of C. linoides, Griseb. (1845), is identical, so far as the plants are 

 concerned, with that adopted by Chamisso in 1831, for G. linoides, 

 Griseb. (C. gracilis, Salisb.), is G. vulgaris, ft intermedia, Cham. ; 

 var. ft longi folia, Griseb. (C. linoides, Linn.), is G. vulgaris, 

 a linoides, Cham.; var. y Zeyheri, Griseb. (G. emarginat.fi, Jarosz), 

 is G. vulgaris, y lychnoides, Cham. 



Ghironia baccifera, Griseb. (1845), has been treated as in 1839, 

 except that var. ft elongata, E. Mey. (1837), has been correctly 

 reduced to G. baccifera, Linn., and var. y dilatata, E. Mey. (1837), 

 has been correctly recognised as a distinct variety. 



Ghironia serpylli folia, Griseb. (1845), has been treated as in 

 1830, except that G. serpyllifolia, Eckl. (1830), has been correctly 

 reduced to var. y microphylla, Griseb., and that G. parvifolia, 

 E. Mey. (1837), has been also reduced here ; in this instance not 

 quite correctly, because only Drege's Van Staadesberg gathering 

 belongs to this variety. 



Schoch in his monograph of Ghironia, published in 1003 (Bot. 

 Gentralbl. Beih., xiv., pp. 175-242), has described so carefully the 

 various forms recognised, and has quoted specimens so fully in 

 support of his conclusions that it is unnecessary to do more here 

 than refer briefly to the points as to which these conclusions do 

 not coincide with the results arrived at in the course of the present 

 study. In not a few instances the discrepancies between Schoch's 

 conclusions and those now stated amount to no more than a 

 difference of opinion as regards the limitation of particular species 

 or varieties. It will, however, be found that the authorities 

 quoted by Schoch under individual species have been cited on 

 bibliographical principles rather than as the result of a study of 

 the specimens dealt with by the authors themselves ; this circum- 

 stance somewhat lessens the utility of his citations for taxonomic 

 purposes. 



Ghironia baccifera, Schoch (1903), includes G. baccifera, Linn.,* 

 *nd G. baccifera, var. grandiflora, Griseb. Only one variety. 

 ft dilatata, Schoch, has been recognised ; this variety is not 

 identical with ft dilatata, E. Mey., since it also includes G. bacci- 

 fera, var. Burchellii, a form referred by other authors to G. bac- 

 cifera, Linn., proper. 



Ghironia serptjlli folia, Schoch (1903), has not been treated 

 precisely as it was by Grisebacb, since Schoch has only admitted 

 two forms, corresponding to ft laxa, Griseb., and y microphylla, 

 Griseb. It is left doubtful which of these may be the original 

 O. serpyllifolia. 



Ghironia pubescens, Schoch (1903), is G.pubescens, Bak (1882), 

 which does not, however, appear to be specifically separable from 

 C. madagascariensis, Bak. (1881). 



Ghironia jasminoides, Schoch (1903), is recognised on biblio- 

 graphical in preference to morphological considerations Among 

 the specimens cited, Ecklon n. 176 is G. scabnda, yar. lW«/™*
