tirely different habitats from the ones in which they 
originally grew, and Morris and Eames (l.c. p. 8) said 
that C.parvijlorum was so adaptive and hardy that it had 
spread from its native swamp to upland wood and grassy 
bank. We do not recall any case where a species exists 
as such because of its “habitat” or “cultural require¬ 
ments.” 
Fern aid (Rhodora 28 (1926) 168) separated var. plan- 
ipetalum “from both C.parvijlorum and C.parvijlorum 
var. pubescens (Willd.) Knight by its short and compara¬ 
tively broad, flat, usually purplish petals, by the relatively 
shorter and broader upper sepal with less acuminate or 
elongate tip and with rounded rather abruptly narrowed 
or subcuneate base, and by the cordate staminodium. 
He made the following observations: “In its broad flat 
petals C.parvijlorum var. planipetalum strongly suggests 
the Eurasian C. Calceolus L. and such a plate as that of 
Redoute,jLes Liliacees , i. t. 19 [C. Calceolus] looks almost 
intermediate between C. parvijlorum and var. planipet¬ 
alum ; and in some Eurasian specimens of C. Calceolus the 
staminodium shows a very strong tendency to be cordate 
[see Sowerby English Botany 9 (1869) t. 1; Keller and 
Schlechter Monographic und Iconographie Orchideen 
Europas. . . 1 (1927) t. l,no. 8; H.Correvon Album des 
OrchideesdeVEurope... (1899)t. 10; Stein’s Orchideen- 
buch (1892) 177, fig. 59]. In both C. Calceolus and C.par¬ 
vijlorum var. pubescens , however, the staminodium is 
longer-stalked than in true C.parvijlorum and var. plani¬ 
petalum and the sepals and petals of the Eurasian plant 
are more consistently purple than in the American series. 
They are very close, however, and it need not be surpris¬ 
ing if, with better knowledge of the variations of the two 
series, the Eurasian and American plants are eventually 
treated as one polymorphic circumpolar species.” (Pro¬ 
fessor Ames shares with Fernald this latter viewpoint).
