nusve ovata vel obovata, obtuse leniterque cre-
nata, rigida, crassiuscula, venosa, attamen gla-
berrima, læte viridia, sæpe fusco maculata ; pe-
tiolus foliis 'longior, supra canaliculatus, basi

vàta. Antheræ oblongæ, quadrisulcatæ, bilocu-
lares, loculis apicibus pax’urn productis, perforatis
(Jig. 2). Pollen fiavum, trilobum.
Ovarium superum, liberum, subrotundum, quinquelo-
bum, staminibus obtectum. Stylus persistens,
capsula mature, plusquam duplo longior (Jig. 4),
et, staminum longitudinem multo excedens, infeme
declinatus, sursum reflectitur, apice incras-
sato, truncato (fig-. 5 ).' Stigma exiguum, quin-
quelobum.
Pericarpium : Capsula subrotunda, depressa, apice
umbilicata, pentagona, quinquelocularis, poly-
sperma, quinquevalvis ; dissepimenta valvis al-
ternantia, e centro radiata.
Placenta centralis, quinqueloba, lobis dissepimentis
alternantibuè et cum iis unitis (Jig. 6).

tubulosus (Jig. 8).
Embryo minutus, ovatus, fuscus.
Root perennial, woody, slender, creeping, here and there
fibrous..
Stem scarcely any.-
Leaves, all of them springing from the root, petiolate,
round, more or less oVate or obovate, obtusely
and slightly crenate, rigid, thickish, veined yet
smooth, deep green, often spotted with brown;
petiole longer than the leaves, canaliculated on
the upper surface, brownish-purple at the base,
and furnished with a stipule.
Scape generally solitary, much longer than the leaves,
from a span to nine inches high, erect, straight,
striated, here and there furnished with a bractea.
Flowers terminal, proceeding from every side, lax, pendulous,
and forming a raceme.
Peduncles about equal in length with the flower, beset
a t'th e base with lanceolate^ brown, striated
brae teas.
Calyx persistent, quinquefid, green, with the segments
acute, rose-coloured*
Corolla of five petals, white; having the petals a little
concave, spreading, round, veined.
Stamens ten, shorter than the corolla. Filaments yellowish
white, compressed, flat, broad, curved upwards.
Anthers oblong, with four furrows, two-
celled, the cells somewhat produced at the mouth,
' and perforated (fig . 2). Pollen yellow, three-
lobed.
Ovary superior, free, roundish, five-lobed, concealed
by the stamens. Style persistent, more than
twice as long as the mature capsule (fig. 4), and
much exceeding the length of the stamens; below
bent downwards, towards the apex pointing
upwards, the extremity itself thickened, truncate
(fig. 5). Stigma small, five-lobed.
Pericarp : A roundish, depressed capsule, umbilicated
above, pentangular, five-celled, many seeded, and
having five valves;- the dissepiments alternating
with the valves, and radiating from the centre of
the capsule.
Placenta central, five-lobed, with the lobes alternat-
incr with the dissepiments, and united with them
(fig. 6).
Seeds numerous, affixed to the central placenUe, and
closely imbricated (Jig- 5).
Aril (Garin.) membranaceous, reticulated, curved,
tubular (fig. 8).
I Embryo minute, ovate; brown.

Linneus’s observation is perfectly just, that “ Pyroliu omnes amant loca dura elumbrosn ; hmc semper m sjrlvis
