An unreported host of Phoradendron 



Louis C. Wheeler 



Of the numerous hosts for the several species of Phoradendron 

 (Mistletoe), some of which are rather omnivorous, no species 

 of Adenostoma seems ever to have been reported as a host. I 

 have collected Phoradendron villosum Nutt. var. rotundifolium 

 Trelease (if the var. is to be recognized) twice on Adenostoma 

 fasciculatum H. & A. : First, Gleason Canyon at Aliso Canyon 

 Road, Alt. 3,000 ft., San Gabriel Mrs., Los Angeles Co., Calif., 

 #610, Apr. 10, 1932. Several infested individuals of the Adeno- 

 stoma were seen. Specimens are in my herbarium and the her- 

 baria of California Academy of Sciences and Pomona College. 

 Second, two miles above mouth of Agua Dulce Canyon off 

 Soledad Canyon, Alt. 2,200 ft., Los Angeles Co., §1484, Feb. 23, 

 1933. Only one specimen was found and that is in my herbarium. 

 These two stations are only about 10 miles apart. In both places 

 this Phoradendron commonly infests Quercus dumosa Nutt. ap- 

 proaching var. turbinella Jepson. While this area is in the cis- 

 montane drainage it has the desert influence evidenced by Junip- 

 erus calif ornica Carr.

AZOLLA IN NEBRASKA 

 N. F. Peterson 



Recently I read the article by Mr. R. H. Torrey, Azolla 

 caroliniana survives in Queen's kettle-hole pond, (Torreya, 34, 

 page 11) and it occurred to me that another case of Azolla per- 

 sisting for a long time where one would scarcely expect to find 

 it might be of interest. Last summer driving south from Thed- 

 ford I stopped to fill the radiator at the Dismal River. To my 

 surprise the pailful of water from the edge of the river was full 

 of Azolla. 



This was probably not far from where Dr. P. A. Rydberg 

 collected Azolla caroliniana at Plummer Ford 41 years ago. So 

 far as I know Blue Creek in Garden County is the only other 

 locality in Nebraska where Azolla has been reported to occur 

 as a native plant.
