Synonym Text: C. breviculmis R.Br. subsp. royleana (Nees) Kük. in Engler, Pflanzenr. IV.20, 38: 469. 1909.
Flower/Fruit: Fl. Per.: April-May.
Type: Syntypes: NW Himalaya, Royle 36, Royle 152 (K!).
Habitat: Mountain slopes from 2000 to 3000 m.
Distribution: Distribution.: From E Afghanistan eastwards along Himalayas; to be expected in Pakistan.
Comment/Acknowledgements: C. royleana belongs to C. breviculmis R. Br. complex. Collectively the complex extends from NW Himalaya to Japan and through Malaysia to Tasmania and New Zealand. Several names have been applied in different parts of this area. C. breviculmis was described from Tasmania. Clarke (1894) and Kükenthal (1909) included C. royleana Nees in Brown's species, latter treating it as subsp. royleana. Nelmes (Mém. Mus. Hist. Nat. Paris, N. Sér., Bot. 4: 83-182, 1955) considered C. royleana to be a good species (see also Fl. Hainanica 4: 343, 1977). Raymond (Mém. Jard. Bot. Montréal 53: 1-126, 1959) united it with C. leucochlora Bunge, originally described from China (see also Fl. Tsinglingensis 1: 249, 1976). Koyama in H.Hara, Stearn & L.H.J. Williams, Enum. Flow. Pl. Nepal (1978) and Kern & Nooteboom in Fl. Malesiana (1979) reverted back to the collective treatment; Dickoré (1995) does not list the species. The species complex is much in need of an overall revision.
