Snapshot: Gahnia vs. Gahnia

Sedges are a key component of the forest understory. Here, I just wanted to highlight the big difference between 2 native species of Gahnia is Hawai’i. The infloresence for the 2 is quite different. Pictured above is Gahnia beecheyi. It is still a common plant on many trails  on O’ahu. Pictured below is it’s congener, Gahnia aspera.

This was the plant from the Kaunala trail. Notice how much more robust the infloresence is on G. aspera. I don’t believe they are sympatric: G. aspera is typically found in drier areas than G. beecheyi. Keep an eye out for both.
