       | I couldn't see where the article addresses it but why can't we
       | eat oak or maple leaves? Or say palm fronds?

         | fibrosity (if that's a word, else make it one), cookability
         | (ditto :), digestibility, being non-poisonous, etc.

       | My favorite green is not listed there: leek, I love the green
       | parts (still eat the white part, but later), and raw. Onion
       | leaves as well are excellent. Don't throw them away!

         | carefully harvesting a few leaves each spring, leaving the
         | bulbs alive so they can come back the next year.

         | Leeks confit is one of the most delicious things you can eat.

           | I rarely have it these days, but back when I ate animals,
           | leek confit simmered in duck fat used to be such a treat for
           | me. They're great simmered in any fat really, but that one
           | always struck me as such an awesome savoury combo.

       | I thought we ate the greens we do because we saw other animals
       | eating them and decided they were safe to eat (from as the
       | article puts it, _chemical & physical weapons_) based on that.
       | From there, we probably selected seeds from the tastiest/easiest
       | to harvest plants to replant, and thus that's how we ended up
       | where we are today (or at least before we figured out more
       | advanced GMO techniques).
       | 
       | I thought that was the direction this article would end up going.
       | I mean, could we or banana trees have evolved differently so that
       | we wound up eating the banana leaves and not just using them as
       | wrappers? Would our teeth have to look like a squirrel's? Would
       | the bananas themselves have to be different for the tree to grow
       | so that leaves are tasty to us?

         | I am pretty sure besides migrating, we eat the leaves our
         | parents eat, all the way back too...well..."other animals".

       | I suspect most greens eaten worldwide fall within the same taxa
       | as those described in the article. For example, the Chinese eat a
       | vast variety of cabbage/mustardy plants, but botanically they're
       | all _Brassica rapa_.

         | Spinach is the biggest exception i can think of - _Spinacia
         | oleracea_, in the Caryophyllales, a different order to the
         | Brassicales.
         | 
         | I don't think Indian cooking uses a lot of brassicas as greens.
         | Lots of spinach, plus amaranth, also a Caryophyllale, and
         | fenugreek/methi, a Fabale. Mustard leaf is a brassica, though.

           | Cabbage is a brassica, right? Indians eat lots of cabbage,
           | north to south. And a lot of cauliflower, also a brassica.
           | Alu gobhi (a dry veg dish of potato and cauliflower) is a
           | dish famous even in the West. I read somewhere that Bryan
           | Adams enjoyed it on an India tour, some years ago. I don't
           | like it much, personally (but don't dislike it either).

           | I feel like (at least modern) Indian cooking uses quite a bit

             | I think this has more to do with modernity and monoculture
             | than it does with the types of greens a culture originally
             | ate; usually the left behind greens are less tasty, more
             | ... strongly flavoured, and harder to grow. IIRC small
             | areas of japan have odd greens eaten as a customary thing,
             | whether they make up a majority of foodstuffs i cant say. I
             | believe greens were usually eaten only sparingly
             | historically rather than the salad heavy diets pursued
             | today. (lots of scary stuff on unwashed, uncooked greens)

         | In Turkey, we eat grape leaves as well. Do they fall into same

         | 
         | Edit: The article seems to refer that grape leaves are edible
         | but it also says that grape leaves were not included in this
         | article on purpose.

           | be completely wrong, but I've never seen them just eaten,
           | always as a functional part of a recipe.

             | It happens, but not often. You can use grape leaves in
             | salads, and even in pesto. I've also used them dried and
             | crumbled as an accent. They've got a tannic bite that
             | contrasts well with mild flavors like rice and soft
             | cheeses.
             | 
             | Even so, you usually don't base a whole dish around them
             | the way you can with other leafy greens. The tannic bite
             | easily becomes too much.
