OsMoniYTUM. Caulis pseudobulbosus v. fusiformis apice 

 foliosus. Flores racemosi. Labellum adnatum ssepius 

 indi visum et cochleatum. Lindl. m Hook. Journ, 3. 81. 



1. E. cochleatu?n (Linn. L. p. 97.); foliis in pseudobiilbos ovales geminatim 



insidentibus oblongis acuminatis subundulatis, sepalis petalisque paulo 

 angustioril)us lineari-lanceolatis reflexis, labello cordato cochleato sub- 

 rotundo, colimma brevissima. West Indies. Tbere are two varie- 

 ties of this common plant; one with much paler flowers than the other. 



2. E. hracteolatum (Presl. L. p. 98.) ; pseudobulbis sidcatis, foliis oblon- 



go-lanceolatis obtusis, scapo tereti simplici, sepalis petalisque lanceo- 



latis patcntibuB, labello obcordato obtuso crenulato basi cristato. ■ 



Guayaquil. 



3. E. lancifoUiim (Pavon. L. p. 98. Bot. Reg 1842. t. 50.) ; pseudobulbis 



elongatis teretibus, foliis oblongo-lanccolatis acutiusculis, racemo stricto 

 terminali, sepalis petahsque lanceolatis acuminatis reflexis, labello cor- 

 dato oblato-ovato cochleato. Mexico. 



A. E. radiatum (Lindl. in Bot. Reg. misc. 1841. no. 123.); pseudobiUbis 

 ovatis compressis utrinque tricostatis triphyllis, foliis angustis elongatis 

 acutis, racemo denso multifloro, ovariis trialatis, sepalis liuearibus peta- 

 lisque lanceolatis patentissimis, labello cochleato crenato crispo, clinan- 

 drio trilobo laciniis lateralibus erectis carnosis intermedia tnmcata apice 



serrata. Mexico. Allied to E. cochleatum ; it has the same habit, 



but the pseudobulbs are strongly ribbed at the side, and the lip has the 

 margin crisp and crenated. The flowers are pale pea- green, with the ex- 

 ception of the lip, which is striated with bright deeper purple rays. 



5. E. venosiim (L. p. 99.); pseudobulbis angustis fusiformibus, foliis ensifor- 

 mibus scapi longitudine, racemo 4-5-floro, sepalis lineari-lanceolatis pe- 

 talisque angustioribus patentissimis, labello semilibero tripartito: laciniis 

 lateralibus ovatis acutis intermedia subrotunda apiculata multo majore, 



callo baseos lineisque tribus disci subramosis elevatis. ■ Mexico. 



Lip white, with raised violet veins. 



G. E. fragrans (Swartz. L. p. 97.) ; foliis in pseudobulbum angustum fusi- 

 forme (ssepiiis) solitariis lanceolatis apice rccurvis, scapo folio breviore, 

 sepalis lineari-lanceolatis petalisque ovato-lanceolatis acuminatis paten- 



tibus, labello subrotundo cuspidato lineato integerrimo. Tropical 



America everywhere. This plant is extremely variable ; and occurs in 



almost all collections from the east coast of the American Tropic . Pos- 

 sibly the Brasilian form, of which Gardner's G24 is an example, may be 

 a distinct species. 



/. E. ^ebim/z/zw (Lindl. in Bot. Reg. t. 1898.); rhizomate repente, pseudobulbis 

 ovalibus compressis, foliis solitariis oblongo-lanceolatis coriaceis, sepalis 

 petalisque lineari-lanceolatis cequalibus patentibus, labello subrotundo 



mucronato coclileato lineato integerrimo. Para. A dwarfer plant 



than E. fragrans, from which it is also distinguished by the form of its 

 pseudobulbs, its more leathery leaves, and its petals the same width as 

 the sepals. 



8. E. glumaceum (Lindl. in Bot. Reg. 1839. misc. no. 50. 1840. t. 6.) ; pseu- 

 dobulbis ovatis apice angustatis diphyllis, foliis anguste oblongis paten- 

 tibus, racemo terminali cylindraceo c squamis glumaceis acuminatissimis
