Devil's Highway (Roman Britain) Devil's Highway (Roman Britain) The Devil's Highway was a Roman road in Britain connecting Londinium (London) to Pontes (Staines) and then Calleva Atrebatum (Silchester). The bridges at Pontes probably crossed Church Island. At Calleva, the road split into three routes continuing west: the Port Way to Sorviodunum (Old Sarum), Ermin Way to Glevum (Gloucester), and the road to Aquae Sulis (Bath). Its name probably derives from later ignorance of its origin and history, having been replaced for travellers by other roads nearby such as Nine Mile Ride, which runs parallel to the Roman road about a mile away but at
Aphanizomenon flos-aquae (dietary supplement) This linked article is about a single strain of AFA labeled as toxic that has been reclassified. Colony-forming morphology is one of the characteristics of the species "Aphanizomenon flos-aquae"; conversely "Aphanizomenon" are not known to form colonies. Algologists Li and Carmichael noted colony formation, or lack thereof, and other morphologic distinctions when comparing "Aphanizomenon flos-aquae" with "Aphanizomenon". Their genetic comparison of "Aphanizomenon flos-aquae" to other species in the genus "Aphanizomenon" indicates dissimilarity between "Aphanizomenon flos-aquae" and "Aphanizomenon" species. Cyanobacteria have been a staple in the diets of many cultures and have been used for both food and commerce by indigenous
