Vines with shiny green leaves–roundish yet spiked with points–grow on a forested bank. This is German ivy, or Delairea odorata, a South African native that is a problematic invasive here in California. It can smother trunks, shrubs and ground cover with its vigorous stems.
It is also known as cape ivy, and is unrelated to the vaguely similar-looking English ivy.
