Origin o/ Ginothera Lamarckiana De Vries. 235 



and plate in " The Floral Magazine " is tiiat fLirnished by a very 

 important sheet in the Gray Herbarium of Harvard University. 

 This sheet I shall again describe and figure in the hope that it may 

 lead botanists to make a persistent search for herbarium material 

 that may throw further light on the problem. 



Fig. 1. Sheet in the Gray Herbarium of Harvard University. KnCEiwtlicva 

 grown by Dr. Asa Gray at Cambridge, Massachusetts, in 1862 and probably 

 derived directly or indirectly from the cultures of Carter and Company, of 

 London, which were distributed under the name Lamaychiana. This plant 

 differed from CBnotheya Lamaychiana De Vries in the longer internodes of the 

 inflorescence, in the larger and more leaf-like bracts, in the more slender form 

 of the buds, in the more attenuated sepal tips, and in the longer seed-capsules. 



The sheet in the Gray Herbarium (Fig. 1) holds specimens of 



a plant " Oe, Lamarckiana" grown in Cambridge, IVIassachusetts, in 



1862 by Dr. Asa Gray. From records upon the sheet' it appears 



quite certain that Dr. Gray received seeds from William Thompson 



' See Davis, American Naturalist, vol. 46, p. 417, 1912.
