I know there are many many kinds of both, but usually they can easily be divided into two groups, because we can say that a potato and a sweet potato are commonly referred to by those two separate names, and usually not confused with each other by the people that grow them and consume them. </div><div class=""><br class=""></div><div class="">I am very comfortable throwing all grapes into “grapevines” or all oranges into “orange_trees” - but I don’t know about some obviously different fruits that share the same words - Asian pears look different, taste different - and most importantly - not considered a “pear” by the people that grow them - “pears” are “western pears” to them. So I feel comfortable saying that having “pear_trees” and “sand_pear_trees” is a good idea. </div><div class=""><br class=""></div><div class="">But when it comes to all the other trees I have never heard of until I was cleaning up that list (is a "Governor’s plum" a plum? Is a “Custard Apple” an Apple?), I was looking to see if there is some known way of putting the trees into usable categories or types for mapping without having people suggest them one by one - otherwise we’ll get odd regional or slang names - or things possibly grouped by distant mappers who don’t understand the nuances - like me with some of these trees. </div><div class=""><br class=""></div><div class=""><br class=""></div><div class="">Javbw</div></div></body></html>
