broadly oblong-lanceolate. Petals 4-9 cm. long, narrowly 
linear-lanceolate, flat or spirally twisted. Lip pouch¬ 
shaped, 1.5-6.3 cm. long, dull cream-colored to golden- 
yellow, rarely approaching white, commonly veined or 
spotted magenta-purple. Staminode bright yellow, spot¬ 
ted with red-madder-purple, varying from spatulate or 
oblong-linear with a slightly cordate base to triangular- 
ovate with a somewhat auricled base and obtuse apex, 
sometimes concave or conduplicate, supported by a thick 
fleshy stalk. 
Variety pubescens differs from the species in its poly¬ 
morphic tendency, varying in the staminode, in size of 
the flowers and in coloration of the flowers. It also differs 
from the species in its geographic distribution, C. Calceo- 
lus being a Eurasian plant while var. pubescens is con¬ 
fined to North America. Flowers of the more northern 
and intermediate forms of var. pubescens approach C. 
Calceolus very closely and are strongly odoriferous as in 
the species. 
Variety pubescens is not restricted to any specific 
habitat. In the North it is commonly found in Arbor 
Vitae, hemlock, spruce, and tamarack swamps and bogs. 
Throughout its range it is found in sphagnum bogs, 
thickets, meadows, pastures, open deciduous woods, 
rocky dry wooded slopes, low moist woods, and open 
swamps. The variations found in the plants are probably 
in part due to their various habitats, as well as to their 
geographic location within the range of the variety. For 
example, the flowers of the plants found in Louisiana and 
Mississippi are much larger, on the average, than those 
of the plants found in Newfoundland. Variations as to 
color of the flowers and size of the plants may also be 
partly attributed to the environment of the plant, such as 
soil conditions, precipitation, temperature and exposure. 
The geographic distribution of var. pubescens is from
