I know that grass plants have the oldest cells at the leaf tip, any other plants?  [:-\]

Wouldn't that make them "basal meristems?

I'm not sure - cacti, perhaps?

Hi there!

hmmm...scince "apical" means tip, an apical meristem shoulnīt be at the base of something.
But, as far as I know itīs pretty normal for a leaf to have itīs oldest parts at the Tip.

So far as I was aware grasses are the only plant to grow in this manner, which is why they benefit from grazing. I think grasses have up to 5 meristems, depending on species, one of which is mid stem.
If brains were made of dynamite, I wouldn't have enough to blow my nose.

I've found:

Longitudinal section of a basal meristem in a cactus spine (Morawetzia doelziana). Spines grow upward due to a meristem located at their base; consequently this is a basal meristem.
