festly the same species. It is common and widely distributed 
in the Philippines at low altitudes and is widely known as alagao. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
January, 1914 (Merrill: Species Blancoanae No. 435). 
Premna cordata Blanco FI. Filip. (1837) 489, non R. Br.=Premna tomen-

PREMNA CUMINGIANA Schauer. 
Blanco’s description is entirely inadequate, but Premna cum- 
ingiana Schauer, which is not uncommon in the provinces con- 
tiguous to Manila, is undoubtedly the species intended by him. 
It is the whole basis of Premna cardiophylla Schauer, and 
Schauer’s species, which was published merely as a new name 
for Premna cordata Blanco (non R. Br.), thus becomes a 
synonym of Premna cumingiana Schauer. 
Illustrative specimens from Angat, Bulacan Province, Luzon, 
December, 1914 (Merrill: Species Blancoanae No. 681); Rizal 
Province, Luzon, June, 1916 (Merrill: Species Blancoanae No.

VITEX Linnaeus 
VITEX TRIFOLIA Linn.; Blanco FI. Filip. (1837) B18; ed. 2 (1845) 358; 
ed. 3, 2 (1878) 297, t. 226 (poor). 
Blanco correctly interpreted the Linnean species which is 
common along the seashore throughout the Philippines. It is 
commonly known as lagundt, 
Illustrative specimen from Taytay, Palawan, May, 1913 
(Merrill: Species Blancoanae No. 302). 
Vitex repens Blanco Fi. Filip. (1837) 513 (sp. nov.); ed. 2 (1845) 358; 
ed. 3, 2 (1878) 297=VITEX TRIFOLIA Linn. var. OVATA (Thunb.) 
(V. ovata Thunb., V. trifolia Linn. var. unifoliolata Schauer). 
This species is not uncommon on sandy beaches along the 
seashore, and is widely distributed in the Philippines. Although 
very distinct in habit, and in its leaves usually reduced to a single 
leaflet, I doubt very much if it is specifically distinct from the 
erect Vitex trifolia Linn. 
Illustrative specimen from Bauang, Batangas Province, Luzon, 
February, 1915, there known as lagunding dagat from lagundi a 
(Vitex trifolia) and dagat (ocean) (Merrill: Species Blancoanae 
No. 814). 
Vitex leucoxylon Blanco Fl. Filip. (1837) 516 (leucoxilon); ed. 2 (1845) 
359; ed. 3, 2 (1878) 300, ¢. 228, non Linn. =VITEX NEGUNDO Linn. 
Vitex negundo Linn. is common and widely distributed in the 
Philippines at low and medium altitudes, probably introduced. 
_ Blanco’s Vitex leucoxylon is, in part only, referable here. His — -
