Lanjouw has presented evidence to show that a third inner membranous sepal is present in flowers studied by him, of Abolboda grandis, presumably collected in coastal Suriname savannas. A year and a half later,6 he restates his original proposition.
I have examined with some care young flowers (pre-anthesis) in some 20 sheets of A. grandis,, but have found the third sepal present only in one—and that specimen from Suriname. It is suggested that the third sepal is not characteristic for the species as a whole, but may be found in local Suriname populations.
