Sepals 4, connate below in a tubular or infundibuliform tube, valvate in 

 aestivation ; lobes deciduous ; tube more or less persistent. Petals or 4, 

 inserted in the mouth of the calyx-tube. Disk usually distinct, lining the

 slightly exceeds the calyx-tube ; filaments free. Ovary cylindrical linear 

 oblong or ovoid, on a long gynophore, 1-celled or 2-celled owing to the meet-
