common lemon. As noted by Swingle the specific name does not 
appear in the original (1757) Swedish edition of Osbeck's work, but 
does in the German (1765) edition. The original description, in Latin, 
appears as a footnote from the Chinese name Lam-tjes on page 192 or 
Osbeck's Dagbok, and is as follows: "Caulis teres, subscaber, cinereus, 
pallide striatus. Rami inordinati, patentes, reflexi, rarius spinosi. 
Ramuli spinis rectis, acutissimis, alternis vel ex alis ramulorum. Folia, 
alterna, oblongo-lanceolata, petiolata, subcrenata. Petioli subalati,, 
lineares." There is a discussion in Swedish to the effect that the 
Chinese make punch from the unripe fruits that they sell to the 
sailors, and that the plants are grown in pots for sale.

Reise Ostind. China 250. 1765. 
Swingle^^ has adopted Osbeck's name for the sweet orange which 
he considers to be specifically distinct from the sour orange (Citrus, 
aurantium L.). There is no description in the original Swedish editioni 
of Osbeck's work, and in the German edition (1765) is given a very 
inadequate description which includes also the mandarin orangej 
(Citrus nobilis Lour.). 
Clematis chinensis Osbeck, Dagbok Ostind. Resa 205, 242. 1757. 
Osbeck's species should not be confused with Clematis chinensis 
Retz., which is apparently an entirely different form. It is probable 
that Clematis meyeniana Walp. is a synonym of Clematis chinensis^ 
Osbeck. The original description, on page 205, is as follows: ''Cle- 
matis chinensis. Obs. Plurima habet cum Clematide Vitalba, at folia 
lanceolata, angustissima, & flores minores," while on page 242, the 
following additional data are given : "Obs, pistilla 3 ad 6, stylis plumosis 
in orbem positis, reflexis. Stam. O obseruavi. Frutex scandens, 
ramosissimus." In Index Kewensis the species is included, but the 
place of publication is given as the 1771 English edition "Clematis 
chinensis Osbeck Iter. ed. Angl. i, 392"; here it is erroneously reduced 
to the European Clematis recta L. Osbeck observed the species in the 
neighborhood of Canton September 8, and again near Whampoa, 
October 20, 1751. Nine species of the genus are known from Kwang- 
tung Province, but considering the characters given by Osbeck, and 
the distribution of the various species, the probabilities are very great 
that Clematis meyeniana Walp. is the species intended by Osbeck.
