possibly French Guyana; no reliable information
This small milfoil appeared in the aquarium hobby in 2011 at the latest and was introduced by "manini" on www.aquaticplantcentral.com (erroneously as Myriophyllum sp. "Guinea") and on the blog of Vadim Shmelyov (blog.aquaritet.com). The plant was apparently obtained from a dealer in Japan. We have no certain information about the exact origin of this plant, but the trade name possibly refers to French Guyana. To identify the species, we would need emersed, flowering and fruiting plants.
Myriophyllum sp. "Guyana" is an exceptionally pretty plant novelty. This milfoil is characterised by vivid light green colouration, dense, fairly bushy growth, moderate growth rate and, above all, small size, which makes it well suited for nano tanks. It is reminiscent of the Madagascan Myriophyllum mezianum, but is more densely leafed, grows somewhat faster and also seems to be easier to grow.
For further information, see "Culture".
Myriophyllum sp. "Guyana" is content with medium light intensity. In intense light, however, it develops more beautifully and becomes denser and bushier. In the aquariums at Aquasabi it grows very well in soft water and soil, but has not yet been tested under other conditions.
Like other stem plants, Myriophyllum sp. "Guyana" is easily propagated by head cuttings and partial cuttings.
