which Capura L. Mant. ii. 149 (1771) has been subordinated as a 
nomen rejiciendum. Although, by a strict interpretation of Art. 57 
of the International Code, it might be possible to conserve the later 
Wickstroemia Endl., since it differs by a single letter from W2k- 
stroemia Schrad. (commonly but not originally spelled Wick- 
stroemia), such action is very unlikely to meet with favor among 
botanists, and is certainly opposed to the spirit if not the letter of 
the Code, since it could not fail to lead to uncertainty and con- 
fusion. Furthermore both genera were named after the same 
botanist, whose name as written by himself was Wikstrém, and it 
seems best to consider Wikstroemia and Wickstroemia as mere 
variant spellings of the same name. 
Although the name to be used for the large genus of the Thyme- 
laeaceae now known as Wickstroemia Endl. is not directly at issue 
here, it may be noticed in passing. The obvious intent of the 
International Congress was to forestall unnecessary changes by 
making Wickstroemia Endl. a nomen conservandum over Capura 
L.,) in the belief that the earlier Wikstroemia of Schrader had been 
definitely disposed of in synonymy; that is, to do away with the 
necessity of replacing Wickstroemia by Capura merely because of 
the priority of the latter. The necessary recognition of an earlier 
Wikstroemia essentially alters the circumstances of the case, and 
should certainly lead to the adoption of the earliest name, Capura 
L., rather than to the use of the third and latest name (Dzplo- 
morpha Meisn. Denkschr. Regensb. Ges. iii. 289 (1841)), which 4 
too strict interpretation of the letter of the Rules might seem to 
indicate. In any case, it is clear that by the International Rules 
the name to be adopted for the Theaceous genus generally caile¢ 
Laplacea or Haemocharis is Wikstroemia Schrader. The valid 
‘species of this genus, material for the revision of which is chiefly to 
be sought in European herbaria, are the following:
