Ipomoea indica

Since there are no sepals, it is difficult to state exactly why I take the position that this is Ipomoea indica , but , I have grown and studied Ipomoea indica and Ipomoea purpurea extensively and the corolla in the 1st photo is a ringer for Ipomoea indica, especially the distribution of the pigments and the location of the fading zones... The 2nd photo shows what I have seen Ipomoea indica do many times in the 'way' that it covers the ground but Ipomoea purpurea never seems to do it that same way...even the tri-lobed I.purpurea... I can't prove it but there are aspects that my mind can sense that I cannot put into words and yet, in the depth of my bones , I know that is Ipomoea indica...

I can't say the complete species id . This is one very "uggly" invasive species in Portugal

It looks like Purple Morning Glory...
