of the Monandrous Plants of India. NE 99 
-Of Amomum there appear to be in the garden at Calcutta only 
four species; two of which, the Cardamomum and Angustifolium, 
are already distinctly known. The Aculeatum and Maximum of 
Roxburgh appear, from their echinated capsules, to resemble the 
Globba crispa, viridis, and rubra of Rumph. Amb. vi. 60, 61; but | 
Dr. Roxburgh conceives them to be different plants. 
Of the genus Zingiber Dr. Roxburgh has given nine species, 
only four of which have before been described. Of the remainder, 
there are two, the capitatum and marginatum, which are said to 
flower from a terminal spike ; a mode of inflorescence so entirely 
different from that of the rest of the genus, which is an imbricated 
radical scape, as to induce a doubt whether they may not be 
found, on further investigation, to belong to some other genus. 
Amongst the additions made by Dr. Roxburgh to Zingiber, I 
have not included the Z. Cassumunar, although he has affixed to 
it the letter R. in the same manner as to the other newly de- 
scribed plants; this being already known in Europe, and de- © 
scribed in my Paper on Scitaminee in the Linn. Trans. under the 
name of 2. purpureum. It flowered in the Liverpool Botanic 
Garden in the year 1810; and the drawing then made of it per- 
fectly agrees with the excellent figure given by Dr. Roxburgh. 
At that time I was not.aware that this plant was the Cassumunar 
of the shops, which has now been ascertained by Sir Joseph 
Banks and Dr. Coombe. The specific name of purpureum 
should therefore be withdrawn, and the more determinate one of 
Cassumunar retained. The figure given in Andrews's Bot. Repo- 
sitory, pl. 555, under the name of Z. Cliffordia, is the same plant, 
which has also been since figured in the Bot. Mag. No. 1426, 
under its proper name, on the authority of Dr. Roxburgh.  . 
Of Costus, Dr. Roxburgh has described only one species, the 
Speciosus ; and even this is not so clearly defined as to be free
