sis, a considerable number of nomina nuda occur which in Osbeck's 
work are here enumerated merely to call attention to the fact that 
they are nomina nuda. None of them occur in Index Kewensis. 
The list is as ioWows: Ahies chinensis, p. 217; Ammi Mspanicum, p. 57; 
Buxoides aculeata, p. 242 ; Callajavanica, p. 277; Cacalia incana, p. 234; 
Cucurbita chinensis, p. 292; Curcuma chinensis, p. 205; Cyperus dicho- 
tomus, p. 229; Gratiola virginianoides, p. 205; Nyctanthes orientalis, 
p. 136; Rhus chinensis, p. 232; Saccharum pluviale, p. 130; Salicornia 
fruticosa, p. 56; Stachys hirta, p. 46; Stachys arvensis, p. 47J TillaeU 
procumbens, p. 57; Toxicaria rumphii, p. 90. Other nomina nuda 
in groups not covered by Index Kewensis are Lichen chinensis, Jun- 
germannia chinensis, Hypnum javanense, and Lycopodium varium. 
A few slight differences in names, due to typographical errors, are 
noted, such as Smilax sassaparilla, p. 248, instead of S. sarsaparilla; 
Hypochoeris radiata, p. 48, instead of H. radicata; Jasminum azoreum, 
p. 272, instead of /. azoricum; and Scorpiurus falcata, p, 73, German 
edition, instead of S. sulcata as it correctly appears in the original 
edition. 
Generic names originated by Osbeck are Cryptanthus, Tetradapa, 
and the nomina nuda Buxoides and Toxicaria, none of which have 
been used by subsequent authors in Osbeck's sense. They are not 
listed in any subsequent botanical work. 
Below are listed the species described by Osbeck that have been 
overlooked by most botanists. New combinations are made in a few 
cases. The original descriptions are quoted in full, and, where es- 
sential, an English translation of Osbeck's Swedish description or 
comment is added. At the end is given a summary of the species not 
listed in Index Kewensis, and those listed, but their places of publica- 
tion erroneously cited; the nomina nuda are menlioned above. 
I am indebted to Mr. Ivar Tidestrom of the U. S. Department of 
Agriculture for direct translation of some of Osbeck's comments and 
descriptions from the original Swedish, for comparison with the 
published German and English translations. 
Achyranthes chinensis Osbeck, Dagbok Ostind. Resa 205. 1757 = ? 
A. aspera L. 
This is probably a synonym of Achyranthes aspera L., or A. biden- 
tata Blume, if placed by Osbeck in the right genus. The description 
is inadequate, and apparently bracts or bracteoles were interpreted
