Species ad 10, Indis orientalis, Archipelagi Malayani, Australim et, insularum maris Pacifici 
incole. Lindl. in Journ. Linn. Soc. iii. 61. — Benth. Fl. Austral. vi. 289.  Reichb. f. in Bonplandia, 
1857, 54 (Erie sect. excl. E. retusa); Otia Hamb. 54; in Linnea xli. 87; et ín Tvans. Linn.

Genus certe Erie valde affine eui adjunxit Reichenbach f., sed habitu, characteribus vegetationis, 
floribus minimis, perianthio sepius minus irregulari satis distinctum videtur. Rostellum 2-den- 
tatum a Lindleyo indieatum non in omnibus speciebus apparet. In sectiones 2 sequentes dividitur: 
1. Euphreatia, scapis e rhizomate juxta basin caulis foliati oriundis. Species typica, P. elegans, 
Lindl., ex India orientali, eum 2 v. 3 affinibus ex Archipelago Malayano. 
2. Plezaure, pedunculis in caule foliato axillaribus v. foliis delapsis lateralibus. Species plures, 
Archipelagi Malayani, Australie et ins. maris Pacifici incole. 4. Rich. Sert. Astrol. t. 2, 8

Oberonia Lindleyi, Brongn. in Duperr. Voy. t. 40 A, a Reichenbachio ad Ad: virentem, 
Bl., refertur, sed. cl minime iunt. Ex icone simillima est Phreatie limenophylaci ; 
pollinia depicta 2, stipitibus lateralibus rostello seu clinandrii margini affixa, evidenter erronea. 
40. Paehystoma, Blume, Bijdr. 316. (Pachychilus, Blume, Fl. Jav. Praf. 7 5; Orch. 
Archip. Ind. 97.)—Sepala squilonga, conniventia, lateralia nunc postico subsimilia 
pedi columns brevissimo adnata, nunc basi latiora eum pede columns magis evoluto 
mentum prominens formantia. Petala sepalo postico similia nisi paullo minora. 
Labellum pedi column: afüxum eique basi adnatum, nunc pede brevissimo subsac- 
catum, nune pedi longiori incumbens, dein erectum; lobi laterales oblongi, erecti, 
medius brevis, latus, retusus v. 2-fidus; discus medio laminis carnosulis instructus. 
Columna erecta, longiuscula, arcuata, subteres, basi in pedem brevissimum v. magis 
evolutum producta, superne clavata; clinandrium cavum, membranaceum, integrum 
v. sinuato-3-lobum.  Anthera terminalis, opercularis, incumbens, distincte 2-locu- 
laris, loculis plus minus perfecte 4-locellatis ; pollinia 8, cerea, in quoque loculo 4, 
ovoidea, apice brevissime v. vix inata, libera v. visco parco subcohzerentia. Capsula 
(in speciebus typicis) ovoidea v. obovoidea rarius oblonga, parvula, reflexa, costis acutius- 
culis parum. prominentibus.—Herbze tres, e rhizomate nodoso erectew, sub anthesi 
(v. omnino ?) aphyllz, caule simplici, basi b aginato, pseudobulbo demum 
interdum 1-2-foliato. Racemus simplex, floribus diocribus v. maj lis pendulis. 
Bracte: anguste, membranaceze, fere hyalinie. 
Species ad 10, quarum una Afric tropic, eter Indim orientalis et Archipelagi Malayani 
incole.  teichb. f. in Walp. Ann. vi. 462. 
Genus quale a Blumeo intelligitur in sectiones 2 dividitur forte melius pro generibus propriis 
restituendas :— 
1. Apaturia. Herbz (tanquam notx) omnino aphylle. Rhizoma crassum, nodosum, scapo ter- 
minatum.  Vagine et bractez erecte, anguste, scariose v. tenuiter membranacew, Flores sat 
numerosi, parvuli v. mediocres. Mentum sepe parum prominens. Pollinia breviter acuminata. 
Species plures Indiez et Arehipelagi Malayani. Z/ume, Orch. Archip. Ind. t. 10, 11 (Pachychilus). 
ArATURIA, Lindl. Gen. et Sp. Orch. 130. — Wight, Ic. t. 1662. 
2. Ipsea. Scapi aphylli, ad basin pseudobulbi cormiformis apice 1-2-foliati. Folia plieato-venosa 
non semper floribus coétania. Flores in racemo perpauci, sepe solitarii, majuseuli, mento valde 
prominente, Pollinia sepius longius acuminata, subeaudata. Species 2, quarum typica, e Zeylania 
et Peninsula Indica: Irsa, Lindl. Gen. et Sp. Orch. 124; Wight, lc.t. 1663; Bot. Mag. t. 5101, 
a Blumeo Orch. Archip. Ind. 29, t. 22, 23 ad Pachyckilum relata, Ei bene adjunetum videtur 
Pachystoma Thomsonianum, Reichb. f.; Bot. Mag. t. 6471, ex Africa tropiea. à 
41. Spathoglottis, Blume, Bijdr. 400.—Sepala libera, subrequalia v. lateralia paullo 
latiora, patentia. Petala sepalis similia nisi latiora interdumque longiora. Labellum ad 
basin column:e sessile, erectum, basi interdum saccatum ; lobi laterales juxta basin erecti, 
parvuli v. maj li, medius unguiculatus, ligulatus v. ovatus, ungue sspe supra lobos 
laterales utrinque dente v. auricula aucto; discus ad basin lobi medii tuberculatus v. 
eristatus. Columna elongata, semiteres, arcuata,
