Ive noticed some members were expiermenting with different acacia varieties and wonder about these 2 for some research? Would they make for a good project or should I not waste my time?

Also are the barks supposed to appear pinkish like MHRB or do they differ looking basicly brown? If one knows that is,

i do not think bark color is indicative of alkaloid content so much as species.

Thanks for the response. Also I dont think Ill be ordering these varieties as I found some confusa from a different source in amounts that I can afford to pay. The information would still be valuable though if someone knew the answers. I saw another catechu post after posting this and it didnt seem like it was active but the materials used for the extraction were kind of questionable.
