distinct species have been confused. The object of the present 
note is to clear up this confusion so far as the materials available 
anomalous in the genus. 
Miquel, some ten years later, reduced C. Thunbergit, Blume, to 
C. macranthum, Sw. (Prolusio Fl. Jap. p. 142), but was not able 
to add anything to the history of the plant, having only seen the 
unique original specimen. 
In 1876 Franchet and Savatier recorded the plant (Enum. Pl. 
Jap. ii. p. 40), as C. macranthum var. 23 ventricosum, Reichb. f., 
citing figures in two Japanese works, but giving no character. They, 
however, cite the Japanese name “ Ats’ mori so,” and mention two 
Japanese localities. 
In 1903 Pfitzer, in monographing the genus (Engl. Pflanzenreich, 
Arch. Pleon. p. 36), separated C. Thunbergii, Blume, giving 
C. macranthum, Franch. et Sav. nec Swartz, as a synonym, but he 
was only able to cite the original specimen at Leiden, repeating 
some of thie details of Blume’s figure. 
In 1905 Matsumura (Index Pl. Jap. ii. p. 242), included the 
whole of the plants previously mentioned under C. Thunbergii, also 
. Calceolus var. Atsumori, Morren (to which he gave no 
reference), and C. macranthum var. ventricosum, Reichb. f. 
Lastly, the writer, in 1908 (Orch. Rev. xvi. p. 186), separated 
the Japanese plant from the Siberian C. macranthum, Swartz, but 
followed Matsumura in calling it C. Thunbergii, Blume, a view 
which now proves erroneous 
The plant which Matsumura calls C. Calceolus var. Atsumori, 
Morren, is clearly C. Atsmori, Morren, described and figured 
in 1851 (Belg. Hort. i. p. 171, t. 21, fig. 1), from a specimen 
which flowered at the Botanic Garden, Ghent, and which is sai 
on, were pointed out. It has narrower sepals and 
petals than C. Thunbergii, Blume, while the staminode is also 
narrower, and without the acute basal angle shown in the latter. 
Thus the identity of the two remains somewhat doubtful in the — 
absence of more complete materials. 
We now come to the two Japanese figures cited by Franchet and 
Savatier. So moku Zusetsu, xviii. t. 83, is a figure in black and 
white, labelled C. macranthum, Sw. It is said to be indigenous in 
apan, but is very different from C. Thunbergii. Honzo Zufu, 
XXxix,, t. 19,is a coloured figure of a quite different plant, and
