 in basin caulis ascendentia, demum in caulina mutata. Bractese venosce, 

 coriacece : inferiores Jioribus longiores. Flores in fasciculis subsessilibus, 

 intra bracteas axillaribus, dispositi, purpurei, ad marginem amoene cyaiiei. 

 Calyces coriacei, sepalis iialdb acuminatis, ampliaiitibus . Corolla calyce
