• Each megaspore was first photographed in dry state under reflected light and its characters were noted. After photographing in dry state, the megaspore was transferred to a covered petridish and was oxidised with nitric acid, sometimes using potassium chlorate. The oxidised material was digested with potassium hydroxide and cleaned with water. Observations were made at frequent intervals during this progressive maceration and photographs were taken, as and when felt necessary, by transmitted light.
