Mr. Bicknell reported the detection by him this season of a plant of Asclepias 

 Cornuti Decaisne, having its leaves in whorls of three, and also of a plant 

 of Silphium perfoliatum L. , with leaves in whorls of three and with 

 a 6-angled stem. Mr. Britton remarked that ^e had observed precisely the 

 same change this year in specimens of Eupatorium teucrifolium Willd. — Sup- 

 pression of Leaflets in Carya. — Mr. Britton showed leaf specimens of a 

 trifoliate form of Carya porcina Nutt. detected in New Jersey, and stated 

 that all the leaves on the tree whence these were taken exhibited the same 

 suppression of the usually two or four additional leaflets. — New Stations. — 

 Mr. Bicknell read a list of new stations for plants belonging to the City's 

 flora. Mr. Rndliin gave White Mills, New Lots, Queens County, as a station 

 for Tripsacum dactyloides L., a plant not reported as belonging to the State 

 flora , and exhibited specimens gathered at that locality. — One person was 

 elected an active member, and two names were proposed for membership.
