At an International Cargo Port a Shipping Container Has Been

At an international cargo port a shipping container has been discovered that is bereft of identification but was known to have been unloaded from an Australian vessel. Authorities need to ascertain where in Australia the container may have come from so as to gauge quarantine concerns. The only clue to its origins is a small, leafed branch that is found inside it. Upon examination it is found to have small, hard leaves, short internodes, thick cuticles, sunken stomata in grooves, a high proportion of lignified cells and thick-walled hypodermal cells between the epidermis and photosynthetic mesophyll. What kind of flora is this, and how useful is it in determining where the container may have been loaded?

A) Sclerophyllous, which is of very limited assistance given that such plants dominate the Australian landscape.
B) Sclerophyllous, which limits the container's origins to northern tropical regions.
C) Matorall, which limits the container's origins to southern alpine or subalpine regions.
D) Chaparral, which is of very limited assistance given that such plants dominate the understory of most Australian environments.
E) Phrygana, which limits the container's origins to the southern tip of Tasmania or Macquarie island.
