Maybe Aerangis sp. Possibly Aerangis biloba? http://www.google.co.uk/imgres?imgu...qagB&esq=1&page=1&ndsp=23&ved=1t:429,r:18,s:0 http://www.google.co.uk/imgres?imgu...chagB&esq=1&page=1&ndsp=23&ved=1t:429,r:7,s:0 http://www.orchidspecies.com/orphotdir/aerangbiloba.jpg
I agree with Aerangis, but I don't think biloba. Possibly articulata, or maybe a hybrid, in which case I can't identify. Is there anyway to check with the grower?
