D'Aguilar National ParkThe flowers are quite small - about a cm long. A. excertus looks very similar to A. fornicatus (which we also saw), but to me, the main difference, which is clearly visible here, is that the dorsal sepal of A. excertus stands away from the column, while in A. fornicatus, it covers it.

Pale form of Acianthus caudatus

D'Aguilar National ParkIt was nearing the end of the flowering season, so a lot of the plants had seed capsuals on them. These very small plants only grow to be about 10cm high. However, they are deceptive, in that they can have an equally long stalk beneath the leaf that makes its way through the leaf litter down to the ground.

D'Aguilar National ParkHere you can see how the dorsal sepal "hoods" the column. This is the main difference (for me) between this species and A. exsertus, where the sepal stands back away from the column.

D'Aguilar National ParkThe underside of the leaf is a surprising purplish-red. You can get an idea of size from my thumb.

D'Aguilar National ParkThis is a very very tiny orchid. It grows to be about 10cm tall. We were lucky enough to find one still in flower, however, I was totally on the wrong angle so all you can see is the side! Oh well, you can at least see the distinctive leaf clearly.

D'Aguilar National ParkHere are a couple of plants. The one in the foreground is in flower, but unfortunately with the dim light and very narrow depth of field the flower ended up being out of focus.

D'Aguilar National ParkLike its cousin species A. exsertus, A. fornicatus also has a purplish-red underside to its leaf.
