dense globose heads at the ends of the branches. Bracts narrowly 
linear ; pedicels pale-green, terete, glabrous, often half as long as the 
flowers. Calyx pale-green, with a very short tube, obsoletely 5-costate ; 
lacinise linear, elongate, 3-nerved, shortly revolute at the apex, papil- 
lose-glandular on the outer side. Corolla lurid, glabrous, virescent on 
the outer side, atro-purple on the inner, often verrucose ; tube campanu- 
late, abruptly expanded into a plano-convex limb ; lobes deltoid, acumi- 
nate, shorter than the tube ; corona slightly fleshy, rose-coloured, pubescent,
