Genome designation
HHKK (Genome designation requires reconfirmation)
Chromosome number
Tetraploid, 2n=48
New Guinea
Key characteristics
Short (30-50cm) scrambling herb, pubescent nodes from which roots can readily be formed, prolific stolon production.
Grows on unstable, gravely soils beside rivers. Forest margin so plants receive some sun light during the day.
Potentially useful traits
Pest and disease resistance since field observations in its very moist and humid habitat show very little damage to leaves
Diminutive Oryza with some resemblance to Leersia. Flowers and seeds prolifically in its native habitat but has not flowered when grown outside its habitat.
