Is there a botanical expression or definition to distinguish
between,
perennials which die back each year, but regenerate from the old
rootstock,
and perennials which do not die back, eg cactus, succulents, trees,
etc.?


Some old (19th century) material on the topic

I think the term you're looking for is herbaceous perennial.


Thanks for that.
I found it interesting.
It says a lot that I'm in tune with the 19th century! ;-))


The terminology is still current - I wouldn't have pointed you at the
page otherwise. The point which I wished Bentham to make for me was that
the division of plants into these groups isn't cut and dried.

Elsewhere you'll find people talking about shrublets and treelets, and
herbaceous perennials divided into bulbous, cormous and tuberous
(collectively "bulbs"), rhizomatous, stoloniferous, etc., perennials.
