Andrea B. Posted April 14, 2016 Share Posted April 14, 2016 Another new one for me, Dave. Very elegant flower which is striking in the UV with the bright center against the dark. Link to comment
DaveO Posted April 14, 2016 Author Share Posted April 14, 2016 Yes, I was also surprised by the UV bright centre, none of the other taxa in this family which I have taken respond in the same way. We will try to find other Crowea to see how general it is. Dave Link to comment
