376 Gruenberg and Gies : Notes on " bastard" logwood 



of Haematoxylon cainpccJiianum, notwithstanding the slight mor- 

 phological differences that distinguish it from the " red logwood " 

 and " blue logwood." The differences in the floral organs between

 William Fawcett near Morant Bay, Jamaica, show all the morphological differences 

 that have been observed in the flowers of three varieties : a, " blue logwood." b, "red 

 logwood." c, "bastard logwood." 



The petals are widest in the blue and narrowest in the bastard. 



The pistil of the blue is thicker than that in the red and the bastard. The style in 

 the bastard is slightly curved. 



In the bastard the stamens are smaller than in the others, and there is less differ- 

 ence between them. 



It does not appear from the data at hand that the differences noted exceed the 

 ordinary individual variations for the species of Haematoxylon. 



the three varieties are shown in figure 2, which was made from 



drawings sent by Mr. Fawcett, of the Jamaica Botanical Gardens. 



That there are species which are not at all distinguishable from 



one another externally, but which vary in their physiological prop-
