae based on four nuclear genes and the matK plastid gene. This analysis also identified Itaya as a sister genus to Sabinaria."

It is really great so many journal articles are posted free of charge on line. For a light hearted quiz, I know some of these questions get pretty deep into biology. But I want it really hard for anyone to get every question right. I still get some questions wrong!
