Verticordia sieberi Diesing ex Schauer |
Verticordia sieberi is a flowering plant in the myrtle family, Myrtaceae and is endemic to the south-west of Western Australia. It is a shrub with one main stem, often compact but sometimes openly branched and with pink to pale purple flowers in summer and autumn.
Verticordia sieberi is a shrub with a single main branch and which usually grows to a height of less than 1.5 m (5 ft). It is sometimes a compact, small shrub but may also be openly branched with the flowers held high above most of the foliage. The leaves are linear to elliptic, 2–8 mm (0.08–0.3 in) long and semi-circular in cross-section.
The flowers are scented and arranged in round or corymb-like groups near the ends of the branches, each flower on an erect stalk 2–4 mm (0.08–0.2 in) long. The floral cup is about 2 mm (0.08 in) long, smooth and hairy. The sepals are spreading, 2–3 mm (0.08–0.1 in) long, white to deep pink with 5 to 7 feathery lobes. The petals are a similar colour to the petals, erect, about 2 mm (0.08 in) long, with short hairs around its edge. The style is 4–6 mm (0.16–0.24 in) long, curved and hairy near the tip. Flowering time is usually from November to April but can occur at other times, depending on weather conditions.
Verticordia sieberi was first formally described by Johannes Conrad Schauer in 1841 from an unpublished description by Karl Diesing. Schauer's description was published in Monographia Myrtacearum Xerocarpicarum. The specific epithet (sieberi) honours the Austrian botanist Franz Sieber.
In his review of the genus in 1991, Alex George placed this species in Subgenus Verticordia, Section Verticordia along with V. crebra, V. helichrysantha, V. plumosa, V. stenopetala, V. harveyi, V. pityrhops, and V. fimbrilepis.
