and as to the awns, Sir Joseph Hooker and I myself have seen a 
very few perfectly and imperfectly awned spikelets in Griffith's 
Mergui specimen of 'lemon-grass.' Nees also insists on the 
striking citron odour of the leaves. In the absence of the 
originals, no absolute proof is possible that Nees's A)idmp„g t ,n 
citratus was the lemon-grass; but so far as circumstantial 
evidence is admissible, it appears quite reasonable to assume 
their identity until proof to the contrary is forthcoming, and 
consequently to adopt his name. If the occurrence of awns was 
actually general in the Breslau plant, it might have been a case of 
reversion to the ancestral form, which no .loubt was awned. In 
corroboration of my view of the identity of Nees's * Andropogon 
<-it rat, is,' 1 may add, that Nees's brother, Theodor Friedrich, has 
also given a description of ' Andropogon citratus'' in 'Geiger's 
Pharmaceutische Botanik,' 2nd ed., vol. i., p. 147. This description 
is shorter, but in some respects is more precise and is thus 
supplementary to that in the • Allgemeine Gartenzeitung ' ; he 
unhesitatingly identifies it with Fleming's ' lemon-grass.' Further, 
there is in the Turin herbarium a specimen of lemon-grass, 
collected by Bertero in Jamaica ami received in 1821 by Balbis, 
who himself named it Andropogon citratus. As Balbis had been 
growing ''Andropogon citratus, DC since 1812 or even before 
that date, his determination may certainly be accepted as another 
proof of the identity of 'lemon-grass' and 'Andropogon citratus: 
Steudel evidently did not know of De Candolle's and Nees's 
Andropogon citratus. Being, however, aware of the fact that 
Roxburgh's l A ndropogon Schoenanthus' is not that of Linnaeus, 
he tried to overcome the difficulty by dropping Linnaeus's 
name for the Arabian plant which he enumerates as 'Andropogon 
'■-iicin/iatus, Hochst.,'* retaining ' A/r>r»/r> : ;»f Sdinenanth'is' 
with Roxburgh as author, for the other, that is, the 'lemon-grass' ; 
but he forgot what he had done, and described the plant a 
second time, on p. 395, as 'Andropogon Roxburgh**, Neefl 
(MSS.),' this time quo! • Roxb -> as a 
synonym. . ; rghii, Nees, is the name used on 
the distribution labels of Wight's No. 1699, which is undoubtedly 
1 lemon-grass.' 
In 1883, Hackelt described specimens of a grass, termed ' Capim 
de Cheiro ' by the Brazilians, as Andropogon ceriferus ; four years 
later he reduced it as a variety to Andropogon Nardus,^ adding 
a number of West Indian specimens, among them Sintenis' 
'Limoncillo' from Porto Rico; but these Brazilian and West 
Indian specimens are no more than typical ' lemon-grass.' 
There are therefore the following names in the field for the 
lemon-grass:—]. A. Schoenanthus, Roxb. non L. (Ih20) : -.A. 
citratus, DC. (1813), emend. Nees (1835) ; 3. A. A' 
Nees ex Stand. (1855); 4. A. ceriferus, Hack. (Lv\3); and 
5. A. Nardus, var. ceriferus, Hack. (1887). For the reasons 
stated above, I propose to adhere to the specific name citratus, so 
that the grass when transferred to Cymbopogon will have to be 
called Cymbopogon citratus.
