18 ENUMERATION OF PHILIPPINE PLANTS = 
“Hab. in insula Luzon” Presl; the record was apparently based on a 
South American specimen erroneously localized as Philippine. 
PIPER CLYPEATUM Wall.; C. DC. Prodr. 16* (1869) 878; F.-Vill. Novis. 
App. (1880) 176. P 
PIPER MANILLANUM Mig. Syst. Pip. (1843) 339. 
“Manille, Gaudichaud 1836” de Candolle; the “Philippine” specimen was 
probably from Singapore or Penang rather than from the Philippines. 
PIPER GRANDE Vahl; Opiz in Pres] Rel. Haenk. 1 (1828) 156. 
“Hab. in insula Luzon” Opiz. Vahl’s species, one of doubtful status, 
seems to be an American form, Haenke’s Luzon specimen being either 
erroneously localized or wrongly identified. 
PIPER LATUM HBK.; Opiz in Presl Rel. Haenk. 1 (1828) 159. 
“Hab. ad portum Sorzogon in insula Luzon” Opiz. The record was 
unquestionably based on an American specimen erroneously localized in 
the Haenke Malaspina Expedition collections. 
PIPER RADICANS Vahl Enum. 1 (1804) 333; Opiz in Pres] Rel. Haenk. 1 
(1828) 159; C. DC. Prodr. 16* (1869) 379; F.-Vill. Novis. App. 
(1880) 176. 
Vahl’s type was from the Isle of France; Opiz was doubtless in error 
in referring Haenke’s Luzon specimen to this species. 
PIPER SYLVESTRE Lam. Ill. 1 (1791) 79; Vahl Enum. 1 (1804) 326; C. DC. 
Prodr. 16* (1869) 361; F.-Vill. Novis. App. (1880) 175. 
Lamarck’s type material was from “Insula Franciae, Malabaria, Philip- 
pinens.” As currently interpreted this is an Indian species.
