Involucri multiseriati (4-6), phyllariis imbricatis inrequalibus glabris stramineis, interi- 

 oribus lineari-oblongis obtusis margine scariosis, exterioribus gradatim brevioribus ellipt-

Distrib. Endemic. 



Another species hitherto only known from Dr Nimmo's fragmentary speci- 

 mens, and described by Oliver and Hiern (loc. cit.). Like H. rosulatum, 0. and 

 H., it is found at high altitudes growing in sheltered spots, and it appears to be 

 endemic in Socotra, and is very distinct from any known form. Our specimens 

 show leaves generally more obtuse than those on Nimmo's plant.

Nom. Vern. Sebenham (B.C.S.). 



Socotra. On the higher parts of Haghier. B.C.S. n. 406. Schweinf. n. 

 628. 



A very beautiful aromatic species. It is quite distinct from any known 

 form. H. Nimmoanum, 0. and H., which grows with it, is perhaps as near an 

 ally as any other species.
