118 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [Vol. 8, No. 2 



The distribution of the plant is likewise interesting; it was observed only 

 along this stream in that portion near our savanna camp, downstream for perhaps 

 a couple of miles. In this expanse outcrops and knobs of the ancient granitic 

 basement rock abound but as these outcrops disappear downstream, this plant also 

 disappears. Whether there is any real correlation between the two distributions 

 was not determined but the apparent restriction of the plant may very well be due 

 to edaphic factors.
