I'm normally a big fan of including any and all accurate information on Wikipedia. However, with this many articles, I'd be concerned about the ability of any human editors to actually notice malicious misinformation. If a random person edited one of those arcticles to change an obscure fact to an incorrect statement, would anyone notice?

That's a problem Wikipedia has in general; improvements to Wikipedia's botany coverage are not going to meaningfully change it one way or the another.
