Distribution and Ecology - Distribution. Common on open scrub exposures, collected only from Cerro Neblina.

Discussion:Stegolepis celiae is a well defined species, having the most numerous and smallest spikelets of the section. Contrastingly, its leaves and sheaths are massive, vegetatively resembling most S. pungens of Mt. Duida. Clearly, S. pungens, S. squarrosa and S. celiae form a compact and natural unit. S. neblinensis and S. ptaritepuiensis, mutually closely related, may because of sometimes reflexed sepals be more correctly placed in the Pauciflora.
