that grows from an enormous root and bears spiny pods con- 

 taining large oval or elliptical seeds. This root was on the 

 side of a grassy hill and had become exposed. The inner part 

 had decayed leaving a shell about one and a half inches thick 

 surrounding a cavity something like 30 inches in its long diam- 

 eter by perhaps 12 or more the other way which had at one 

 lime been occupied by a swarm of bees, as evidenced by the 

 scraps of comb clinging to its inner surface. Its occupation 

 by the bees seems to have had no detrimental effects on its 

 vitality, as there was a more or less vigorous vine growing 

 from it. — Ceo. L. Moxlcy, Los Angeles, Calif. 



Ayrshire Rose in Washington. — While attending high 

 school in Vancouver, Washington in 1915, I became interested 

 in a white rose that baffled all my efforts to determine it. 

 There were none like it in the gardens of the locality, so I as- 

 sumed that it was native, for it looked like a w^iite form of 

 Rosa pisocarpa in some respects. While I have, at present, 

 onlv the specimens collected from a large bush which grew 

 in low ground about three miles north of Vancouver, I have 

 the distinct recollection of seeing a smaller bush growing in 

 Vancouver a few blocks west of the High School. This one 

 was on a parking. This year I went over my herbarium of 

 Washington specimens, and I became curious again about tiie 

 w^hite rose ; so I compared notes w^ith Professor Nelson oT 

 Salem. Oregon, who thought it might be the same that he had 

 collected at Salem. His rose, however, was double. I sent 

 a speciment to him. but it was entirely new to him, so he sent 

 it at once to Dr. Rydberg who wrote that it seemed to be the 

 Avrshire rose, whicli is common in cultivation in England 

 and which is supposed to be a fr)rm or hybrid of Rosa arren- 

 sis. a native of England and Western Europe. My specimens 

 appear to be only ones that have been collected from bushes 

 naturalized in this country. — R. V. Bradsha^i', Eugene. Ore.
