xiv CHARACTER NATURALIS. 
Co.umna genitalium e stylo staminibusque in corpus solidum conferrumi- 
natis conflata, ita ut ille ejusdem faciem labello obversam, hzc dorsalem 
constituant ; cum ovario continua et recta, v. pede plus minus producto 
in ejusdem verticem obliqua v. prona; ssepius carnosa et indivisa, ali- 
quandó tenuissima petaloidea, feré semper sepalis brevior, rarissime* 
ultra perianthium long? extensa. 
STAMINA 3, sepalis opposita, centrali tantum antherifero, nisi in Cypripe- 
deis quarum stamen intermedium dilatatur dum abortat et lateralia an- 
theris coronantur; sæpiùs conferruminata, quandoque tamen lateralibus 
sterilibus omninó liberis, carnosis v. petaloideis. ANTHERA nunc 1-lo- 
cularis, szepius bilocularis ; loculis simplicibus v. 2-4-locellatis ; solitd 
per 2 lineas medias dehiscens, nunc facie loculorum separabili et de- 
Hexà bilabiata; connectivo aut membranaceo inconspicuo, aut car- 
noso et in cristam cornuve extenso; erecta et columnam terminans, v. 
dorsalis cum stigmatis dorso subparallela, v. opercularis, in clinandrium 
s. columpz apicem excavatum prona, PorrEN nunc pulvereum, nunc in 
granulis adherens, nunc in cuneolos materie elasticà colligatos, nunc in 
pollinia s. massas cereaceas numero definitas conferruminatum.  Por- 
LINIA aut libera aut s:piüs materie supra dicta elasticà diaphaná (cau- 
diculá) connexa, ejusque ope stigmatis apici s. glandule affixa. 
Ovarium inferum, 1l-loculare, e carpellis 6 constans, quorum 3 petalis 
opposita placentas didymas polyspermas parietales gerunt, stigmatibus 
nullis, dum 3 sepalis opposita in stigmata totidem producuntur. 
SrvLvus nullus distinctus nisi in Cypripedio Neotteisque quibusdam, sed 
filamentis conferruminatus. SrrGMATA szpius in discum mucosum ca- 
vum nunc prominentem confluentia; dorsale in marginem superiorem 
glandulis 1-2 in Vandeis Neotteisque separabilibus instructum, sepe in 
rostellum elongatum v. plicatum, v. in bursiculas excavatum productum, 
quandoque in brachia bina parallela v. divergentia canaliculata, ope 
membrane s. rostelli plicati connexa extensum ; lateralia in plurimis 
obsoleta, nunc basi labelli appendicis s. lamellarum callorumve forma 
adnata. 
CaprsuraA raro indehiscens, carnosa, siliquiformis, sepissime in valvis 6, 
siccis, ligneis, rigidis, quarum 3 seminifera solubilis. 
SEMINA plurima, minutissima, testà laxA reticulatà, rard atrà crustaceá, 
nonnunquam in glam circularem compressà; embryone exalbuminoso, 
solido, carnoso; chalazà apici seminis proximá ideoque radiculà hilo 
contiguá. ` 
The general structure of Orchidaceæ, briefly embodied in the foregoing 
description, has been treated of at such length in the prefatory matter 
of the Illustrations of Orchidaceous Plants, that it is unnecessary to do 
more than refer the reader to that work. I must, however, take the 
opportunity of correcting one part of the theoretical view which was there 
taken of the structure of the column. While, in common with Dr. 
Brown, I regarded the stigma as really consisting of three parts, usually in
