::Well, I'd like a disambig somewhere between the two.  I'l leave it to you to clear up what is or isn't called "horsetail" within the articles.  (And FYI I have PLENTY of it on my property, how DO you kill the darn stuff, anyway??? It happens to be somewhat toxic to horses, ironically, I spray it, mow it, pull it, burn it, and it just seems to come back stronger...)  Here's my concern:  If someone here on wiki is wanting to link the article Tail (horse), it is pretty common to write "horse tail" and it isn't real obvious to search for a parenthetical title (which we are doing at WPEQ to distinguish most of the horse articles from other things of the same name... we have Mane (horse), Gait (horse), etc...) .  So even if you insist on a one stop jump to "horsetail," then can you at least kindly allow an "otheruses" disambig to the disambig pages there?
