Now with thi pic of a strelitzia nicolai, I have new doubts (~_~,

There seems to be also a place where the blade joins with the stem into a v
- I was referring to the very bottom of that v as the place where it joins
to tell if it's obtuse or cordate, but I noticed you said "extend down
*slightly*". Maybe it does; it's hard to tell. The v part makes me think
it's obtuse, but above that part sometimes it does cordate slightly (not on
all leaves, and never on both sides). I think I'll stick with the
probability it's a nicolai for now...
