238 MONOGRAPH OF THE GENUS PYROLA. 
This remarkable species, although wholly destitute of 
real leaves, is not, strictly speaking, leafless ; their place is 
supplied by a kind of foliaceous scales, of a greenish colour, 
coriaceous, lanceolate, acute, entire. In some of the fine 
specimens preserved in the Banksian Herbarium^ an ap- 
proach to leaves may be distinctly observed. This circum- 
stance appears to me to confirm the opinion entertained by 
some botanists respecting the nature of the scales on the 
scapes of Monotropa, OrobancJie, OrcJiides, &c. consider- 
ing them as analogous to leaves, or, more properly, abortive 
ones.
