CASUARINACEAE 
CASUARINA Linnaeus 
CASUARINA EQUISETIFOLIA Linn.; Blanco FI. Filip. (1837) 661; ed. 2 
(1845) 460; ed. 3, 3 (1879) 67. 
The species was correctly interpreted by Blanco, but Fer- 
nandez-Villar erroneously reduced the form described by Blanco 
to Casuarina sumatrana Mig. Linnaeus must be cited as the 
author for the species as well as the genus, although Forster 
is usually given as the author of the former. The combination 
Casuarina equisetifolia (equisefolia) Linnaeus appears in Amoen. 
Acad. 4 (1759) 143, the species being typified by Casuarina lito- 
rea Rumph. Herb. Amb. 3, pl. 57. It is common and widely 
distributed in the Philippines along the seashore and extending 
far inland in open river valleys, reaching an altitude of at least 
500 meters. It is widely known as agoho. 
Illustrative specimen from Isabela Province, Luzon, June, 
1913 (Merrill: Species Blancoanae No. 595). 
PIPERACEAE 
PIPER Linnaeus 
Piper parvifolium Blanco Fl. Filip. (1837) 23 (sp. nov.) ; ed. 2 (1845) 17; 
ed. 3. 1 (1877) 32=PIPER RETROFRACTUM Vahl. 
The species is common and widely distributed at low altitudes 
in the Philippines and is especially abundant in those provinces 
from which Blanco received most of his botanical material. It 
is still known in the vicinity of Manila as sabia, the native name 
cited by Blanco. sae 
Illustrative specimen from Angat, Bulacan Province, Luzon, 
September, 1913 (Merrill: Species Blancoanae No. 523). 
PIPER NIGRUM Linn.; Blanco FI. Filip. (1837) 21; ed. 2 (1845) 16; ed. 
3, 1 (1877) 29, t. 77. . 
The Linnean species was correctly interpreted by Blanco, the 
Philippine form being referable to the var. triotiewm C. DC. The 
pepper plant is cultivated only to-a limited extent in the Philip- 
pines, not on a commercial scale, and is known as pimienta 
(Spanish), and malisa (Tagalog). 
. Illustrative specimen from Balayan, Batangas Province, Lu- 
zon, September, 1914 (Merrill: Species Blancoanae No. 585). 
Piper obliquum Blanco FI. Filip. (1837) 22; ed. 2 (1845) 16; ed. 3, 1 (1877) 
30, non Ruiz & Pav.=PIPER CORYLISTACHYON (Mig.) C. DC... 
There is no doubt as to the correctness of Fernandez-Villar’s | 
reduction of Blanco’s Piper obliquum to P. corylistachyon C, DC.
