  • Related speciesPoa sieberiana var. hirtella has leaves sparsely covered in flattened, short stiff hairs. It occurs in one known area in shrubby foothill forest. Poa sieberiana var. cyanophylla has very fine, rough, bluish leaves and is not tufted but roots along an underground stem. P. sieberiana is sometimes confused with Poa labillardierei and is probably more widespread in the Shire. The latter is larger with folded leaves. The lower floral bract has hairs only on the keel and veins and has a well developed web.
