Melchora Aquino de Ramos (1812–1919) was a Filipina revolutionary who became known as "Tandang Sora" ("Elder Sora") because of her age. She is also known as the "Grand Woman of the Revolution" and the "Mother of Balintawak" for her contributions.

Vanda sanderiana, value above, scientific name below.

Vanda sanderiana is a flower of the orchid family. It is commonly called Waling-waling in the Philippines and is also called Sander's Vanda, after Henry Frederick Conrad Sander, a noted orchidologist. The orchid is considered to be the "Queen of Philippine flowers" and is worshiped as a diwata by the indigenous Bagobo people.

In 2004, there had been a motion in the House of Representatives of the Philippines to declare the "Waling-waling" as the country's national flower, replacing the Sampaguita. In 2013, a bill was passed by the Philippine Senate declaring the Waling-waling as a national flower alongside the Sampaguita. However, the House Bill 5655 was vetoed by President Aquino citing that there are other means to promote the protection and preservation of the Waling Waling Orchid without declaring it a second national flower.
