y Petaloma coccinea Blanco Fl. Filip. (1887) 345 (sp. nov.); ed. 2 (1845) 
| 240; ed. 3, 2 (1878) 883=LUMNITZERA LITTOREA (Jack) Voigt 
(L. coccinea W. & A., L. purpurea Presl).

along the seashore. 
Illustrative specimen from Tayabas Province, Luzon, April,

ed. 8, 2 (1878) 82, t. 126=LUMNITZERA RACEMOSA Willd. 
The species as it occurs about Manila Bay is a small shrub 
rarely over 3 meters high, frequently less than 1 meter high. It 
is known to the Tagalogs as cwlasi.

MYRTACEAE 
PSIDIUM Linnaeus 
Psidium aromaticum Blanco Fl. Filip. (1837) 417, non Aubl.=Psidium 
pyriferum Linn.; Blanco op. cit. ed. 2 (1845) 292; ed. 3, 2 (1878) 
178, t. 48—=PSIDIUM GUAJAVA Linn. 
The guava was introduced from Mexico at an early date by 
the Spaniards. It is now very abundant and widely distributed 
in the settled areas of the Archipelago and is thoroughly na- 
turalized. It is commonly known as bayabas. The fossil leaves 
from volcanic tuff formations at Guadalupe, Mandaloyon, etc., 
referred by Blanco to this species, were certainly wrongly 
identified by him. 
Illustrative specimen from Umingan, Pangasinan Province, 
Luzon, May, 1914 (Merrill: Species Blancoanae No. 11). 
DECASPERMUM Forster 
Legnotis lanceolata Blanco FI. Filip. (1837) 445 (sp. nov.) =Metrosideros 
pictipetala Blanco op. cit. ed. 2 (1845) 295 (nom. nov.); ed. 3, 2 
(1878) 183—DECASPERMUM FRUTICOSUM Forst. (D. panicula- 
tum Kurz). 
Fernandez-Villar reduced Metrosideros pictipetala Blanco to 
Metrosideros vera Rumph., which can hardly be correct. As 
pointed out by C. B. Robinson, Philip. Journ. Sci. 4 (1909) Bot. 
337, the identification of Blanco’s species with Decaspermum 
paniculatum is fairly probable. The name Legnotis lanceolata
