Description

Item is entitled 'Note on Tetratheca; by Dr Asa Gray'. In an article on the 'Organogenie de la Classe des Polygalinees' in the ANNALES DES SCIENCES NATURELLES number six for 1851, M. Payer discusses the characteristics on which Mr Brown founded his order Tremandraceae. Payer remarks that two of the three characteristics are of no value and the third 'repose sur une erreur' [is based on error]. Gray states that it is unlikely Brown would commit a mistake of this kind, which draws attention to the statement especially as the authority of Mr Steetz is adduced to confirm it. Gray goes on to explain why Payer is mistaken in regard to the character of the order. He also notes that it was De Candolle and Endlicher who made two of the assumptions for the Tetratheca, and not Brown. Page 1 of 2.
