Hypochaeris kadicata L. — In Dr. Britten's recently pub- 

 lished " Manual of the Flora of the Northern States and Canada," 

 the habitat of this plant is given as " waste places, Long Island to 

 New Jersey." Last summer it was discovered to be well estab- 

 lished in three localities on Staten Island, namely on Todt Hill, 

 near Egbertville, and in the grounds of the S. R. Smith In- 

 firmary. In the last named locality it persists in spite of the 

 mowing machine. An interesting habit of the plant is the closing 

 of its flowers early in the afternoon, even on bright sunny days.

PROCEEDINGS OF THE CLUB 



Wednesday, January 29, 1902 



The meeting was held at the Museum of the New York Botan- 

 ical Garden; seventeen persons present, Dr. MacDougal in the chair. 



The first paper was by Dr. Britton, entitled " Notes on the 

 Crassulaceae," and is to appear in print, being a part of a contri- 

 bution toward the projected Flora of North America. Remarks 

 followed by Dr. C. C. Curtis, Dr. Rydberg, Dr. Small, Dr. 

 MacDougal and Mrs. Britton. The distribution of the Cras- 

 sulaceae was commented on, Dr. Britton speaking of the iso- 

 lated colonies of high mountain species, which seem to have con- 

 tinuously interbred and in which this process seems responsible 

 for the development of specific characters. 



The second paper, by Professor F. S. Earle, entitled " New 

 Genera of Fungi," founded on representatives from California and 

 New Mexico, will soon appear in the Btdletin of the New York 

 Botanical Garden. 



Professor Earle also exhibited a rosebush from under glass at 

 the Garden, the roots of which had been attacked by a fungus 

 now under examination. The mycelium is abundant in the 

 fibrous roots, also in the bark and cambium immediately above 

 ground, and has caused a sudden yellowing and drooping of the 

 leaves. The rosebush shown had been artifically infected from 

 cultures of a fungus taken from similarly diseased bushes grown 

 in New Jersey.
