- Aratus applied the mythical name Ἠριδανός (Eridanos) to this constellation although many other authorities, including Ptolemy in the Almagest, simply called it Ποταμός (Potamos), meaning river. Eratosthenes had another identification: he said that the constellation represented the Nile, ‘the only river which runs from south to north’. Hyginus agreed, claiming that the star Canopus lay at the end of the celestial river, in the same way that the island Canopus lies at the mouth of the Nile. However, in this he was wrong, for Canopus marks a steering oar of the ship Argo and is not part of the river. Hyginus had evidently misunderstood a comment by Eratosthenes, who had simply said that Canopus lay ‘beneath’ the river, meaning that it was at a more southerly declination.
- Rubus armeniacus (Wikipedia)
Rubus armeniacus, the Himalayan blackberry or Armenian blackberry, is a species of Rubus in the blackberry group Rubus subgenus Rubus series Discolores (P.J. Müll.) Focke. It is native to Armenia and Northern Iran, and widely naturalised elsewhere. Both its scientific name and origin have been the subject of much confusion, with much of the literature referring to it as either Rubus procerus or Rubus discolor, and often mistakenly citing its origin as western European. Flora of North America, published in 2014, considers the taxonomy unsettled, and tentatively uses the older name Rubus bifrons.
