Monotropaceae with Reference to Ericaceae 89 



are narrower than the scales below, and are about 10-12 mm. 

 in length, shorter than the flower, and are quite numerous at 

 the base of the flower. They are much thinner in texture than 

 in M. hypopitys. No hairs are present in these. The margin 

 becomes somewhat irregularly toothed toward the apex. 



In Sarcodes sanguinea, the flowerstalk is 1-5 dm. in length. 

 The flowers are numerous, borne in racemes, each on a pedicel 

 that is pubescent with short glandular hairs. Those of the 

 lower flowers are longer than those of the upper. The bracts, 

 crimson in color, become much narrower than the lower scales 

 and are longer than the flowers, 2.5-6 cm. long. The bracts 

 ensheathe the buds as they come above the surface of the ground. 

 Later they curve backward. The whole outer surface and the 

 margins of the bracts are covered with glandular hairs. Near 

 the apex, the margin appears somewhat toothed. 



In Pterospora andromedea, the flowerstalk is 3-1 1 dm. in 

 length. The numerous flowers are borne in racemes. The 

 purplish brown bracts are linear, about 5 mm. in length, as 

 long as, or longer than, the pubescent pedicels. Numerous 

 glandular hairs are present on the margin and lower surface. 



In Pleuricospora fimbriolata, the flowerstalk is 1-2.5 dm. 

 long. Numerous flowers are borne in a raceme. The brownish 

 bracts are smooth, 1-2 cm. long, have a fimbriolate margin. 



In Schweinitzia odorata, the flowerstalk is 5-1 1 cm. long. 

 Flowers are borne in a dense terminal raceme. Bracts are 

 purple or purplish brown and about 8 mm. in length. 



In Allotropa virgata, the flowerstalk is 1-5 dm. long. Numer- 

 ous flowers are borne in a raceme. The whitish bracts are 

 linear-lanceolate, 1-2.5 cm. in length, narrower than the lower 

 scales. 



In Newberrya congesta, the flowerstalk is 1-5 dm. tall or less, 

 terminated by a "corymbiform glomerule"; "scales ovate brown- 

 ish — the upper ones narrower, all obtuse irregularly erose" (72). 



In Newberrya spicata, the flowerstalk is mostly less than 

 1 dm. tall, terminated by a dense spike; scales oblong, brownish, 

 sometimes acutish erose fimbriate (72). 



In typical Ericaceae, the inflorescence is generally racemose, 

 or condensed to a corymb or umbel as in Rhododendron, or 

 solitary axillary as in Kalmia hirsuta, Phyllodoce, Cassiope, 

 Chiogenes. In the Pyrolaceae and Monotropaceae, Pyrola,
