Dicrastylis costelloi is a species of plant within the genus, Dicrastylis, in the family Lamiaceae.[3] It is found in Western Australia, South Australia, the Northern Territory[3] and Queensland.[4]
Description
Dicrastylis costelloi is a shrub, growing to about 40 cm high on red sands. Its stems are roughly circular in cross section with no peltate scales. The opposite and entire leaves are 8-25 mm long by 3.2-6 mm wide, and have branched (dendritic) hairs. There are bracteoles (1-2 mm long), and bracts (5-9 mm long. The flowers are sessile. The calyx has five lobes (1.5 mm long), covered in dendritic hairs, and the white or cream corolla is 4.5-5 mm long, with no dots or stripes in its throat. There are five stamens. In Western Australia it flowers in October.[5]
Taxonomy
It was first described by Frederick Manson Bailey in 1891 as Dicrastylis costelloi.[1][2] The type specimen was collected "near Lake Nash, on the boundary line between Queensland and the Northern Territory of South Australia" by M. Costello whom the species epithet honours.[2] An isotype (MB0011041108) collected by Costello at Lake Nash is held at the British Museum.[6]
