Philippines at low and medium altitudes; certainly introduced 
but of prehistoric introduction.

CLITORIA Linnaeus 
CLITORIA TERNATEA Linn.; Blanco Fl. Filip. (1837) 590; ed. 2 (1845) 
412; ed. 8, 2 (1879) 391, t. 301. 
The Linnean species was correctly interpreted by Blanco. It 
is very common and widely distributed in the settled areas at 
low and medium altitudes and is certainly an introduced plant 
in the Archipelago.

ERYTHRINA Linnaeus 
Erythrina carnea Blanco Fl. Filip. (1837) 564; ed. 2 (1845) 393; ed. 
3, 2 (1879) 359, t. 217, non Dryand.=ERYTHRINA VARIEGATA Linn. 
var. ORIENTALIS (Linn.) Merr. Interpret. Herb. Amb. (1917) 276 
(£, indica Lam.). 
This species is very common and widely distributed in the 
Philippines, especially along the seashore and is universally 
known as dap-dap. It is well to note that Erythrina indica 
Lam. (1788) does not differ specifically from Erythrina varie- 
gata Linn. (1754), the type of Hrythrina variegata Linn. being 
only a form of EH. indica Lam. with variegated leaves.

Erythrina picta Blanco Fl. Filip. (1837) 565, non Linn.=Erythrina caffra

This species is widely distributed at low altitudes in the Phil- 
_ippines, in low wet lands, in swampy places, etc.

MUCUNA Adanson 
Negretia urens Blanco Fl. Filip. (1837) 586; ed. 2 (1845) 409; ed. 3, 2 
(1879) 387, non Tussac=MUCUNA NIGRICANS (Lour.) Steud. 
This was reduced by Fernandez-Villar to Mucuna monosperma 
DC., which is certainly an error as Blanco’s description does 
not apply to de Candolle’s species, which, moreover, does not 
extend to the Philippines. In my previous consideration of 
Blanco’s species, I reduced it to Mucuna imbricata DC., but
