edition of his Flora de Filipinas he correctly reduced in the 
second edition to the widely distributed Barringtonia racemosa 
Blume. The species occurs throughout the Philippines along 
small streams and in thickets near the sea, never extending 
far inland, and is commonly known as putat. 
Illustrative specimen from Taytay, Palawan, May, 1913 (Mer- 
rill: Species Blancoanae No. 410). 
RHIZOPHORACEAE 
CERIOPS Arnott 
Rhizophora candel Blanco Fl. Filip. (1837) 396; ed. 2 (1845) 277; ed. 3, 
2 (1878) 150, t. 415, non Linn.=CERIOPS TAGAL (Perr.) C. B. Rob. 
(C. candolleana Arn.). 
Blanco’s description applies unmistakably to Ceriops, and to 
the form now known as C. tagal C. B. Rob., which was originally 
described from Philippine specimens. It occurs along muddy 
shores throughout the Philippines. 
Illustrative specimen from Laguimanoc, Tayabas Province, 
Luzon, March, 1917, here known as tavgal (Merrill: Species 
Blancoanae No. 1047). 
RHIZOPHORA Linnaeus 
Rhizophora longissima Blanco Fl. Filip. (1837) 398 (sp. nov.); ed. 2 
(1845) 278; ed. 3, 2 (1878) 151=RHIZOPHORA MUCRONATA Lam. 
This species occurs with Rhizophora candelaria DC. (Rf. 
conjugata) and is widely distributed in the Philippines. It 
can be readily distinguished from that species by its long pe- 
duncles, which are several-flowered. In my previous paper on 
Blanco’s species I followed Fernandez-Villar in reducing Rhizo- 
phora longissima Blanco to R. conjugata Linn., but Blanco’s 
description of the inflorescence applies unmistakably to Rhizo- 
phora mucronata Lam. Rieeophors longissima Blanco is not 
listed in Index Kewensis. 
Illustrative specimen from Taytay, Palawan, May, 1913 (Mer- 
rill: Species Blancoanae No. 409). 
Rhizophora mangle Blanco FI. Filip. (1837) 397; ed. 2 (1845) 278; ed. 3,

Fernandez-Villar reduced Rhizophora mangle Blanco, non 
Linn., to R. mucronata Lam., in which I followed him in my 
previous paper on Blanco’s species. An examination of Blanco’s 
description, however, shows conclusively that he described R.
