Phylogenetic Tree
I created the phylogenetic trees displayed below. The first one is based on chloroplast genome sequences showing the species Coffea is most closely related to Jasminum from this stand point. (For more information click here) The second tree is based on my general knowledge containing the closest, most common relative of Coffea arabica, Coffea robusta. Coffea robusta is the second most consumed coffee, having a higher caffeine content and harsher taste, but less quality coffee. There are 84 other genera in Rubiaceae, and 6 total species known in Coffea. Chocolate and Black Tea are related to Coffee at the phylum level; all are angiosperms that have the unique characteristic of producing caffeine.
