The flower stem is 200-560 high x 2-3.5 mm wide and there are 2-15 flowers per spike.  The flowers are 15-30 mm across, deep blue with darker veins, externally brownish. Sterile bracts 2-3, large, lowest bract leaf-like. Sepals and petals 8-18 x 4-8 mm. Column 5.5-6.5 x 2.5-3.5 mm, white to pale blue; post-anther lobe 1.5-2.5 x 1.5-2 mm, yellow with dark purple collar, curved, slender, notched, lobes toothed; column arms 1.5-2.3 mm long, obliquely erect; hair-tufts mop-like, dense, white, with hairs 1-1.6 mm long.

Distribution

Thelymitra kangaloonica (Thelymitra sp. Kangaloon) is only known to occur on the southern tablelands of NSW in the Moss Vale / Kangaloon / Fitzroy Falls area at 550-700 m above sea level.  It is known to occur at three swamps that are above the Kangaloon Aquifer. These swamps are a part of the ecological community "Coastal Upland Swamp" which is listed under the NSW Threatened Species Conservation Act 1995 as an Endangered Ecological Community, also known as “Temperate Highland Peat Swamps on Sandstone” which is listed under the Environment Protection and Biodiversity Conservation Act 1999.

The majority of known plants are located on land managed by the Sydney Catchment Authority. One small population is located in Budderoo National Park. It is likely that the number of mature individuals of Thelymitra kangaloonica (Thelymitra sp. Kangaloon) is very low, with less than 250 plants known
