276 Mr.Roscor’s Remarks on Dr. Roxburgh’s Description 
rately distinguished by Father Kamel, the leaves of which are 
smooth, with a large purple cloud on their upper surface. 3. A 
plant with smooth leaves, the petioles of which only are purple: 
and 4. The plant figured in the Paradisus, with leaves entirely 
green, pubescent underneath. Now the most striking distinction 
noticed by Dr. Roxburgh in the habit of his two species is, that 
in Zedoaria the leaves are sericeous underneath, and the whole 
plant is green; whilst, in his Zerumbet, there is constantly a fer- 
rugineous mark down the centre of the leaves... Hence it clearly 
follows, that the Zerumbet of Roxburgh is the Zedoaria, or No. 2 
of Salisbury; and that the Zedoaria of Roxburgh is the 4th of 
Salisbury, figured in the Paradisus under the name of Aromatica ; 
both of them being entirely green, and the leaves sericeous or 
pubescent beneath. Both these plants are in the Botanic Gar- 
den at Liverpool, and agree perfectly with the descriptions given 
of them. 
From this statement I presume to think that the specific sand 
lation of Zedoaria should have remained with the plant to which 
it has always been attached ; viz. that with the marked or clouded 
leaf, and which Dr. Roxburgh himself expressly states is the plant 
which produces the Zedoary of the shops in England ; whilst the 
specific name of Zerumbet, as applied to a species of Curcuma, 
should be abolished, and that of Aromatica, already given by Salis- 
bury, retained in its stead. This seems the more necessary, as the: 
Amomum Zerumbet of Linn. and Willd. is not a Curcuma, but a Zin- 
‘giber. The Curcuma Zedoaria figured in the Bot. Mag., No. 1546, 
the leaf of which appears to be accidentally variegated with white 
spots, is probably also the true Zedoary, and a different plant 
from that figured in the Paradisus. The synonym, however, i in. the 
Bot. Mag. should have been to the Zerumbet of ar... ‘and 
not to the Zedoarta. e
