Unusual flowers?

I found these flowers unusual when I first saw them bloom. Of these two I am told that the Jasmine flower in the first image is Adukku Malli. One person even told me it is Mysore Malli but a single flower was as big as a small rose. The regular sized Jasmine buds are in the background.



The second image shows you white Arali flowers blooming from a bunch of red Arali flowers. Note that it is from the same plant. The whites aren't pure whites as they have a tinge of pink to them. You can see two in the foreground and two in the background but they are from the same bunch that produces only red flowers. This happened only once.
