176 SPECIES BLANCOANAE 
Guilandina bonducella Linn. is manifestly identical with Caesal- 
pinia crista Linn., the latter name being the older; see Urban 
Symb. Antill. 2 (1900) 269-271; Merr. in Philip. Journ. Sci. 5 
(1910) Bot. 53. The species is found throughout the Philip- 
pines along the seashore, its most generally used native name 
(Tagalog) being calambibit. 
Illustrative specimen from Pasay, Rizal Province, Luzon, 
October, 1914 (Merrill: Species Blancoanae No. 398). 
Guilandina nuga Linn.; Blanco FI. Filip. (1837) 344; ed. 2 (1845) 240; 
ed. 3, 2 (1878) 81, t. 150=CAESALPINIA NUGA (Linn.) Ait. 
This species is found along tidal streams, muddy shores, etc., 
throughout the Philippines, within the influence of salt or brack- 
ish water. It is to be noted that the specimen in Hermann’s 
herbarium cited by Linnaeus under C. crista, is C. nuga and not 
C. erista as the latter is usually interpreted; see Trimen FI. 
Ceyl. 2: 99. 
Iliustrative specimen from Manila, Luzon, December, 1914 
(Merrill: Species Blancoanae No. 649). 
MEZONEURUM Desfontaines 
Caesalpinia torquata Blanco FI. Filip. (1837) 336 (sp. nov.) =Mezoneurum 
procumbens Blanco op. cit. ed. 2 (1845) 235 (nom. nov.); ed 3, 2 
(1878) 73=MEZONEURUM LATISILIQUUM (Cay. 1799) Merr. in 
Philip. Journ. Sci. 5 (1910) Bot. 57 (Mezoneurwm glabrum Desf.). 
Blenco’s species was correctly reduced by Fernandez-Villar 
to Desfontaine’s species, but Bauhinia ? latisiliqua Cav. supplies 
an older specific name. Cavanilles’s species was a mixture, as 
he figured and described the leaves of Bauhinia and the fruits 
of the present species; the specific name having been taken 
from the fruits, I have interpreted the species as Mezoneurum, 
rather than as a Bauhinia. 
Illustrative specimen from Antipolo, Rizal Province, Luzon, 
March, 1915 (Merrill: Species Blancoanae No. 875). 
Caesaipinia ignota Blanco Fl. Filip. (1837) 336 (sp. nov.); ed. 2 (1845) 
235; ed. 3, 2 (1878) 722=MEZONEURUM PUBESCENS Desf. . 
The species is common on the dry grass-covered hills about 
Manila and is of local occurrence in Luzon in those regions where 
there is a protracted dry season. Philippine material has been 
compared with Desfontaine’s type in the Paris Museum by 
Lecomte; see Philip. Journ. Sci. 5 (1910) Bot. 56. 
lijustrative specimen from Angat, Bulacan Province, Luzon, 
September, 1913 (Merrill: Species Blancoanae No. 294).
