Abolboda grandis Griseb. Linnaea 21: 281. 1848.

Abolboda grandis var. minor Spruce ex Malme, Bih. Sv. Vet.-Akad. Handl. 26: (Afd. III. No. 19):14. 1901.

Type: "In arenosis prope Joden-Savanna (Cordonpad), fl. Novembri Hb. Keg [el], n. 1131." Suriname.

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 oneā€”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.
