 Grisebach has, moreover, reduced C. Krebsii, Griseb. (1839), to 

 P. palustris, Griseb. (1845) ; the two plants are, however, 

 specifically separable, and Grisebach's reduction has led to the

Chironia nudicaulis, Griseb. (1845), has been treated as it was 

 in 1839, except that C. lychnoides, E. Mey. (1837), not of Berg., 

 has been correctly reduced to ft clongata. 



Chironia peduncular is, Griseb. (1845), has been treated as in 

 1839, except that G. kit i folia, E. Mey. (1837), has been correctly 

 reduced to this species. 



> Chironia maritima, Griseb. (1845), has had its natural character 

 vitiated by the reduction here of C. melampyri folia, E. Mey. 

 (1837), not of Lamk, which is a very distinct species. Grisebach 

 doubtfully recognised a new variety, ft ? frutescens, Griseb. 

 (1845) ; this variety is another distinct species, C. floribunda, 

 Paxt., Mag. Bot, xi., p. 237 (1844). 



Chironia jasminoides, Griseb. (1845), was treated as in 1839,

Chironia tetragona, Griseb. (1845), has been treated as in 1839 

 so far as the typical form is concerned. Grisebach has retained 

 the variety ft brevifolia, Griseb. (1839), which is the same thing 

 as C. uni flora, Lamk. He has, however, at the same time recognised 

 G. tetragona, var. linearis, E. Mey. (1837), which includes 

 C. uniflora, Lamk. The limits of both varieties are further 

 vitiated by the inclusion in ft brevi folia, Griseb., of G. jasminoides, 

 E. Mey. (1837), which is G. tabidaris, Page, and by the reduction 

 to y linearis, E. Mey. (1837), of G. viscosa, Zeyh., which is the 

 same thing as G. jasminoides, ft lychnoides, Griseb. (G. scabrida, 

 ft ligulifolia). 



Chironia scabrida, Griseb. (1815), has been treated as in 1839. 



Chironia perfoliata, Griseb. (1845), has been treated as in 1839, 

 except that G. speciosa, E. Mey. (1837), has been correctly reduced 

 to this species. 



Chironia arenaria, Griseb. (1845), as regards intention, 

 corresponds to G. arenaria, E. Mey. (1837). But of the two 

 forms distributed by Meyer as G. arenaria, only one was covered 

 Dy the original description. The description of C. arenaria given 

 by Grisebach similarly only covers one of the two forms, but in 

 tins case the form described is the one that Meyer did not 

 describe. C. arenaria, Griseb., as described, is therefore not 

 C. arenarm, E. Mey., but G. arenaria, ft mediocris.
