Dane's Island, near Whampoa, September 10, 1751. Torenia bentha- 
miana Hance, which is certainly a synonym of T. glabra Osbeck, is 
reported by Dunn &Tutcher^^ from Hongkong, Swatow, and Whampoa. 
Trapa bicornis Osbeck, Dagbok Ostind. Resa 191 . 1757. 
This appears as a footnote under the Chinese name ling-kamm or 
leng'ka, as Trapa bicornis vid. Plum. Icon. T. 67," with a statement 
in Swedish to the effect that the fruit looks like two horns joined to- 
gether, with a kernel in the middle, that it is sold in the shops, and that 
it is eaten by poor people. Osbeck's name antedates that of the 
younger Linnaeus who is generally cited as the authority for the 
species.^^ Trapa bicornis is, by many authors, considered only a form 
of Trapa natans L. 
Urena chinensis Osbeck, Dagbok Ostind. Resa 225. 1757 = ? Urena 
lobata L. 
This is listed in Index Kewensis as follows : " Urena chinensis Osbeck, 
Voy. ed. Angl. i, 363 (Quid?)," the English edition of Osbeck's work 
having been published in the year 1771 . The description is inadequate, 
but the plant is probably merely a form of Urena lobata L. The 
original description is as follows: " Urena {chinensis) caule erecto, 
floribus majoribus," followed by a statement in Swedish to the effect 
that it grew on the lower slopes of hills not far from the shore. It was 
observed near Whampoa, September 22, 1751.
