Along Yucatan streets

All the attached were seen along the streets of Merida, Yucatan. 'Unknown a' herbaceous to small shrub. 'Unknown e' a lawn weed that opens dark blue and fades to white. 'Unknown h', a small shrub. Any help appreciated.

 

Middle two - Commelina sp

 

1. Pseuderanthemum reticulatum?
2. Pedilanthus species

 

That coral flower is gorgeous. Thanks for posting.

 

Identified previously as Pedilanthus, if you were confused by the 1-2 numbering.

 

Thanks for letting me know - a few Pedilanthus are grown in CA....

 

Have been on the road - so a late very big thank you to all. Have not found a flora here yet.
