110 SPECIES BLANCOANAE : 
that the leaves lack the dark-colored median spot, and that the 
rhizomes yield a yellow dye. I consider it very probable that 
it too is but a synonym of Curcuma zedoaria Rosc. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
June, 1915, here known as tamo and as barac, the former cited 
by Blanco as one of the native names of Costus luteus, the latter 
as one of the native names of C. nigricans (Merrill: Species 
Blancoanae No. 966). 
KAEMPFERIA Linnaeus 
Kaempferia rotunda Blanco Fl. Filip. (1837) 5; ed. 2 (1845) 4 (Kaemphe- 
ria); ed. 3, 1 (1877) 7, non Linn. =KAEMPFERIA GALANGA Linn. 
This species is widely distributed; it is of local occurrence in 
the settled areas of the Philippines at low and medium altitudes, 
but was certainly introduced into the Archipelago in prehistoric 
times; it is not a native of the islands. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
August, 1915, here known as duso or dusol (Merrill: Species 
Blancoanae No. 942). 
KOLOWRATIA Presl 
Renealmia gracilis Blanco Fl. Filip. (1837) 1 (sp. nov.) =Renealmia exal- 
tata Blanco op. cit. ed. 2 (1845) 1; ed. 3, 1 (1877) 2, t. 1, non Linn. 
f.=KOLOWRATIA ELEGANS Presl (Alpinia gracilis Rolfe, Alpinia 
elegans K. Sch.). 
This species is common and widely distributed in the Philip- 
pines at low and medium altitudes, and is exceedingly variable 
in leaf size. Its most common native names are talbac or tagbac. 
It was erroneously reduced by Naves to Alpinia gigantea Blume, 
a species that does not occur in the Philippines. Blanco’s de- 
scription typifies Hellenia gracilis Hassk. in Flora 47 (1864) 19. 
Illustrative specimen from Umingan, Pangasinan Province, 
Luzon, May, 1914 (Merrill: Species Blancoanae No. 404). 
ZINGIBER Adanson — 
Amomum zingiber Linn.; Blanco Fl. Filip. (1837) 2; ed. 2 (1845) 2; ed. | 
3, 1 (1877) 3, t. 131=ZINGIBER OFFICINALE Rosc. ; 
Blanco correctly interpreted the Linnean species, the form © 
being the ordinary ginger which is cultivated in and about the 
larger towns of the Philippines to supply the local demand. 
Blanco’s description typifies Zingiber blancoi Hassk. in Flora 
47 (1864) 20. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
October, 1916 (Merrill: Species Blancoanae No. 1024).
