In an earlier post I reported that I had found one solitary Maroonhood Orchid.  Since then, I’ve discovered three small colonies.   However, I’m unsure if one of these colonies is the same species, or a sub-species.  Can anyone help me to correctly identify it from the photographs below?  I have spent quite a bit of time reading and researching but so far I have not come across anything I can use to specifically identify the plant in Photo 2, so any help you can provide would be very much appreciated.

Photo 1:  Maroonhood

One of the Orchids is definitely a Maroonhood, with dark colouring on the dorsal sepal, the petals, the lateral sepals and the sinus.

This flower meets all of the descriptive criteria for a Maroonhood., with dark colouring on the Galea, the Sinus and the Dorsal Sepals.


Photo 2: Please identify.   Is this also a Maroonhood?

Comparing the dark markings on this flower to the one above, it is evident that the Dorsal Sepal is green, and only the petals at the sides of the Galea are maroon or brown in colour.  There is also just the slightest hint of a blush on the Sinus.  All of the plants in this colony had the same characteristics, so it is not just an anomaly for this individual plant.

Is this a Maroonhood or a different species? Note the green dorsal sepal, green lateral sepals, and mostly green sinus.
