Etymology: Helonomos = living in a marsh or bog, describ-

Sepala similia, inter se satis alte connata, nectarium vel tubum 
amplum formantia, apicibus patentibus; sepalo postico colum- 
nae dorsaliter adnato; sepalis lateralibus obliquis, antice paululo 
ampliatis. Petala sepalo postico partim agglutinata, basi leviter 
decurrentia. Labellum longe unguiculatum, ungue tubo sepalino 
omnino adnato, deinde sagittatum, marginibus in medio utrinque 
columnae lateribus agglutinatis. Columna erecta vel suberecta, 
dorsaliter sepalo postico satis alte adnata, apice libera, basi in 
pedem brevem apici ovari oblique producta; stigmata 2, vulgo 
separata, sese haud tigentia; rostellum breve, obtusum, ple- 
rumque in floribus autogamis dissolutum. Anthera ovato- 
lanceolata, cucullata, acuminata; pollinia lineari-clavata, viscidio 
parvulo, rotundo affixa. Ovarium fusiforme, sessile, haud tortum. 
Plantae terrestres, vulgo autogamae, graciles, spithameae vel 
ultra; radicibus cylindraceis, carnosis, pubescentibus; foliis basa- 
libus, petiolatis; caulibus e rhizomate brevi decumbenti erectis 
vel suberectis, remote pauci-bracteatis, apice laxe denseque spi- 
catis; floribus parvulis. 
Sepals similar, basal half connate into a more or less broadly 
tubular nectary, apical half with spreading segments; dorsal 
sepal adnate to back of column; lateral sepals somewhat oblique 
and extended basally. Petals for the most part, especially the 
inner margins agglutinate with dorsal sepal, basally somewhat 
decurrent. Lip with a long claw which is fully adnate to fused 
part of lateral sepals, then expanded into a sagittate blade, the 
sides of which agglutinate with column. Column erect to sub- 
erect, to base of clinandrium adnate to dorsal sepal, basally 
produced ina short, oblique foot on top of ovary, in front witha 
longitudinal groove; stigmata 2, commonly free with sides 
hardly touching one another; rostellum short, triangular, obtuse, 
mostly ruptured or dissolved in autogamous flowers. Anther 
ovate-lanceolate, cucullate, acuminate at apex; pollinia linear-
