Obs. Nescio , cur ill. Lindley (Folia IX.) amiciss. Seemnnii pro auciore scribat, 

 cum et in Botany of Herald, et in Xeniis t. I. 173 et tab. 70 nomen meum distincie 

 legere potuisset : forsan nebulae Londinenses irapedimento fuerunt, 



Cl. Lindley dicit: „ but ibe lip in dilferent; by no means , however , slipper 



shaped as it appeared to Rchb." 



Haec scribit, dum tres lineas superius habet : „labello concavo carnoso apice in- 

 flexo". Calcei Anglorum nonne sunt convexi ?

Obs. III. Liiidley (Folia VIIL) aliter seiiliens planiam descripiara pro adversa specie 

 habel exciamans : „1 am qiiiie at a loss lo uiiderstand upon wlint ground this remar- 

 kable plant has been referred to the IM. lauiifolia of II. li. K., whicli in expressly 

 declired to be rclated to P. ruscifolia, a well kiiown species anioiig .' ggregatae. I have 

 never seen aiiy thing to which Uclib*s description al all ap|ilies. He says the stera of 

 his planl is siout and aboui 1' bigb ; and thc leaf 6" X 2— 3*'; tlial it has an 

 acule keeled spatlia ; and thnt tlie llowcrs are as inrge as in Sclilimia jasraiiiodora 

 tbat is to say a full iiich long by 'A inch acro&s the lube. Had this PI. laurifolia 

 been described by a less experienced orchidologist than Professor Rchb., il meight 

 bave been reasonably doubted , wheiher the planl is a Pleurothallis at all." 

 Ad baec Rchb. fll. haec respondet: 

 i) Planla oraui no non a Wageiiero lecta , unde descriptio inparenthesi daia.
