"Delei Valley. 26 El N. 96 37 E. Alt. .13000 ft. Flowers pale pink, rather large in tight heads. A prostrate species growing on slabs of rock or on grassy ledges of cliff. The truss carries as many as 12 flowers, whose large expanded limbs, tightly pressed together (owing to the extreme shortness of the pedicels) make the head conspicuou^. The pedicel has a few scattered scales. Calyx generally 3- or 4-lobed with a few odd scales and ciliate margin. Corolla glabrous except the tube, which is lined with soft ^white hairs from tae summit to within a very short distance of the base where it is slightly expanded to embrace the ovary and the insertion of the* stamens. There are only six stamens with glabrous filaments about half as long as the corolla tube, the ?anthers *arange brown. Ovary more or less closely lepidote, style crimson, shorter than ovary, crowned by a large lobulate green or cream coloured stigma.
Th-e 16aves are large for tne size of the plant, dark green above, rought with the remains of old scales, and witn tne veins sunk, lowerisurface rusty yellow, with a thick layer of loose overlappirg scales. A beautiful rock plant. 17/6/28. Ward 8337".
