numerous pungent scales of the receptacle (whence the generic 
name, éyivos, a hedgehog), which are rigid, green, lanceolate, 
tinged with red and terminated by a black rigid spine. Corolla 
tubular, five-toothed ; stamens included. Style exserted. Ovary 
oblong, crowned with a toothed cup-shaped margin. It flowered 
with us in the open air in July.
