Thank you for clarifying Steffi! I definitely made that assignment harder than it was meant to be. I redid it and this is what I came up with. Dichotomous Key

This seems right, not positive :/ A.   Flowering plant – B B. White flower     Bin 2 B’. Purple flower   Bin 3 A’.   Non-Flowering plant – C C. Cones            Bin 1 C’. No cones      Bin 4  

Here’s my key. Thank you Steffi for the added direction! Ann Ann’s Dichotomous Key of Bins 1-4

Dichotomous Key A. Leaves needlelike, plant tree form, fruit is a cone (Bin 1) A.  Leaves flat, plant herbaceous and flowering B.  Leaves Simple (Bin 4) B.  Leaves Compound C.  Flowers contain six petals, violet (Bin 3) C.  Flowers contain four petals, white (Bin 2)

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  

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 …

It seems I am not the only one struggling with this assignment. I understand the concept of dichotomous keys but I find it very difficult to decipher certain plant characteristics through a photograph. For instance, even on the exercise with the two different species of violets, I keyed out different …

I chose to focus on just one feature present in the four bins. (Thank you, https://northernwoodlands.org/articles/article/needles-leaves). And that was plenty. It’s a bit of a logic puzzle. It took me a long time to think my way through labelling the choices A/A1—F in the second version I wrote. Still not …

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

This assignment was pretty interesting and challenging (for me) overall. I’m still getting used to the vocabulary, so this took longer than expected, specially when I was trying to understand the Hulten Master Dichotomous Key to identify the plants from the bins. It helped a lot to find and use …

Dichotomous Key 2 So I have to say this is the first class I am legitimately worried about failing because I feel like I’m lost. I understood the LEGO example no problem, I get the vocabulary terms, but somewhere combining the two it is like I’m back at square one. …

Did the best I could, lots of uncertainty but a lot of fun trying. I think I got 2 of the 4 right. D Key

Hi, To be honest i’m not sure if i did this assignment correctly, but i did a fair job of using dichotomous keys to ID the plants assigned in the bins…though the Salix is most likely wrong!     Dichotomous Key
