alternate divaricate branches with spreading leaves that have 

 reflexed tips and edges, solitary flowers on terminal peduncles that 

 are continuous with the branches, and an angular calyx with ovate 

 acute lobes. The herbarium of Thunberg contains three sheets 

 on which the name G. jasminoides has been written. That 

 marked a has only C. melampyrifolia, Lamk ; this is the plant 

 to which the description of G. jasminoides, Thunb., not of Linn., 

 applies ; it is the only Ghironia that has solitary flowers and an 

 angular calyx and that at the same time has divaricate branches 

 with spreading leaves that have reflexed tips and edges. The

that marked y has again G. tetragona, var. linearis, but with this 

 is associated another form of G. tetragona, Linn, f., which differs 

 from typical G. tetragona in having the leaves sub-elliptic instead 

 of ovate; this form has been considered by E. Meyer to be 

 referable to typical G. tetragona rather than to var. linearis. The 

 only characters in Thunberg's description of G. jasminoides that 

 are applicable to the species on his sheets fl and y are those of 'an 

 angled calyx ' and of ' solitary flowers on terminal peduncles that 

 are continuous with the branches.' What we find therefore is 

 that Thunberg has given a description of G. jasminoides which 

 is applicable only to G. melampyrifolia, Lamk ; that he has 

 associated with this species in his herbarium two forms of 

 6. tetragona, Linn, f., to which his description of G. jasminoides 

 is inapplicable ; that neither of the species named G. jasminoidss 

 by Thunberg can possibly be G. jasminoides, Linn. An examina- 

 tion of the specimens in various collections that are noted as 

 having been issued by Thunberg shows that he rarely distributed 

 as G jasminoides the species he described under that name. The 

 form that in most instances he gave away as G. jasminoides is 

 C. tetragona, var. linearis, E. Mey., which is represented in his 

 herbarium by sheet /3 ; in particular, it was this form that reached 

 the younger Linnaeus along with the original specimens of 

 O. tetragona and C. nudicaulis. This specimen of G. tetragona, 

 var. linearis, is still in the Linnean Herbarium, and still mis- 

 represents G. jasminoides, Linn., in that collection.
