86 Beal : Notes on Cabomba Caroliniana 



seasons, I have heard of spikelets of Eragrostis major containing 

 as many as 50 florets on an axis 20 mm* long. 



The spikelets of Chamaeraphis {Set arid) viridis (L.) Porter, 

 bear 1—5 persistent, awnlike, barren branches or bristles. 



In October, 1898, in rich ground, I found several thrifty 

 plants of this species, in which a considerable number of the upper 

 bristles bore at the apex, each a spikelet, and in one case, a spike- 

 let was borne on the side of a bristle about two-thirds the dis- 



tance from the base to the top (Fig. 2). The specimens with 



spikelets on the bristles confirm the statement, if it needs any 

 further confirmation, that these bristles are actually branches and 

 not mere hairs. 



Notes on Cabomba Caroliniana A, Gray 



By W. J. Beal 



Perhaps it is ten years ago that I bought some small plants of 

 this species of the water-lily family and placed in a small pond in 

 the botanic garden. Nothing seemed to come of them, and they 

 were given up for lost. In four years, there appeared some plants 

 in considerable quantity in the center of a larger pond below and 

 connected with the one where the Cabomba had been planted. I 



was 



of the long-lost Cabomba. It spreads, and is inclined to take com- 

 plete possession of the lower ground, mixing in and crowding the 

 water lilies which were previously well established.
