Ya tropical or equatorial trichs of pure sat are smaller and the density is also relative to high UV and T° so little montagnard or sub-alpine altitude helps but nothing compared to extreme alpine situ of Hindu Kush or Himalaya.
Bigger trichs is the transformation and adaptation of very high extrem limit elevation which goes hand in hand with broad wide leafing and smaller stature. All logic and so simply, i’m really surprised to be the only one? to have understood this indica (Nuristanica) process of evolution!
Anyway no places at 3000m alpine for pure sat tropical or equatorial
