Verticordia roei is a shrub which grows to a height of 1 m (3 ft) with a single main stem at its base. The leaves on the stems are linear to narrow elliptic in shape, triangular in cross-section, 1.5–4 mm (0.06–0.2 in) long and have a rounded end.[2]
The flowers are scented and arranged in corymb-like groups on erect stalks from 12–20 mm (0.5–0.8 in) long. The floral cup is a broadly hemispherical in shape, about 1.5 mm (0.06 in) long, ribbed and covered with short hairs. The sepals are creamy-white, sometimes pink, 6–7 mm (0.2–0.3 in) long, with 5 to 7 long-hairy or feathery lobes. The petals are a similar colour to the sepals, 4–5 mm (0.16–0.20 in) long, dished with small teeth around its edge. The style is 1–3 mm (0.04–0.1 in) long, with a few short hairs. Flowering time is from October to November.[2]
Verticordia roei was first formally described by Stephan Endlicher in 1838 and the description was published in Stirpium Australasicarum Herbarii Hugeliani Decades Tres. The type specimen was collected by John Septimus Roe.[1] The specific epithet (roei) honours Roe, the first surveyor-general of Western Australia.[1][2]
Alex George undertook a review of the genus Verticordia in 1991 and described two subspecies:[3]
George placed this species in subgenus Verticordia, section Catocalypta along with V. inclusa, V. apecta, V. insignis, V. habrantha, V. lehmannii and V. pritzelii.[3]
This verticordia usually occurs in sandy soil, often with clay or loam over laterite. Subspecies roei is widespread and locally common in areas between Merredin, Boorabbin, Wickepin, Hyden and Lake Grace[2] in the Avon Wheatbelt, Coolgardie, Esperance Plains and Mallee biogeographic regions.[6] Subspecies meiogona has a smaller distribution near Dalwallinu and Mukinbudin in the Avon Wheatbelt and Coolgardie bioregions.[7]
Subspecies meiogona is classified as "Priority One"[7] meaning that it is known from only one or a few locations which are potentially at risk.[8] Subspecies roei is classified as "not threatened".[6]
Subspecies roei has proven to be difficult to propagate and maintain in cultivation but more success has been achieved with subspecies meiogona. The latter subspecies has been grown from cuttings and by grafting onto Chamelaucium uncinatum rootstock.[2]
