Willdenow gives Malabar as its native country, but on the paper of 
Klein, in Willdenow’s herbary, is written “ Frankenb. 1799," which 
signifies doubtless Tranquebar on the coast of Coromandel. In Sir W. 
Hooker's herbarium are specimens from Madras (Dr. Wight, No. 131). 
In the herbaria of Desfontaines, Agardh, and others, I have seen 
specimens distributed by Hornemann under the name of Ch. furcata, 
Roxb., without indication of the locality. 
A very remarkable species, peculiar to the East Indies, in size resem- 
bling Nitella translucens, somewhat thinner than the nearest related 
Ch. australis. It is without annular incrustation, as is seen some- 
times in Nitella syncarpa. The name refers to the coral-red colour 
however, have a black nut without calcareous covering, and are con- 
sigecaBiy larger than in the following species.
