Stipagrostis plumosa
This grass species was noted in the upper, rocky area of Karkur Talh, growing among rocks following the rains of 2005. It was common in the area, but not noted anywhere else in the rain affercted valleys. The species is short, maximum 20 cm in height, and all observed specimens supported fully formed garlands. A single specimen was seen in upper Karkur Talh in 2006 in the rain affected area, and another one (identification doubtful, possibly Aristida mutabilis) in the upper reaches of Wadi Handal, where it must have been remnant vegetation of the previous years' rains.
The species was also observed growing in a sand filled ravine in a wadi in the northern Gilf Kebir (parallel and to the east of the lower section of Wadi Abd el Melik) in March 2007, at the same time when growth spurred by a small local rain was observed in a western tributary of Abd el Melik. The species was noted in a similar environment, but in a dried state in Wadi Hamra.
