SUBGENUS Andreettaea
"A monotypic genus that vegetatively is similar to many others: small and caespitose with narrowly obovate leaves borne by short ramicauls with an annulus. The non-resupinate flowers are borne successively in a few-flowered raceme about as long as the leaves. The shortly acuminate sepals are connivent to the apex except for the lateral sepals which part in the middle on the dorsum of the flower to form a tiny, elliptical window to the interior. The species seems most closely allied to the species of P. subgen. Specklinia." Text by Carl Luer Icones Vol III 1986
