OK - have been searching for orange pea flowers/Fabaceae/Papilionaceae for a couple of years - this seen at Chapultepec Botanic Gardens in Mexico City. The pink flower also seen at Chapultepec; have searched mainly Malvaceae & Portulacaceae but the photos are not so great. The red vine (first 3 pix) was seen February this yearalong the streets of Merida, Yucatan. Any thoughts greatly appreciated.
