LOCHNERA Reichenbach 
Vinca rosea Linn.; Blanco Fl. Filip. (1837) 116; ed. 2 (1845) 84; ed. 3, 
1 (1877) 154, t. 42=LOCHNERA ROSEA (Linn.) Reichb. (Ammocallis 
rosea Small). 
This species was undoubtedly introduced from tropical Amer- 
ica; it is now widely distributed in the Philippines at low 
altitudes and is frequently thoroughly naturalized.

TABERNAEMONTANA Linnaeus 
Tabernaemontana laurifolia Blanco Fl. Filip. (1837) 114; ed. 2 (1845) 82; 
ed. 3, 1 (1877) 150, t. 41, non Linn. =TABERNAEMONTANA PANDA- 
CAQUI Poir. : 
This species is very common at low altitudes in Luzon and 
is especially abundant in and about Manila. It is universally 
known as pandacaqui. Sonnerat’s figure, on which Poiret’s spe- 
cies was based, was drawn from a Philippine specimen, not from 
a New Guinea plant as indicated in de Candolle’s Prodromus.

7 TABERNAEMONTANA POLYGAMA Blanco FI. Filip. ed. 2 (1845) 82 
(poligama) (sp. nov.); ed. 38, 1 (1877) 151. 
There is no doubt that the species described as Tabernae- 
montana puberula Merr. in Philip. Journ. Sci. 4 (1909) Bot. 319 
is identical with Tabernaemontana polygama Blanco. The spe- 
cies is common in thickets in the vicinity of Manila. The corolla 
falls very soon after the flowers open, and Blanco apparently 
interpreted the flowers with fallen corollas as female flowers.

This species is widely distributed in the Philippines; it is 
abundant in the provinces contiguous to Manila and is generally 
known as bayag usa.
