Botanical Notes, 



Ttibniar Floivers in Rudbcckia. I have lately had handed to 

 me a flower of the Rudbcckia Jiirta^ in which the rays instead of 

 being flat are all tubular. The plant grows here hi Concord, it 

 had eight or ten flowers and all the rays were like the specimen 

 given me. The tubular flowers were of the light color of the un- 

 derside of the rays, while the opening at the end was bright yel- 

 low, a line or vein being on the centre of the upper side where 

 the rolled rays seemed to join. The flower looked very much 

 like the hub and spokes of a wheel. A. W. HoSMER.

Progress at Broivn University, ]?otany is looking up at 

 Brown University. At its last meeting, the Corporation elected 

 Mr. James L, Bennett Curator of the Herbaria, and Prof. H. 

 C. Bumpus assistant in Biology. We have some hopes, too, 

 of new and better accommodations for the herbaria and labora- 

 tory. We greatly desire to strengthen our present collections 

 and to create an economic museum. In the hope that some 

 friend may see this and aid us, I send you this brief note. 

 P>L]its, fibres, fabrics, drugs ; nothing vegetable will be alien to us. 

 We ask the good will of the fraternity. , W. W. Bailev.
