Fig. 25 Distribution of Anacyclus linear ilobus. 



closely related Anacyclus clavatus and A. homogamos by the wider internodes of the rhachis 

 between the primary lobes, the broad fleshy retinate lobes, and the long red rhachis of the lower 

 leaves. It shows an advanced disc corolla structure, similar to that of A. nigellifolius, where the 

 lateral wings are expanded at the base into an anterior disc overlapping the cypsela, and is unique 

 in the genus by the possession of long spiny receptacular scales. 



Distribution and ecology: See Fig. 25. This species is endemic to Algeria. It grows on sand dunes 

 and disturbed sandy ground up to about 50 m around Mostaganem, La Macta, Oran and Cap 

 Falcon. 



Collections: 30 collections were examined, all from coastal areas around Mostaganem, Oran and 

 La Macta.

 sect, often dilated at the base; segments linear. Inflorescence a protracted corymbose cyme; 

 peduncles erect-ascending, 2-0-5-0 cm long only slightly thickened below the capitulum, densely 

 villous. Involucre 10-0-13-0 mm in diameter, turbinate-hemispherical, involucral bracts in 3 rows

 hyaline, slightly green above, scarious, lightly villous. Ray florets white; ligules 8-0-9-0x2-0- 

 3-0 mm, 2-3 lobed at the apex; tube 3-0-4-0 x c. 2-5 mm, anterior-dorsally compressed with very 

 narrow wings, female fertile. Disc florets 3-0-4-0 x 2-5-3-0 mm, infudibuliform, lobes equal. 

 Styles c. 3-5 mm long, branches c. 0-6 mm long. Stamens c. 4-0 mm long, anthers c. 1-8 mm long. 

 Cypselas slightly dimorphic, broadly obovate (in disc florets) to obcuneate-auriculate (in ray 

 florets), 4-0-6-0 x 5-0-8-0 mm, pale brown; lateral wings extremely thin, scarious, 2-5-2-75 mm
