greater part of the vegetative portion of the shoot. These 
again pass over into the linear bracts. This is illustrated in 
Fig. 50, a-e , each drawing being of the natural size. The 
leaves and bracts are fringed with stalked glands. The 
whole outer face, especially in the case of the bracts, is 
pubescent. Fig. 51 shows the margin of a bract, under the 
simple microscope, with the glands ; whilst in Fig. 52 a 
longitudinal section of a single gland is given. The structure 
of the scales calls for no special comment. They consist of 
a number of layers of thin-walled parenchymatous cells tra- 
versed in the median plane by a number of reduced, collateral, 
vascular bundles. The limiting epidermis is cuticularised 
except at the glands. No stomata are present, and the inter- 
cellular system is not well-marked. 
4. Morphology of the Flower . — Each individual shoot, as 
in Monotropa , terminates in an inflorescence, here crowded 
and bearing a large number of flowers. The inflorescence 
is built on the indefinite type (racemose), and Sarcodes 
would appear to be unique amongst Monotropeae in this 
respect. Monotropa and the others have the leading flower 
of the inflorescence terminating the axis. The proportion 
borne by the inflorescence to the rest of the plant is suffi- 
ciently shown in the portrait of the plant (Fig. 1). The 
closely imbricating scales of the c bulbous ’ portion pass over 
gradually into others, less fleshy, more loosely arranged, and 
somewhat narrower and longer (cf. Fig. 50, a, b , c , d , and e). 
These may be spoken of as the bracts ; each subtends a single 
flower. The lower flowers have fairly long pedicels, exceeding 
the length of the flower several times ; those above are 
gradually shorter. At the time when the shoot is elongating, 
and the spike of flowers being pressed through, and elevated 
above, the surface of the ground, each flower-bud is en- 
sheathed and protected by its subtending bract. The bracts 
themselves are hollowed out in a boat-like manner, as shown 
in Fig. 4. Later, when the flowers are about to expand, the 
bracts curve backwards and the flowers are exposed. The 
bracts persist until the ripening of the fruit. Like the scaly,
