increased by cuttings of the half- 

 ripened shoots, or by layering the 

 ripened stems. The species figured 

 here, A. Ooldieana, is a remarkable 

 native of old Calabar, West Africa. 

 It has a swollen woody root-stock, 

 from which the stems shoot up 

 annually. The large leaves are 

 heart - shaped, and the enormous 

 flowers (over a foot across) are of 

 brownish - red colour, mottled with 

 yellow, while the distended throat 

 is streaked with red and creamy

This plant rarely flowers, but when 

 it does it excites attention. It must 

 be kept dry when in a dormant

 freely as growth commences and 

 increases. The atmosphere also 

 should be humid, and the night 

 temperature should not fall below 

 65° to 70° F.
