Pisely allied to C. sericeus Burm. and C. Schimperi Boiss., 
though with its hirsute ovary it is evidently not identical with 
the preferable course. Bot species above named have the 
curious plicate leaves of the Oman plant—this plication being a 
method, apparently, whereby the area of leaf exposed to the direct 
rays of the sun is reduced—but the habit of both is different. 
Moreover C. sericeus has a very short tomentum, smaller and sessile 
or shortly petiolate leaves, and larger globose capitula ; ; the leaves 
. Schimperi being longer and broader, and the caudate sepals 
nearly twice as long as those of the plant here described. 
Hildebrandtia Vatke (Tab. 402 a & e).—This genus has recently 
been shown by Dr. Hans Hallier (Engler, Bot, Jahrb. xxv. p. 510)
