li. 312 (1837). Arnebia densiflora Ledeb. Fl. Ross. iii. 140 (1846- 
51). Apparently this beautiful plant has never been properly 
christened. Its large golden flowers must excite the admiration of 
those who know it i fa the field. 
EcHIUM MICRANTHUM Schousboé, Vextr. Maroko 75 (1800). De 
Coincy, Journ. de Bot. xvi. 229-231 (1902), in his detailed discussion 
of the group has given convincing evidence that E. sabulicolum 
Pomel and E. decipiens Pomel, Nouv. Mat. Fl. Atl. i. 90 & 91 (1874) 
are mere variants of his E. confusum, 1. c. xiv. 298 (1900); also 
that E. micranthum Schousboé (I. ¢.) “ est probablement la forme 
femelle de |’ EF. confusum,” |. c. xv. 312 (1901), and again, “ Les 
formes femelles 4 petites corolles et 4 étamines paraissent aussi 
fréquentes dans la variété decipiens que dans le type. C’est alors le 
micranthum,” 1. ¢. xvi. 231 (1902). This variation from the normal 
hermaphrodite flowers is a well-known phenomenon in Echium 
vulgare, cf. Knuth Handb. FI. Poll. ii. 133 (1909); and de Coincy 
has also discussed its occurrence, Bull. Herb. Boiss. ser. II. i. 190 
(1901). Reference to the original description of EF. micranthum, 
however, shows that Schousboé must have had perfect flowers at 
hand; and it seems to me that his plant was, in all probability, the 
maritime form described by Pomel, Nouv. Mat. Fl. Atlan. i. 91 
(1874), as EH. sabulicolum which de Coincy, Journ. de Bot. xvi. 229 
(1902), considers as ‘‘ une forme ”’ of his EF. confusum “ mais il ne 
parait pas opportun d’établir ici une variété qui n’aurait que des 
limites par trop incertaines.”” But he makes the combination £. 
confusum Coincy, var. decipiens (Pomel) Coincy (I. c. 230), dis- 
tinguishing the variety principally by its annual duration and 
simple erect stem. However, this is contrary to the International 
Rules, according to which the earliest specific name must be re- 
tained. Therefore I am making the necessary combinations; and 
since I agree with de Coincy on the relationships of the variants of 
this plant, as completely delineated by him (I. ¢.), it has seemed 
unnecessary to repeat them here.
