There is no known flora or plant species called "elbem" in New South Wales or anywhere else. It's possible you might have misheard or misspelled the name.

To help you find the specific plant you're looking for, please provide more information:

* Can you describe the plant? (e.g., what does it look like? What color are its flowers? Is it a tree, shrub, or herb?)

* Where did you hear the name? (e.g., in a book, website, or from someone)

* Do you have any other details about the plant? (e.g., its uses, its habitat)

With more information, I might be able to help you identify the plant you're looking for.
