Monotropaceae with Reference to Ericaceae 91 



In P. elliptica, the lobes of the sepals are much shorter than 

 in P. rotundifolia; they are triangular, ovate-acute, about 2 mm. 

 long, not one-fourth the length of the petals. 



In P. secunda, the calyx lobes are "oval or elliptic, 1 mm. 

 long, rounded at the apex" (72). 



In P. minor, the calyx lobes are "triangular-acute or short- 

 acuminate, as broad as long" (72). 



In P. chlorantha, the calyx lobes are "triangular, acutish 

 or obtusish, about as broad as long" (72). 



In P. aphylla, the calyx lobes are "ovate-triangular, acute, 

 as long as broad, or slightly longer, about 1.5 mm. in length" 



(72). 



In Moneses uniflora, the calyx lobes are ovate, obtuse, 3 mm. 

 long, with numerous unicellular hairs along the margin. 



In Monotropa hypopitys, the sepals are distinct, not united. 

 They consist of 2-3 narrow bract-like structures about 6-8 mm. 

 long, yellow in color, with a few long unicellular hairs on the 

 upper surface and numerous ones on the margin and lower 

 epidermis. 



In Monotropa uniflora, there are 2-4 white bract-like sepals, 

 1-1.5 cm. long, which are not united. These are glabrous, 

 except for a few hairs on the upper surface. The margin begins 

 to show a slight irregular toothing near the axis. 



In Sarcodes sanguinea, there are five fleshy oblong-lanceolate 

 crimson sepals about 2 cm. in length. Oliver states that these 

 are distinct, but the writer finds that they are very slightly 

 united at the base, and have a fimbriolate margin and the entire 

 outer surface covered with glandular hairs. 



In Pterospora andromedea, the sepals are brownish, united; 

 the lobes are lanceolate, about 4 mm. in length, and are glandu- 

 lar pubescent. 



In Pleuricospora fimbriolata, the four whitish sepals are sep- 

 arate lanceolate, 8-9 mm. long, and have a fimbriate margin. 



In Schweinitzia odorata, the sepals are five, purple or purplish 

 brown, becoming lanceolate, 8-12 mm. long, usually acute. 



In Allotropa virgata, there are five broad distinct white sepals, 

 "orbicular ovate to rhombic ovate, 4-6 cm. long, erose" (72). 



In Newberrya congesta, the sepals are two brownish distinct, 

 linear or nearly so (72). 



In Newberrya spicata, the sepals are two, brownish-"spatulate, 

 erose-fimbriate" (72).
