OBSERVATIONS ON THE CUICHUNCHULLI. 
149 
Coralla pentapetala, bilabiata hy- 
pogyna, petalis thalamo insertis, 
inaequalibtis, marcescentibus ; labio 
inferiore monopetalo, calyce duplo 
triplove longiore, superne in lami- 
nam transversam vel labellum late 
obcordatum dilatato, medio angus- 
tato, earinato, basi paulo gibbo ; la- 
bio superiore tetrapetalo, calycem 
superante, lateralibus antrorsum fal- 
catis, mediis minoribus apice re- 
flexis. 
Stamina quinque, thalamo inserta, 
libera, approximata, filamentis, bre- 
vibus dilatatis, ovario adpressis, an- 
theras ad basin gerentibus, apice 
ultra antheras in membranam ova- 
tam stylum cingentem productis ; 
antheris bilocularibus, introrsum ri- 
ma longitudinali dehiscentibus ; 
squamulis glandulisve nectareis 
nullis. 
Ovarium superurn, sessile, unilo- 
culare, hexaspermum, placentis tri- 
bus parietalibus sepalis exterioribus 
oppositis, stylus I, persistens, apice 
recurvo ; stigma obtusum, laterale, 
labellum spectans. 
Capsula sphaerico-trigona, trival- 
vis, unilocularis, sutura loculicida ; 
valvis ab apice ad basin dehiscenti- 
bus, medio seminiferis, dispermis, 
saepius abortu monospermis ; semi- 
nibus globoso-ovatis, apice concavo- 
truncatis, nitidis, fuscis. 
Pedunculi axillares, solitarii, uni- 
flori, folio longiores, graciles hinc 
linea puberula notati, supra medium 
articulati, nec bracteolati. 
Corolla five-petaled, two lipped, 
hypogynous ; petals inserted on the 
thalamus, unequal, withering; the 
lower lip one-petaled, twice or thrice 
longer than the calyx, dilated at its 
upper portion into a transverse la- 
mina or broadly ohcordate labellum, 
narrowed and keeled at the middle, 
and slightly gibbous at base ; upper 
lip four-petaled, higher than the ca- 
lyx, lateral petals falcated forwards, 
middle ones shorter with their tips 
reflected. 
Stamens five, inserted on the 
thalamus, free, approximating ; fila- 
ments short, dilated, adpressed to 
the ovary, bearing the anthers near 
the base, produced beyond the an- 
thers into an ovate membrane sur- 
rounding the style ; anthers two- 
lobed, opening on the inside by a 
longitudinal cleft, and without any 
nectareal scales or glands. 
Ovary superior, sessile, one-cell- 
ed, six-seeded, with three parietal 
placentas opposite to the outer se- 
pals ; style one, persistent, bent 
downwards at its tip; stigma ob- 
tuse ; turned sideways towards the 
labellum. 
Capsule sphaerico-trigonal, three- 
valved, one-celled, with a loculi- 
cidous suture ; valves opening from 
tip to base, bearing two seeds in the 
middle, but more frequently, from 
abortion, one seed ; seeds globose- 
ovate, concavely truncated at apex, 
shining, dark brown. 
Peduncles axillary, solitary, one- 
flowered, longer than the leaf, slen- 
der, with a line of pubescence on 
one side, joined above the middle, 
without bracteae.
