New Providence, Bahamas, Cooper 18 and 23 ; Curtiss 126 ; Coker 

 j and 2j2 ; Brace 16 j, 183 and 180 ; Britton & Brace ij6 and 484. 



2. Torrubia rufescens (Griseb.). 



Pisonia calophylla rufescens Heimerl, Bot. Jahrb. 21 : 626. 



1896. 

 Pisonia rufescens Griseb.; Heimerl, loc. cit., as synonym. 



Leaves thick, flat, obovate, finely and densely tomentulose 

 beneath, rounded or truncate at the apex, cuneately narrowed at 

 the base, the stout petioles I — 1.5 cm. long. 



Cuba, Wright 464. 



3. Torrubia Cokeri Britton, sp. nov. 



Glabrous, the twigs gray. Leaves firm, obovate, 8 cm. long 

 or less, 3—4 cm. wide, rounded at the apex, narrowed or some- 

 what cuneate at the base ; petioles stout, about 1 cm. long ; flow- 

 ers sessile, the perianth and corymb-branches minutely tomentu- 

 lose ; staminate perianth about 3 mm. long, bluntly 5-toothed, 

 about one-half as long as the stamens. 



Tarpum Bay, Eleuthera, Bahamas, Coker 401 (type); Cuba, 

 Linden ip88. 



This is included by Heimerl in his P. calopliylla, in so far as 

 Linden's specimens are concerned, but it is certainly distinct ; 

 Wright's Cuban numbers 20+1 and 2042, cited by Heimerl under 

 P. calopliylla, I have not seen. 



4. Torrubia suborbiculata (Hemsl.) 



Pisonia siiborbiculata 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 1 46J and 4391. 



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- 

 long, red, the pulp rather thin. 



The type is from Jamaica ; the species is also known from 



Haiti (according to Heimerl), and from Cuba, Wright 204.0 ; 



Combs 44.6 ; Britton & Wilson J2.
