ser. 5, xviii. 374 (1873), the type of which, collected on the Isle of 
Bourbon by Richard, is now in the Gray Herbarium. Other speci- 
mens of F. flexuosa at hand show the species to have a fairly wide 
range of variation as to leaf-contour, in some cases reaching the short, 
subcordate, conspicuously cuspidate-caudate form of Klatt’s type, in 
others passing to elongate lance-oblong shapes more or less cuneate at 
the base. 
Cetmista Cass. Dict. Sci. Nat. vii. 356 (1817). This genus of the 
Senecioneae was founded by Cassini upon a single South African 
species, which he called C. rotundifolia and which later proved to have 
been the plant previously named Arnica tabularis by Thunberg, Prod. . 
Fl. Cap. 154 (1800). The genus Celmisia, thus having been originally 
based upon a single species, there can be no question as to its type. 
Furthermore, the name has not been mentioned in the lists of nomina 
conservanda or nomina rejicienda, so it must take its course under the 
rules of priority. Cassini subsequently, Dict. Sci. Nat. xxxvii. 259 
(1825), included in his genus a plant collected by Gaudichaud in 
Australia, namely C. longifolia Cass., a plant belonging to the Astereae. 
When the Compositae were treated by DeCandolle he unfortunately 
took this latter, Australian plant as the type of the genus, and referred - 
the original South African species to a newly named genus, Aleiope 
DC. Prod. vy. 210 (1836). This was, of course, contrary to the clause 
of Article 45 of the International Rules, which reads: “ If the genus 
contains a section or some other division which, judging by its name 
or its species, is the type or the origin of the group, the name is re- 
served for that part of it.””, DeCandolle’s treatment has been gener- 
ally accepted and perpetuated until the present day. It is true, Dr - 
Otto Kuntze noted the inconsistency and restored Celmisia to ts 
original application, but he referred the Australian and New Zealand 
element of the complex to the genus Aster, a reduction not likely to be 
generally followed upon taxonomic grounds. The current Inter- 
national Rules appear to call for the following revision of the nomen- 
clature in the genera concerned.
