Tarpum Bay, Eleuthera, Bahamas, Coker gor (type); Cuba, 
Linden 1988. 
This is included by Heimerl in his P. calophylla, in so far as 
Linden’s specimens are concerned, but it is certainly distinct ; 
Wright’s Cuban numbers 2047 and 2042, cited by Heimer! under 
P. calophylla, 1 have not seen. 
4. Torrubia suborbiculata (Hemsl.) 
Pisonia suborbiculata Hemsl.; Duss, Ann. Inst. Colon. Mar- 
seilles, 3:62. 1897. 
A low glabrous shrub, 2.5 m. high or less, with round or 
broadly obovate glaucous leaves less than 4 cm. long, their peti- 
oles extremely short; fruit pulpy, cylindric, red and glaucous 
when ripe, 
Known only from Martinique ; Duss 1467 and 4397. 
5. Torrubia discolor (Spreng.) 
Pisonia discolor Spreng. Syst. 2: 168. 1825. 
Leaves oblong-elliptic, thin, 8 cm. long or less, 2-4 cm. wide, 
obtuse at the apex, narrowed at the base, slender-petioled ; antho- 
carp about 6 mm. long, about one-half as thick as long ; fruit ob-

Haiti (according to Heimerl), and from Cuba, Wright 2040; 
Combs 446 ; Britton & Wilson 72.
