Please select a clade/taxon at the level of the order or smaller (i.e, family or genus). At least one of your references should be a primary research article (i.e., one that includes an Introduction, Methods, Results, and Discussion) I collected a lot of Legumes for my herbarium collection for this class so you could do that but it’s really up to you what you want to write about.
Circumscription. Each student will be responsible for writing a brief circumscription of a clade that is of particular interest to you. Strictly speaking, a circumscription should summarize the nomenclature, morphological/anatomical (and biochemical) descriptions, and phylogenetic relationships of all the taxa included within a monophyletic group. However, for this assignment you will only have to include the 8-12 taxa in your circumscription. I will be posting a complete rubric in the next few days, but a few things to keep in mind.
a) Ensure that the nomenclature for the taxa that you are including is current. The best way to do this is to check one or more authoritative websites. The most reliable ones that I have found are: http://plants.usda.gov/, http://www.itis.gov/, or http://www.mobot.org/MOBOT/research/APweb/welcome.html. The USDA and MOBOT sites also provide good examples of what a circumscription looks like.
b) Look up the relationships between the taxa included.
c) A good circumscription will include information about the geographic range of the taxa included.
d) Note that for particularly diverse clades you can choose to focus on higher level taxa. For example, you could circumscribe twelve genera rather than twelve species. You could also circumscribe a subfamily, tribe or genus rather than an entire family or order.
