This is another introduced species, flowers not as lovely as the previous one, and also quite invasive. However, i still don't know the name, probably this is Mikania micrantha.
I found this single petal Clitoria ternatea in a second growth forest when we passed to the other side of the ravine. I very well know it being used favorably these days in Edible Landscaping. There is a multipetal of this too. They are used in salads and also source of color for making blue rice, while the blended juice is also a good colorful thirst quencher. There are resorts and restaurants that cultivate this for their commercial business.
This Ipomoea pes-caprae is a cousin of the sweet potato . It is covering the smaller bushy weeds near the roadside. I wonder if maybe some butterfly larvae are eating the leaves. If time allows, i will observe them for longer periods.At the moment, i can only take its photo.
