Bank of the Calcasieu River, West Lake Charles, Calcasieu Parish,

other American lindens T. Cocksii differs in the thicker dark green 
p 
spring, and in the pubescence during the summer on the leaves and branchlets 
of leading shoots in a species which, except when the leaves unfold and the inflo- 
rescence first appears in early spring, is otherwise glabrous. It is most closely 
related to T. floridana, from which it differs in the texture, color, and venation 
of the more finely serrate leaves, in the more compact inflorescence, and in the 
much shorter free portion of the peduncle. I take much pleasure in associat- 
ing with this handsome tree the name of Professor REGINALD WOODHOUSE 
SoMERS Cocks, professor of botany in Tulane University and for many years 
my companion in annual journeys of exploration through the forests of 
Louisiana.
