In my eyes, Utricularia juncea is the most beautifull Utricularia one can find in Fr.Guyana.

Of course this is a personal opinion, but truly, it's a special experience in itself

to find this plant blooming in Nature : they are rather tall, about 40 to 50cm in some biotopes, 

and they shine with an intense yellow and with a kind of glowing from inside if it's a sunny day :

These plants need open space to grow.

>>>>>> ESPACE - GRIS FONCE <<<<<<

In savanas it's not a problem, but in forests, they will grow only in such places :

the place has to be wet all year, like the sides of a littles stream,

and must be sunny to fit the plant's needs.

U.juncea grow in the most wet parts of the biotope : 

here they grow directly in the middle of the stream, wich is very slow indeed.

The substrate is made of laterite, wich is very muddy in these kind of places . 

This ground layer is covered with a thin layer of brown algae.

Over these, a layer of water of 5cm, wich stream slowly over the plants.

The flowers are easy to recognize : the lower lip is covered with an impressive bulb,

wich make the corolla appear pretty big in size and give it it's particular aspect :

The inflorescence is rather thick, to widstand the winds, and the stream of the water.

>>>>>> ESPACE - GRIS FONCE <<<<<<

Most of the plants wich live in relatively fresh biotopes, like forest biotopes, 

appear to have 3 or 5 flowers open at the same time,

while plants from the warmer savanas have 1 to 3 flowers open simultaneously only.

This plant love to grow together with big, tall grasses.

>>>>>> ESPACE - GRIS FONCE <<<<<<

I never found them in seeds, but as for so many plants, at that stage of their live,

the seedpods are supported by the dry debries of a rotting plant,

and the seeds have been dispersed since a long time.
