Abstract

Oryza schlechteri has only recently been rediscovered in Papua New Guinea. This species is quite distinct from otherOryza species but resembles closely related genusLeersia in its small panicle and profusely spreading habit. On the basis of spikelet morphology that has previously been used to distinguishLeersia andOryza species,O. schlechteri was compared withO. brachyantha. O. longiglumis, O. sativa, L. perrieri, L. tisseranti, andL. hexandra to clarify its generic position. Results corroborate that the presence of a sterile lemma and a striated spikelet epidermal (abaxial) surface lacking siliceous triads inO. schlechteri allies this species with otherOryza species rather than withLeersia.
