Streptoglossa tenuiflora is an upright, annual or perennial herb to 30 cm (12 in) high.

The pink or blue-purple "flowers" are arranged in loose corymbs and florets in a group of about 90.

Flowering occurs from April to October and the fruit is dry, one-seeded, about 2 mm (0.079 in) long, ribbed and covered in silky, flattened hairs.

[2][3] Streptoglossa tenuiflora was first described in 1981 by Clyde Robert Dunlop and the description was published in Journal of the Adelaide Botanic Garden.

[5] This streptoglossa grows on clay, edges of streams and mud flats north of Carnarvon to the Kimberley region.
