Revision of the Genus Pandanus Stickman, Part 4 
Disposition of Some Later Homonyms 
Harold St. John 1 
Pandanus glauciferus St. John, nom. nov. 
P. glauciphyllus C. B. Robinson, Torrey Bot. 
Cl. Bull. 35: 64, 1908, non P. glaucophyllus 
Ridl., Asiat. Soc Str. Br. J. 41: 50, 1904. 
Under the 1956 International Code, Rec. 73G 
and Art. 73 Note 2, the epithet glauciphyllus, 
differing only in the connecting vowel, and i 
being an incorrect one, is an orthographic error. 
The epithet glauciphyllus must be treated as a 
later homonym and under Art. 64(2) must be 
rejected. Hence, a new name for it is provided. 
Pandanus compressus Martelli, Webbia 1: 363, 
1905; 4(1): table 10, figs. 14-15, 1913. 
P, tetrodon Balf. /. ex Kanehira, Bot. Mag. 
Tokyo 52: 236-239, fig. 70, 1938, avow- 
edly by (Gaud.) Balf. /., based on Bar- 
rotia tetrodon Gaud., non P. tetrodon Ridl., 
R. Asiat. Soc. Str. Br. J. 68: 13-14, 1915.

The genus Barrotia Gaud, was published in 
1841 in the botanical atlas of the voyage of "La 
Bonite.” The new genus was not given a descrip- 
tion, and since it contained three species, the 
genus and its species are invalid and these can- 
not be adopted or transferred. Balfour in 1878 
printed the combination P. tetrodon (Gaud.) 
Balf. f., but did not accept it himself. Hence, 
P. tetrodon Balf. /. ex Kanehira dates only from 
1938 and is a later homonym of P. tetrodon 
Ridl. Kanehira attempted to solve the problem 
by renaming P. tetrodon Ridl. as P. singaporen- 
sis Kaneh. (1938), but this action was illegal, 
and Ridley’s species stands. 
For P. tetrodon Balf. /. ex Kanehira there is 
an available, legitimate name: P. compressus 
Martelli, based on a collection from the Solo- 
mon Islands.
