None of the published figures of this common plant con- 

 vey a good representation of it. Both that in Andrews' 

 Repository and the Botanical Magazine represent the sepals 

 and petals as being wavy, which is the case only after the 

 plant begins to wither. The figure in the Prussian Horti- 

 cultural Transactions, under the name of Tylochilus flavus, 

 is dingy, and the flowers are too small. 



It is found wild in the tropical parts of America, where 

 from the fleshy stems the shoemakers obtain a kind of paste 

 or glue, which they use for the purposes of their art. 



The cultivator of Orchidaceous plants finds no difficulty 

 in keeping this in a healthy condition by potting it in well 

 drained turf, and treating it like any of the common Catase- 

 tums ; but the art of making it flower regularly and freely 

 is not at present understood about London. It is probable 

 that our houses for the cultivation of these plants are too 

 uniform in temperature and moisture. 



There are two varieties in our collections ; one which is 

 that now figured, has a branched inflorescence ; the other 

 has a perfectly simple one, with much larger flowers ; the 

 latter may possibly be the C. glutiniferum, a plant I am 

 unacquainted with. 



C. Wilmorei of the Flora Cabinet is nothing but C. punc- 

 tatam ill flowered. 



From Demerara I have an unpublished species collected 

 by Mr. Schomburgk, with a simple raceme, small flowers, and 

 a large fleshy oblong crest between the lateral lobes of 

 the lip ; this may be called Cyrtopodium cristatum and 

 thus defined. 



C. cristatum; racemo simplici, bracteis concavis patulis setaceo-acuminatis, 

 labelli lobis subeequalibus lateralibus erectis intermedio concavo integro 

 disco nudo, crista oblonga carnosa inter lobos laterales.
