Aquatic plant

Hanguana malayana

Description:

Spotted in Banggalau Lake, Brgy. Luga, Sta. Teresita, Cagayan. Video shows the canoe that is the only way to get through these aquatic plants and the inflorescence are shown at 2:49 & 2:57.

Habitat:

The linear leaves are clustered at the base of the stem and have long prominent longitudinal veins, with less prominent secondary veins that run perpendicular to the midvein. Young leaves have long, branched hairs on their surfaces that rub off in older leaves. Flowers are produced in a n extensively branched inflorescence. As is typical for monocotyledon flowers, Hanguana malayana has 3-parted flowers, with 6 undifferentiated tepals. This species is dioecious, meaning that the pollen and ovules are produced in separate flowers borne on separate plants. Both pistillate (ovule producing) and staminate (pollen producing) flowers have structures called nectaries in which nectar is produced. In the pistillate flowers the nectaries are present in sterile stamens and in staminate flowers the nectaries are present in the sterile ovary. The fruit is a one seeded berry. -http://ntbg.org/plants/plant_details.php?plantid=5719

Yeah, it was quite chancy but decide to take the chance, anyway there's the canoe I can grab on to. They said it's 2-3 person deep (about 15'). We were in the area to explore caves for the municipality and they ask us to take photos of the lake that they plan to promote for bird-watching. There were only two canoes available, so room for only two photographers, so...

It definitely was fun & exciting! BTW, we did recommend to the municipality that PFD's be provided for the future visitors!

Mmm! Not sure if I would have gone witout a lifejacket if I could'nt swim, although I'm guessing the water was'nt actually that deep. Looks an amazing place, were you actually looking for something in particular or having a general explore? You might want to take something a little more appropriate with you next time you plan to travel in a leaky boat : ) Looks great fun, all part of the experience.

Thanks for the ID, Viv!
I was a little hesitant to ride these canoes because I can't swim but couldn't pass up the opportunity so I just kept bailing water as it went over the mud patch used at the front of the canoe. Who said, "No fear?"

There was a plant similar to your spotting growing in a wetland area in the south of Thailand that I visited earlier in the year, so I found this plant mentioned in a study -http://www.arcbc.org.ph/wetlands/thailand/tha_thanoi.htm. Hope it is of some help in identifying yours.
Great video ..
