 (1893). /. HystrixYLaWA. I.e. 



I have not seen the specimen of Bohm's, on which Hallier based 

 /. Hi/strix, but from the plants which he assigns to this species in 

 Bull. Herb. Boiss. vii. 58, iuchidiiig one collected by 8coit Elliot in 

 the Shiie Highlands (no. 8639), there can be no doubt as to their 

 identity with the West African /. Welivitschii. Hallier says of 

 1. Hystrix, " praecedeuti " (i.e. /. Welwitschii) " valde afifinis, sed 

 multo humilior densiusque foliosa," but the Shire specimen is 

 larger than the average of the Angolan, and is certainly not more 

 laxly leaved.
