Illustrative specimen from Antipolo, Rizal Province, Luzon, 
January, 1914 (Merrill: Species Blancoanae No, 619). 
PTEROLOBIUM R. Brown 
Mimosa membranulacea Blanco FI. Filip. (1837) 739 (sp. nov.) =Reichardia 
pentapetala Blanco op. cit. ed. 2 (1845) 233 (nom. nov.); ed. 3, 2 
(1878) 71=PTEROLOBIUM MEMBRANULACEUM (Blanco) Merr. 
The species was reduced by Fernandez-Villar to the Indian 
Pterolobium indicum A. Rich., but is apparently specifically dis- 
tinct. It is to be noted that Blanco describes the flowers as 
having five stamens which is not true of Pterolobiwm; there is, 
however, no doubt but that Blanco’s statement was due to an 
error in observation, and equally no doubt but that his species 
is a Pterolobium and the form as here interpreted.

CAESALPINIA Linnaeus 
Poinciana pulcherrima Linn.; Blanco Fl. Filip. (1837) 333; ed. 2 (1845) 
232: ed. 3, 2 (1878) 69, t. 112=CAESALPINIA PULCHERRIMA 
(Linn.) Sw. 
This species, originating in tropical America, was introduced 
into the Philippines at an early date by the Spaniards and is 
now common and widely distributed in the Archipelago, where 
it is cultivated for ornamental purposes; it is also naturalized. 
It is universally known in the Philippines as caballero, i. e., 
gentleman. The name originally was espuela de caballero, es- 
puela meaning a spur, the name either transferred from the 
Spanish common name of larkspur, or derived from the spiny 
character of Caesalpinia pulcherrima. 
Illustrative specimen from Pasay, Rizal Province, Luzon, Sep- 
tember, 1914 (Merrill: Species Blancoanae No. 27). 
fe SAPPAN Linn.; Blanco Fl. Filip. (1837) 335; ed. 2 (1845) 
234; ed. 3, 2 (1878) 72, i 121. 
The Linnean species was correctly interpreted by Blanco. eS 
is widely distributed in the settled areas of the Philippines 
at low altitudes and is certainly a purposely introduced species 
in the Archipelago. Its common names are sappan and sibucao.
