hello guys, I'm carrying out a research on a topic, but i need to take some samples to the lab and analyze them. those sample I want to analyze are tuber yams. sweet potatoes and cassava. N:B: my discipline is far from agricultural science or related fields. My challenge is not how to get those sample as they are in abundant in the market. I will need to specify the specie of each sample used, which i cannot identify.
For instance, I wanna use discorea rotundata (white yam), which i know is common in the market, but how will I differentiate them.

Please, if you can be of help on this I will be grateful.

Get ur already collected samples identified by a Taxonomist if ur research work is important

Though I studied agriculture but I only major in entomology (insects). What you need atleast is an agronomist especially a plant taxonomist . These people are few ... But you can get someone from the faculty of agriculture in the university located in your state. In am very sure he/she will be wlling to help
