Calyx 5-partite. Corolla rotate, saucer-shaped, or with a short cam- 
panulate tube, 5-lobed; lobes free or connate at their tips, valvate or 
replicate-valvate in bud. Corona double, arising from the staminal- 
column, very variable; outer corona of 5 spreading or erect bifid lobes, 
alternating with the anthers, often adnate to the inner coronal-lobes 
and appearing to form one series with them in the form of lateral teeth, 
or more or less annular or cup-shaped at the base, 10-toothed and often 
with the teeth of two adjacent lobes closer together than are the teeth 
of the same lobe, rarely reduced to a fleshy ring without evident teeth 
or lobes; inner corona of 5 lobes incumbent on the backs of the anthers 
and sometimes produced beyond them into long erect tips, often dorsally 
adnate at their base to the outer corona or connected to it by fleshy 
partitions. Staminal-column arising near or at the base of the corolla ; 
anthers inflexed or incumbent upon the apex of the style. Pollen- 
masses horizontal or ascending, solitary in each anther-cell, with @ 
pellucid margin at their apex, attached in pairs by very sho
