138 BOTANY OF SOCOTRA. 



gradatim minora linearia obtusa v. cuspidata sed exthna scepe subspathnlata foliacea 

 intimisque jpquilonga v. longiora. Beceptaculum convexiusculum subalveolatum £ poll, 

 diam. Corolla flava ligula tridentata. Antherancm apices anguste acuta, caudis elongatis 

 simplicibus binis connatis. Styli lobi longi lineares obtusi papillosi. Achcnia subteretia 

 10-costata versus apicem pilis brevibus adpressis vestita. Pappi exterioris paleas in

Socotra. On the Haghier range south of Tamarida, at an elevation 

 over 2000 feet. B.C.S. nn. 402, 481. 



Distrib. Endemic. 



Another very remarkable Inuloid species. It is by no means common on 

 Socotra. We have it only from the Sicante range of peaks. 



The plant has all the appearance of a Psiadia, from which genus, however, 

 its anthers thoroughly exclude it. It also resembles the monotypic Canary 

 Island Viercea. But its incorporation in that genus is forbidden by the 

 achenes, and especially by its pappus. Technically there is no character 

 separating it from Pulicaria, but the habit is quite foreign to that genus, and it 

 is a very abnormal species. 



10. SIEGESBECKIA. 



Siegesbeckia, Linn. Gen. n. 973 ; Bentb. et Hook. Gen. PI. ii. 359. 



A small genus of three species of herbs, one being peculiar to Nile Land, the 

 others are cosmopolitan in tropical and subtropical regions.
