19, 3 Merrill: Burman’s Flora Indica 355 
species is South African; it would seem, therefore, that Burman 
was in error in accrediting his species to Persia. 
ONONIS Linnaeus 
ONONIS PERSICA Burm. f. FI. Ind. (1768) 157, t. 49, f. 1. “Habitat 
in Persia.” 
This is supposed to be a synonym of Ononis sicula Guss.; 
this being so, Burman’s specific name is much the older and 
should be retained. 
LOTUS Tournefort 
LOTUS GARCINI DC. Prodr. 2 (1825) 212. 
Aspalathus persica Burm. f. FI]. Ind. (1768) 155. “Habitat in’ Persia 
& Malabaria.” 
The Persian specimen, the type of the species, is a Lotus, 
and Burman’s name is the basis of Lotus garcini DC. The 
reference to Rheede Hort. Malabar. 9: 71, t. 38, must be ex- 
cluded, as it does not represent the species Burman actually 
described. The type is in the Delessert herbarium. The 
specific name persica is invalidated in Lotus by Lotus persicus 
Burm. f. 
INDIGOFERA Linnaeus 
INDIGOFERA COLUTEA (Burm. f.) comb. nov. 
Galega colutea Burm, f. Fl. Ind. (1768) 172. “Habitat in India.” 
Tephrosia colutea Pers. Syn. 2 (1807) 326. 
Indigofera viscosa Lam. Encycl. 3 (1789) 247. 
This species is currently known as Indigofera viscosa Lam., 
but Burman’s specific name is older and should be retained. 
INDIGOFERA ARGENTEA Burm. f. Fl. Ind. (1768) 171. “Habitat in 
Persia.” 
Burman’s name antedates Indigofera argentea Linn. Mant. 
2 (1771) 273 and should be maintained, with Indigofera semi- 
trijuga Forsk. as a synonym. The proper name for the species 
described by Linnaeus as Indigofera argentea is I. articulata 
Gouan., for his species does not seem to have been based on 
specimens of the same collection as Burman’s. 
INDIGOFERA ENNEAPHYLLA Linn. Mant. 2 (1771) 272. 
Hedysarum prostratum Linn. Mant. 1 (1767) 102, non Indigofera 
prostrata Perr. 
Hedysarum prostratum Burm. f. FI. Ind. (1768) 168, ¢. 55, f.>1. 
“Coromandeli.” 
Hedysarum prostratum of Linnaeus and of Burman were 
doubtless based on material of similar origin. It is a synonym 
of Indigofera enneaphylla Linn.
