Gen. Char. Calyx inferior, of 4 or 5 coloured sepals (see fig. 2''. 
Corolla permanent, of 4 or 5, inversely egg-oblong, upright, petals, 
slightly cohering, and concave at the base (see fig. 1 }. Filaments 
(see fig 3.) 10, or 8, upright, strap-shaped, flatfish, shorter than the 
corolla; the 5 or 4 alternate ones rather the smallest. Anthers 
kidney-shaped, upright, of 1 cell and 2 valves. Germen (see fig. 3.) 
superior, egg-shaped, with 5, or 4, furrows. Stigma orbicular, 
peltate. Capsule (fig. 4.) superior, roundish, with 5, or 4, furrows, 
and as many cells and valves, with a partition (dissepiment) from 
the centre of each valve ; and a spongy central column (placenta) 
of as many angles (see fig. 5). Seeds (fig. 6.) very numerous, mi- 
nute, oval, enveloped in a membranous reticulated tunic, or arillus , 
greatly elongated at both ends. — Herbaceous parasitical plants, 
with leafless scaly stems. 
The terminal flower, which in some species is the only one with 
10 stamens, 5 sepals, and 5 petals, determines the class, as in 
Adoxa, t. 42. 
Distinguished from other gen,era, in the same class and order, by 
the calyx of 4 or 5, coloured sepals ; the corolla of 4 or 5 petals, 
slightly united at the base ; the simple cylindrical style ; and the 
4- or 5-celled, 4- or 5-valved, many-seeded capsule. 
One species British. 
MONO'TROPA HYPO'PITYS §. Yellow Bird’-nest. Yellow 
Pine-sap. 
Spec. Char. Flowers in a terminal cluster, at first drooping ; 
lateral ones with 8 stamens; terminal one with 10.

* From monos, Gr. one ; and trepo, Gr. to regard ; alluding to the Linmcan 
principal of chiefly attending to the single terminal flower for the determination of 
the class and genus in preference to the lateral ones, as exemplified in the present 
genus. Withering. t See fol. 37, n. +. f See fol. 339, a.
