KAS Week DS_051012_04 Ipomoea: Ipomoea from Kas - proper id please.
this is Ipomoea barlerioides (Pink morning glory)
I think this one looks different than Ipomoea barlerioides, but lets wait for more inputs.
This is surely not I. barlerioides. Plant description would have helped. This seems to be a large climber with large cordate leaves that may have been found near Kas lake on large shrubs. This would be Argyreia involucrata. Ipomoea barlerioides is a prostrate herb found on lateritic plateau. It has small (3 cm) hairy leaves and the flowers have a very slender tube.
Argyreia sericea probably as leaves appear broadly ovate
Calyx above the flower does not match with images at Argyreia sericea
