656 ORCHIDES. 



ZYGOPETALUM. 



Very distinct one nowered species, ihe leaves of which I liave not seen. Sepals 

 IVa— 1'/4 inch long. straw coloured. the lower straight, coneave and deflexed , the 

 upper erect, roiled bocli ot the j^oint. pressed close ilie peials . and with them forra- 

 ing an arch over ihe colunin and lip. Lip has a nearly circular outiine. but is so 

 concave, as uol to present that form until flattened : it is slighily trilobed, of a deep 

 duU. velveiy purple colour, white al tbe base. a roundish oblong , yellow appendage, 

 which adheres to the lip and is divided at the edge inlo strong diverging teeth , five 

 of which terminate so many dislinct ribs. The colour is yellow, shaggy in front, with 

 an aniher sloping forward and a subulate roslel. The poilenmasses 4, piane convex, 

 ia pairs at thc end of a broiid, Hat, thin caudicle, furnished on either side with a la- 

 teral tooth. (A singular monstrosily here occurred in the two posterior pollen- 

 masses, which had grown together into one by a narrow neck). A remarkable species, 

 the llower of which resembles a Lycaste , but iheir pollen apparatus and iip appen- 

 dage is of Warrea. Upon ihis point it may be useful to explain . ihat in Lycaste the 

 caudicle is subulate and the lip appendage a iruncate plate near the middle lobe of 

 the lip. while in VVarrea the caudicle is broad and Hat. and ihe lip appendage ribbed, 

 fringed and siationed at the very base of ihe lip.
