Assessment Information [top]

Red List Category & Criteria: Endangered B2ab(iii) ver 3.1
Year Published: 2004
Date Assessed: 2004-04-30
Assessor(s): Miller, A.
Reviewer(s): Abuzinada, A.H. & AL-Eisawi, D.M.H. (Arabian Plants Red List Authority)
Justification:
Only known from a ravine in the south of Soqotra where it occupies an area of less than 50 km². It is strongly suspected that this area is threatened by the long-term trend of lower rainfall in the region and would be particularly vulnerable to the effects of global warming.

Habitat and Ecology [top]

Habitat and Ecology: On cliffs in sheltered limestone ravine in deciduous woodland. Altitude of 550 m.

Aromatic subshrub with erect, woody branches. Leaves clustered towards branch tips, narrowly oblong to obovate, 3–7 x 1–2 cm, entire, densely glandular. Capitula terminal, solitary, 1–1.5 cm diameter; peduncles 1.5–7 cm; ray flowers absent. Pappus outer scales absent (much reduced appearing as a 'rim' to the achene).

This is one of several plants (e.g., Prenanthes amabilis, Pluchea glutinosa, Sida cordifolia) collected in the 19th Century from near Kischen in the northern Haggeher mountains but not seen there since. However, P. aromatica was recently found on cliffs on an isolated ravine in southern Soqotra and perhaps some of these other plants should be searched for in some of the well-wooded valleys draining south from the Haggeher. It is not clear what the relationships of Pulicaria aromatica are. It is possibly related to P. vieraeoides on the basis of achene characters, habit and inflorescence.
