Was visiting a friend's big ass pond earlier today and saw a moss like plant and another kind of plant growing on the pond's edges.
Can anyone help me ID them?

The top plant I have seen before but cant recall the name sorry man.

Top is Azolla caroliniana (mosquito fern), bottom is a duckweed, probably Spirodela polyrhiza (giant duckweed or duckmeat). Both are normally floaters, they were probably stranded by lowered water level or wave action. Azolla can grow for a while on mud but the Spirodela is probably doomed if it remains stranded long.
*EDIT* just noticed you are in the Phillipines. The Azolla is probably A. filiculoides, not A. caroliniana. Are you in a rice-growing area? A. filiculoides is commonly added to rice fields (at least in China) because it is a nitrogen-fixer.

thanks for the quick reply guys!
@noto, yeah, we're in a rice growing part, although this is the first time that i've noticed these kinda plants on the pond. none were floating in the general pond area.
first time i've known that these things are being used as nitrogen fixers, i'll have to mention this to my folks and see if they know about this as they're into rice research.
will try to get more pix, and samples tomorrow... interesting indeed

It does look kind of like Salvinia, but Salvinia has leaves with a crease down the center and a distinctive texture (reminds me of the hook side of velcro). Salvinia leaves also tend to grow in two-row chains, not clumps as with Spirodela.

Just as an aside, Salvinia is a fern, related to Azolla. Neither of them looks very ferny. Spirodela and other duckweeds are flowering plants in the arum family, related to crypts, Anubias, peace lilies, taro, etc.
