10324. SoLANUM COMMERSONI. Aquatic potato. 



From Marseille, France. Received thru Dr. E. Heckel, January 2, 1904. 



' ' Tubers of the so-called ' aquatic potato ' of Uruguay. This species from Uru- 

 guay is being experimented with by Doctor Heckel, of Marseille, who is breeding it 

 with the ordinary potato and finds that it gives successive crops on the same soil 

 without the necessity of replanting. It also gives abundant foliage, which bethinks 

 may be used for green forage. He further points out that the bitter flavor of the skin 

 will protect the potato against the depredations of subterranean enemies. Its keep- 

 ing qualities during the winter are good. Very little rot appears, and rats are not 

 fond of it. The special point, however, to be emphasized in connection with this 

 new species is that the diseases of the potato do not attack it. One difficulty in its 

 culture consists in the necessity of working over carefully the soil to an unusual 

 depth, because the tubers are deeply buried in the soil. It flowers abundantly, 

 beginning in June and ending in September, the flowers having a perfume similar to 

 that of jasmine. Their odor on a hot day is perceptible for several meters. Plant-
