In considering the specimens in the Linnean Herbarium, it has 

 to be recollected that in the first edition of the Species Plantarum 

 (1753), pp. 189, 190, Linnaeus enumerates seven Chironiae, four 

 of which, G. trinervia (Exacum), G. angularis (Sabbatia), 

 6'. campanulata (Sabbatia), and G. dodecandra (Sabbatki\axe not 

 members of the genus as now defined, and are not African. The 



frutescens

are now included in Chironia. In 1760 (PL Afi 



(Mt 



specimen

tissa, p. 207) he described a fourth, which he believed to be 

 C. lychnoides as described by P. J. Bergius in 1767. To these the 

 younger Linnaeus added in 1781 (Supply p. 151) G. nudicaulis 

 and G. tetragona. In 1756, however {Gent., iL, p. 12), Linnaeus 

 had published, as G. caryophylloidcs, a species which he subse- 

 quently included in C f . frutescens (Or phium frutescens, E. Mey.) ; 

 it is treated above as only a variety of this last species. 



The register which Linnaeus kept of his specimens shows that 

 in 1753 only one of the true Ohironiae enumerated in the Species 

 Plantarum was represented in his herbarium. This was 

 G. baccifera ; the specimen named by himself is still there, accom- 

 panied by a second named by his son. The herbarium also has 



named by Linnaeus himself, described as G. lych- 

 specimen represents a variety of his own G. jas- 

 minoides, and is not G. lychnoides, Berg. The specimens from 

 which the younger Linnaeus described G. nudicaulis and G. tetra- 

 gona, both named by their author, are also present ; the latter 

 represents a valid species ; the former is only another local form 

 of G. jasminoides, Linn. 



There is a specimen in the Linnean Herbarium named G. jas- 

 minoides, but the name was not written by Linnaeus or by his son ; 

 and the plant itself, which is a variety of G. tetragona, Linn, f., 

 does not accord with the original description of C. jasminoides. 

 That description is unusually full, and is so precise that, notwith- 

 standing the considerable accession of new forms since 1760, it is 

 still applicable to only one of the known species of Chironia. 

 The plant on which the description was based was collected by 

 Burmann ; and whilst it is true that, so far as is known, no speci- 

 men now exists on Avhich Linnaeus himself has written the name 

 G. jasminoides, there still exist specimens, collected by Burmann, 

 of a plant to which alone the Linnean description is applicable, 



that have been named O. jasminoides by contemporaries of 

 JLmnaeus. 



The absence from the Linnean Herbarium of any specimen of 

 O. linotde$Mt the time that this name was published compels us to 

 seek elsewhere for the evidence required to establish the identity
