Good evening: The dichotomous key I created to classify the species displayed in Bins 1-4 is embedded within this posting. Thanks! Here’s the second version with edits & corrections. – ELMV
Here is a photo of the herbarium specimen that I made while I was in Hooper Bay, AK last summer. This was my first time creating an herbarium specimen so it was a great learning experience. Here are the herbarium specimen I made for this assignment. I just used …
Hi everyone, I spent the weekend out of range of wifi and cell service, but I’ve got the day off to catch up today. I am really enjoying learning a new vocabulary. I used both the Cody and Hulten keys for keying out the violets. The second violet specimen was …
I was also confused by this assignment, but I believe the intention was to treat this like the lego exercise and devise our own dichotomous key from the bins provided. Here’s mine:
I made my plant press out of pieces of plywood from our garage and several textbooks. Berries are near and dear to my heart so I pressed two species of berries I have in my community. The thimbleberry is my absolute favorite berry of all time and I bushwhacked through …

I went flower hunting last night and I must have found at least 20 different varieties of flower /at least/ on UAF’s campus! What an enlightening and fun experience. One of my favorite flowers is pictured, pressed. Lonicera tatarica, an invasive honeysuckle originally native to Siberia. I think …
I struggled with this assignment too. I’m not sure how technical it is suppose to be and ended up spending a lot of time trying to find the scientific names of each one and this is what I have: Dichotomous-Key
I have my daughter’s little plant press so I am going to press little plants! More to come … they need another day or so.
