Anyone know what this vine is? Very tiny toothed leaves and tiny little reddish-pink (or pinkish-red?? ) trumpet shaped flowers with a paler throat. This is growing at the Houston Zoo, hanging down over a tall "rock" wall. It was hanging down maybe about 6 feet in total length in full sun. Not clinging in any way and doesn't appear to have the ability to cling - just hang or drape. Stems are very straight and slightly stiff. Stems were also somewhat more angular than rounded.

Thanks!

That interesting plants.
Dont have any idea yet. Wish other member can recognize it soon

Looks a little like Firecracker plant except with more leaves - Russelia equisetiformis

The blooms do look like Firecracker Plant (Russelia equisetiformis)

Thanks. It does look much like some type of russelia, but there was no arch to the stems at all - they just hung straight down all neat and tidy - two words that would never be used to describe Russelia equisetiformis!

Unfortunately, there doesn't seem to be much info out there on more than just a few Rusellia types - none of which fit this plant. This gives me some direction, though!
