Cordia kanehirai Hay. Icon. PI. Formos. 
6: 31, 1916; Hou in Taiwania 1; 207, 
1950. Syn. nov. 
Luzon; Formosa, in the thickets in southern 
part only, scarce. 
Formosa: Koshun, E. Matuda 1333 (NTU); 
Kuraru, Koshun, R. Kanehlra 7 (isotype of 
C kanehirai, photo US). 
Hayata originally placed this plant as a 
close ally of C. cumingiana. In comparing spe- 
cimens from the two regions, it is found that 
the Formosan plant cannot be differentiated 
from the Luzon plant and must be considered 
as conspecific. 
2. Cynoglossum lanceolatum Forsk, FI. 
Aegypt. Arab. 41, 1775; Hou in Taiwania

Cynoglossum alpestre Ohwi in Acta Phytotax. 
Geobot. 2: 150, 1933; Hou in Taiwania 
1: 218, 1950. Syn nov. 
India, Southern China to the Philippines; 
Formosa, mountain regions. 
Formosa: No precise locality, A. Henry 
1013 (US); Arisan, T. Tanaka 320 (US); S. 
Suzuki, ]\Ay 17, 1937 (NTU). 
No isotypes of Ohwi’s species are available, 
but, among the cited specimens, Suzuki j. n. 
most closely approaches the original descrip- 
tion of C. alpestre in having longer, denser 
hairs and smaller, thicker leaves than other 
specimens of C. lanceolatum. These characters 
are, however, evidently due to higher eleva- 
tions, whereas there are no structural differ- 
ences between plants of higher and lower 
altitudes. Cynoglossum alpestre Ohwi can at most 
be considered an alpine form of the species 
C. lanceolatum, but, in view of the wide dis- 
tribution and variable nature of the species, 
it seems not desirable to recognize it taxo- 
nomically. 
3. Ehretia navesii Vidal, Rev. PL Vase. Filip. 
194, 1886. 
Ehretia resinosa Hance in Jour. Bot. 299, 
1880; Hou in Taiwania 1: 203, 1950. 
Syn. nov. 
Ehretia formosana Hemsl. in Jour. Linn. 
Soc. Bot. 26: 144, 1896. Syn. nov. 
Philippine Islands; Formosa, in southern 
part, along the seashore. 
Formosa: Takao, A. Henry j. n. (US), K. 
Moritani 2308 (NTU); Kuraru, E. H. Wilson 
10967 (US). 
The Formosan plant proves to be the same 
as the Philippine E. navesii Vidal, a charac- 
teristic plant readily distinguished by the 
long-linear and persistent calyx-lobes which 
enclose the globose fruit at maturity.

This is an exceedingly common species in 
the Philippine Islands, generally known as 
"P. integri folia." This species was confused by 
many authors, including Kanehira, with P. 
odorata, another Philippine species that occurs 
also in southern Formosa. In P. odorata the 
leaves are densely tomentose beneath. In P. 
nauseosa the leaves are more or less glabrous 
beneath.

forests near seashore in northern and southern 
parts.
