when filled, on the 15th December, there was still some water 
present on the 20th, and one had a small quantity on the 26th, 
although no rain had fallen in the meantime. The leaves on a 
plant grown in a moist, shady situation, reached the size of 5 feet 
by 4 feet, which is the greatest size I have seen them reach in the 
Illawarra district.
