Sir, my clarification is for - the leaves all radical and leaves not all radical - should it be be a key or not .
Sir, also request you to have a relook at Samir ji's post and the colour of the cyathia I think red should be E. caducifolia and green should be E. neriifolia. Sorry, but I feel omission of important floral elements will lead to some confusion in the keys. Hope this is taken as constructive criticism! regards, Rashida.
