NYCTAGINACEAE 
MIRABILIS Linnaeus 
Mirabilis longiflora Blanco FI. Filip. (1837) 77; ed. 2 (1845) 57; ed. 3, 1 
(1877) 109, non Linn. =MIRABILIS JALAPA Linn. 
This species is common and widely distributed in cultivation, 
often also found in waste places, throughout the Philippines. It 
was introduced from Mexico at an early date and is more gener- 
ally known under the Spanish names maravilla and a las cuatro. 
Illustrative specimen from Batangas Province, Luzon, August, 
1914 (Merrill: Species Blancoanae No. 84). 
BOERHAAVIA Linnaeus 
BOERHAAVIA DIFFUSA Linn.; Blanco Fl. Filip. (1837) 8; ed. 2 (1845) 
6; ed. 3, 1. (1877) 11, t.98, 
~The Linnean species was correctly interpreted by Blanco. 
There is no doubt that B. repens Linn. is an exact synonym. It 
is common and widely -distributed in the Philippines in the 
settled areas at low altitudes; certainly an accidentally in- 
troduced weed. 
Illustrative specimen from Manila, Luzon, December, 1913 
(Merrill: Species Blancoanae No. 274). 
PISONIA Plumier 
PISONIA ACULEATA Linn.; Blanco Fl. Filip. (1837) 195; ed. 2 (1845) 
, 187; ed. 3, 1. (1877) 247, t. 394. 
The Linnean species was correctly interpreted by Blanco. 
The species is of wide distribution in the Philippines at low 
altitudes, _ 
Illustrative specimen from Antpols, Rizal Province, Egor 
January, 1914 (Merrill: Species Blancoanae No. 759). 
Buginvillea racemosa Blanco FI. Filip. (1887) 307 (sp. nov.) ; ed. 2 (1845) 
214; ed. 3, 2 (1878) 36 (Bugainvilla) =PISONIA EXCELSA Blume. 
Cedrota guianensis Blanco Fl. Filip. ed. 2 (1845) 213; ed. 3, 2 (1878) 33, 
non Raeusch.—PISONIA EXCELSA Blume. : 
Fernandez-Villar reduced Buginvillea racemosa Blanco to 
Pisonia excelsa Blume and Cedrota guianensis to P. umbelli- 
fera Seem.; but, judging from our large series of specimens of 
Pisonia from all parts of the Philippines, I am now of the 
opinion that but a single species is represented by Blanco’s two 
descriptions, and that both species are probably Pisonia excelsa 
Blume. Specimens recently received from Cebu under the Visa- 
yan name tac-an, cited by Blanco under his Cedrota guianensis,
