This noble species of Cycnochcs has lieen introduced from Pcmerara by Messrs. Loddigctf, 

 in whose collection the annexed figure was taken; it was also sent to Berlin in 183<i from 

 Mnraeaybo by Mr. Mont/, a naturalist in tliat country, from the produce* of whose plant* Dr. 

 Kiotzsch obtained tlic flowering specimen described in the work above quoted ; and I have seen 

 a flower of it in the possession of the Messrs- Kollisson* of Tooting, who received il from Mr, John 

 Youell. Nurseryman. Great Yarmouth. In every case of its. blossoming; three flower* were obtained* 

 so that such may be supposed to be the number usually borne bv each raceme. 



In many respect?* il resemble* the Cycnochcs ventricosum figured in Mr. HattnianV princelv 

 work on the Orchidacca* of Mexico and Guatemala, but it differs in the flowers being much larger, 

 the raceme shorter and less graceful, tlie sepals mid petals broader and not so acute, and especially 

 in the form of the lip, which in nearly sessile, obovatc and acute, not ovale and acuminate, green 

 not while, with the broad green callosity at the base far larger and differently formed. 



In the stem and lea v ft* this plant does not sufficiently differ from the two other species of tile 

 genu* to rcquiiv a particular description* The hackmk springs from the upper [tart of the stent, 

 from among some dry, furrowed, acute, close-pressed scales, ami usually bears three flower*, of a 

 uniform yellowish green colour, nearly six inches in diameter, and by their weight bearing down 

 the peduncle in a slight degree, so as to acquire a nodding, not a pendulous, pusitiun* Of the 

 .sepals the lateral ones are oblong, narrowed to the |>oint, but not acuminate, a little- longer than 

 the labellnm, at the back of which thoy are placed almost parallel with each other ; the intermediate 

 one is narrower, obtuse, a little spreading away from the column, whose curve it follows, except 

 near the end. where it 1* somewhat recurved. The petals are broader than the lateral sepals, but of 

 ihe same form, except that they are slightly falcate, with iheir concave edge next the lip. toward* 

 which they are turned, so that the Mower has its parts expanded in two opposite directions: lite 

 lateral sepals, petals, and lip upwards, and the intermediate sepal downwards. The LIP stands 

 erect at the back of the flower, is about two inches and a half long, and nn inch and a nuartcr wide 

 in the broadest part ; in texture it is Ann and fleshy ; in colour it is deep green ni the base, and 

 a yellowish green every where else : in form it is widest and very convex u little above the middle, 

 from which it is regularly orate ns far as the point: below the middle it narrows, and become* 

 concave with thick, round, elevated, recurved edge** aad at the base it is contracted into a very shori 

 thick fleshy unguis ; above (he unguis, and across it, is seated a thick, green, somewhat triangular 

 but rounded callosity, scarcely a quarter of an inch deep. The column is about an inch and three* 

 quarters long, very slender, green, wide at the base, tapering through the greater part of its length, 

 and flattened out at the apex, where il terminates in three narrow fleshy teeth curved over ihe back 

 of the anther, the middle one being the narrowest ; it bends away from the lip »o gracefully, that 

 the two taken together almost describe the segment of a circle. 



The flowers are from five to eight inches in diameter, and are dclieiously fragrant.
