4th pic of capsule split along the lower side.
5th pic of the seed covered in a netted membrane.
6th pic of internode - at each a green short leaflike extension, seems to later turn brown and drop off
7th pic - stigmas at the internodes

Growing together with T. lucens (which it resembles quite a bit when not flowering).

The first couple of pics are of male specimens: T. guthrieae on the left, and T. lucens on the right.

The fruits of T. lucens are the round ones (i.e., as broad as tall), whereas T. guthrieae have fruits that are longer than tall. Also, the taller plants in the photos are T. lucens, whereas the shorter ones are T. guthrieae.

Moreover, the spikelets themselves are also quite different, with T. guthrieae being much larger.
