Probably over-looked when not in flower.  Previously known as Sempervivella acuminata.
Collected by my team during the Southampton University Ladakh Expedition 1980 at Rangdum, Suru valley – 4000m S-facing scree, dry sandy, fragmented mica, pinkish-red stem, pink-rted markings on undersides of white petals, pale yellow ring inside corolla, to 9cm.
Members of the Southampton University Zanskar Expedition 1981 found this at Padam, 3650m, dry, sandy/silty, mica-rich ‘soil’ among boulders and scree on sparsely vegetated slopes.
The common Chikor patridge is said to be fond of its leaves.
Flowers of Himalaya record it from rocky slopes in dry areas only @ 2400-4500m from Afghanistan to Himachal Pradesh.
Stewart recorded it as common in Kashmir and also Ladakh @ 2400-4200m in bare, sunny, stony soil.
Flora of Lahaul-Spiti found it frequent in rock crevices and stony glacial moraines at Khoksar.
Last time I was in Lahoul I remember it abundant on bare ground at Chatru.
The following and nearby pages show the plant in Baltistan:
