§4 SPECIES BLANCOANAE 
1767, from the Island of Cebu. Graebner, Engl. Pflanzenreich ~ 
2 (1900) 10, does not credit Typha orientalis Presl to the Philip- | 
pines, giving its distribution as northern China and Japan, and — 
reducing it to T. shuttleworthit Koch & Sond. as a subspecies. 
It is widely distributed in the Philippines at low altitudes, being 
generally known to the Tagalogs as balangot and to the Visayans — 
as lampacanai. ; 
Illustrative specimen from Los Bafios, Laguna Province, Luzon, — 
June, 1914, comm. E. Quisumbing (Merrill: Species Blacoanae — 
No. 38). 
PANDANACEAE 
FREYCINETIA Gaudichaud 
Tillandsia pseudo-ananas Blanco Fl. Filip. (1837) 853 (sp. nov.); ed. 2 
(1845) 162; ed. 3, 1 (1877) 292=FREYCINETIA sp. . 
Naves reduced this to F'reycinetia insignis Blume, a species — 
that does not extend to the Philippines. The description of the | 
habit and leaves applies better to Pandanus, than to Freycinetia, — 
but the seed characters, taken from very young fruits, indicate — 
Freycinetia; it is very probable that Blanco never saw the living 
plant, but based his description on material brought to him. 
The species may even have been based on a mixture of material 
from two different plants. At any rate, the characters are 
so very imperfectly expressed that it is impossible more than to — 
indicate its probable generic reduction. 
PANDANUS Linnaeus f. 
PANDANUS RADICANS Blanco FI. Filip. (1837) 780 (sp. nov.); ed. 20 
(1845) 537; ed. 3, 3 (1879) 184. 
This is a valid species, and was erroneously reduced by Naves | 
to Pandanus bagea Mig. Blanco’s specimens were from Leyte, — 
where it is known as olango. It has been rediscovered there 
by Mr. Elmer, the plant still being known as olango; see Elmer 
Leafl. Philip. Bot. 1 (1906) 74. The nomen nudum, Pandanus 
olango Blanco ex Espejo & Garcia Suppl. Cat. Sem. Hort: Bot. 
Manil. 1869 (1871) 6, (1876) 14, from its name, is the same. 
PANDANUS EXALTATUS Blanco Fl. Filip. (1837) 778 (sp. nov.); ed. 2 
(1845) 586; ed. 8, 3 (1879) 183. 
This species was erroneously reduced by Naves to Pandanus 
fascicularis Lam., a species that does not extend to the Philip- 
pines, and one to which Blanco’s description does not remotely 
apply. Two species are included by Blanco, if not in the descrip- 
tion, then in the discussion following: “Es comin en las playas
