KÜKENTHAL placed S. longibracteatus with doubt in sect. Nudicaules. In my opinion its close affinity to S. curvulus is evident. According to KÜKENTHAL S. neoguinensis is close to S. curvulus. The description agrees in almost every detail with that of S. longibracteatus. I do not hesitate to unite S. neoguinensis with S. longibracteatus, although the spikelets in the former are somewhat larger.
