60 SPECIES BLANCOANAE 
IMPERATA Cyrilli 
Saccharum koenigii Retz.; Blanco Fl. Filip. (1837) 44; ed. 2 (1845) 30; ed. 
3, 1 (1877) 56=IMPERATA CYLINDRICA Beauv. var. KOENIGII 
Benth. 
In my previous paper on Blanco’s species I erroneously con- 
sidered Blanco’s description of Saccharum koenigii to apply to 
Saccharum spontaneum Linn. It occurs throughout the settled 
areas of the Philippines, where the forests have been destroyed, 
practically occupying exclusively immense areas which are 
locally known as cogonales, from the almost universal Filipino 
name of the grass, cogon. Blanco’s description in part, “de la 
altura de un hombre,” applies to Imperata exaltata Brongn. 
Illustrative specimen from Taytay, Palawan, May, 1913 (Mer- 
rul: Species Blancoanae No. 381). 
SACCHARUM Linnaeus 
SACCHARUM OFFICINARUM Linn.; Blanco FI. Filip. (1887) 42; ed. 2 
(1845) 29; ed. 3, 1 (1877) 55, t. 18. 
The Linnean species was correctly interpreted by Blanco. 
Sugar cane is very extensively cultivated in the Philippines, 
is not a native of the Archipelago, but was unquestionably in- 
troduced into the Islands by the early Malayan invaders in the 
prehistoric period. 
Illustrative specimen from San Antonio, Laguna Province, 
Luzon, October, 1915, from cultivated plants; local name tub6é 
(Merrill: Species Blancoanae No. 959). 
Anthistiria gigantea Blanco Fl. Filip. (1837) 49; ed. 2 (1845) 33; ed. 3, 
1 (1877) 62, non Cav.=SACCHARUM SPONTANEUM Linn. subsp. 
INDICUM Hack. 
Fernandez-Villar considered that Blanco correctly iieersretcd 
Cavanilles’s species, in which opinion I concurred in my previous — 
consideration of Blanco’s species. His description, however, 
applies unmistakably to Saccharum spontaneum, which is very 
common and widely distributed in the Philippines and is 
universally known in the Tagalog provinces as taldhib, the local 
name cited by Blanco. :
