Dear Pieter,
	Your note made me go back and re-read Harold Koopowitz' 
account of the genus in his excellent book 'Clivia' (Timber 
Press,2002). This book is a must for Clivia fans and sure to induce 

	He mentions that hybrids between Crypt. and Clivia have been 
tried, but no success reported. Apparently the '3rd' species C. 
densiflorus has never been in cultivation. Oddly both C. densiflorus 
and C. haemanthoides are deciduous unlike C. vansonii or Clivia sp.

	Harold also mentions Cyrtanthus herrei (seen at…) 
. This was originally described as a Cryptostephanus and looks 
remarkably like Clivia caulescens. !

	I grow a 'so called' pink C. vansonii, but the color only 
shows up if the bloom is during a cool period. IN warmer weather the 
flowers are essentially white like the 'typical' form.

	Intriguong plants. Thanks for the info.		Jim W.
