  • 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 pictures along with the descriptions. I found that even when I wasn’t sure what the name of something was, comparing it to a picture really helped in figuring it out on my own. Anyways, I used the dichotomous key video tutorial as a guideline for mapping out my key, in addition to the violet dichotomous key from the practice exercises. Here’s what I came up with:

     

    A.   Plant Woody- B

    B. Needles, branchlets glabrous; cones 3-6 cm long……………………………………. 1)  Picea glauca

    A’ Plant Non-woody- C

    C. Flowers with petals present- D

    C’ Flowers with petals lacking- E

    D. Petals white; 4 small petals; pubescent pedicels and stems………………………… 2)  Arabis divaricarpa

    D’ Petals purple; 6 large petals; pubescent stems; many stamen……………………. 3)  Anemone patens var. multifida

    E. Flowers arranged in catkins; young pubescent capsules; yellow stamens……. 4)  Salix bebbiana

    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. I could even figure out how to identify all the bins. So if anyone can take pity on me an post some advice to help me out I would greatly appreciate it.

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

    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!
