Note 367 — Chapter XXIX
Reading edition
In some tanks we found Hydropeltis, an American and Australian plant allied to Nymphæa. Mr. Griffith first detected it here, and afterwards in Bhotan, these being the only known habitats for it in the Old World. It grows with Typha, Acorus Calamus (sweet flag), Vallisneria, Potamogeton, Sparganium, and other European water-plants.
