This species is widely distributed in the Indo-Malayan region. 
Sisymbrium sinapis Burm. f. was based on Javan material, while 
that on which S. indicum Burm. f. was based was from India. 
Doubtless the material Linnaeus had in describing the species 
one year earlier was a part of the same collection. 
NASTURTIUM HETEROPHYLLUM Blume Bijdr, (1825) 50. 
* ? Cardamine indica Burm. f. Fl. Ind. (1768) 140. “Habitat in Java.” 
De Candolle, who saw Burman’s specimen in the Delessert 
herbarium, retained this in Cardamine, with the comment “An 
potius inter Nasturtia ad sectionem Clandestinariae referenda?” 
while Schulz, Monogr. Gattung Cardamine in Engl. Bot. Jahrb. 
32 (1903) 594, states that it is a Nasturtium. I suspect that 
it is the same as Nasturtium heterophyllum Blume. Burman’s 
specific name, however, is invalidated in Nasturtium by N. indi- 
cum (Linn.) DC. 
FARSETIA Turra 
FARSETIA CANESCENS (Willd.) comb. nov. 
Heliophila canescens Willd. Sp. Pl. 3 (1800) 528. 
Arabis heliophila DC. Syst. 2 (1821) 287, Prodr. 1 (1824) 147. 
Heliophila incana Burm. f. Fl. Ind. (1768) 140, t. 46, f. 2, non Farsetia 
incana R. Br. “Habitat in India.” 
Farsetia jacquemontii Hook. f. & Th. Fl. Ind. 1 (1855) 140. 
De Candolle’s and Willdenow’s binomials are based on Bur- 
man’s description; the latter’s specific name being invalidated 
in Farsetia, I propose to adopt Willdenow’s specific name. Far- 
setia jacquemontii Hook. f. & Th. is clearly a synonym. 
LEGUMINOSAE 
PROSOPIS Linnaeus 
PROSOPIS SPICIGERA Linn. Mant. 1 (1767). 68. 
Prosopis spicata Burm. f. Fl. Ind. (1768) 102. “Habitat Coromandeli.” 
This was described one year earlier by Linnaeus and is a well- 
known Indian species. Both descriptions were doubtless based 
on material from the same collection. 
ACACIA Willdenow 
ACACIA TRUNCATA (Burm. f.) Hort. ex Hoffmsg. Pfl. Verz. (1824) 34. 
Adianthum truncatum Burm. f. Fl. Ind. (1768) 285, t. 66, f. 4 
“Habitat in India.” 
Acacia decipiens R. Br. in Ait. Hort. Kew. ed. 2, 5 (1813) 463.
