526 CLXIX. ORCHIDEJE. [Epidendrer., 
Benth., O. montane subsimilis sed multo validior (6-pedalis), foliis lato-laneeolatis, racemo plurifloro 
bracteis latis laxis rigidis; in monte Moses Jamaice legit Syme. 3 0. monophylla, Benth. (Trigoni- 
dium monophyllum, Griseb. Fl. rit. W. Ind. 629), caule 1-foliato, cc-vaginato, 1-2-floro. Perian- 
thium majus et magis expansum quam in precedentibus, sed florum structura eadem, nec generice 
separanda.

dium cum labelli ungue in tubum connata, superne libera, erecta, semiteres,exalata ; clinan- 
drii lobus postieus latus, obtusus, oblique truncatus, laterales erecti, falcato-ligulati.

septo longitudinali divisis quasi 4-locularis ; pollinia 4, lato-ovata, parallele compressa, 
utrinque obtusa, inappendiculata v. vix granulis paucis connexa. Ovarium in collum 
longiuseulum superne latius productum. Capsula . . .—Herba epiphytica, caulibus in 
rhizomate repente nanis leviter i &is vix pseudobulbosis apice 2-foliatis. Scapi 
foridi e rhizomate aphylli, vaginis laxe imbricatis membranaceo-scariosis in bracteas 
beuntibus obtecti. R brevis, simplex, terminalis, densiflorus. Flores mediocres, 
conferti, pedicellis longiusculis tenuib Bractez anguste, scariose. 
Species 1, Mexicana. Lindl. Gen. et Sp. Orch. 158. Characterem ex specimine Hartwegiano in

bulbus apice 2-foliatus et raeemifer dieitur dum in specimine Herb. Lindl. seapi omnes aphylli, 
pseudobulbis 2-foliatis omnino ananthis. An genus potius ad Dendrobi: juxta Bulbophyll 
amandandum?

subrequilonga, patentia, lateralia basi obliqua, brevissime connata. Petala sepalis sub- 
similia. Labelli unguis erectus, cum columna connatus, lamina patens indivisa. Columna 
fere ad apicem cum labello connata. Anthera et pollinia Epidendri.—Caules elongati, 
foliati, nec carnosi, nec pseudobulbosi. Folia disticha, vaginis caulem obtegentibus. 
Racemi ad axillas subsessiles, breves, fasciculif pauciflori v. ad florem. unicum 
reducti. Flores parvuli, breviter pedicellati.

(Ponera. adendrobium, Reichb. f. in Flora, 1865, 278). Genus adhue dubium, Epidendro et Ponere 
affine. Habitus et inflorescentia a priore valde discrepant et. sepala lateralia basi mentum breve 
formare videntur minus tamen prominens quam in Pomera. Flores in speciminibus nostris rite 
examinare nequimus, et genus v. sectio ulterius scrutandum.
