 Litidl. Fol. I Oct. 14. 1852: A ^ingular litlle plant . wiih the habit of a Pleiiro- 

 thaliis; is neaily relaied to lonopsis, but is diirerenl in habit, and is essentially dis- 

 liiipuished by ils lip bcing nnt only parallel with the cohimn throughout its whole 

 lenpih, bni e.\cavalcd ai ihc base, and furnished there with two callosiiies like those 

 •of Spiranihes. Iis column is. moreover , long and narrow , and has two long meni- 

 branons reeurved ears hanging down fiom ihe apex. Tbe lip has no trace of ihe 

 auricles aiid calli of lonopsis , «or are the laieral sepals united into a pouch ; iher 

 are, however. siigbtly joined at the base, and gibbous there.

It gives me great plcasure to name this curious plant afier Edwin J. Quekett Esq. 

 F. L. S. an excellent Dotanical observer, and one of our most skillul anatomists. 

 I ara already indcbted lo thnl gentleman for some valuable facts concerning rapbides ; 

 a plant therefore in wliich ihese crysials form a conspicuous part of ihe structure 

 may not be inappropriiilely seiected to bear bis name. 



A very singular litlle plant, wiih ihe habit of Pleurolhallis, pollenmasscs of a Van- 

 deous 0., more allied to Rodriguezia, ihan to any ihing else . but quite different in 

 habii and essentially dislinguished by its cylindrical perianih , and Inbellum not only 

 parallel wiih the auriculate column throughout its whole length, but ezcavated at the 

 base and furnished there wiih 2 callosiiies like ihose of Spiranthes. Its leaves are 

 terete, siibulatp. about 3" long, and beaulifully moilled wilh light green , and purple, 

 5" high. Fabric of leaves below ihe epidermis! Flowers obound in raphides clus- 

 lered in cells larger than those, which surround them , and of a dilTerent colour, so 

 ihat the llower, when e.xaniined with low powers of ihe microscope looks as if it 

 were doited. I bave obscrved tbis in Liparis pendula (Bot. Reg. 1838. Misc. 128) and 

 in Bolbopbyllum fuscum (XXV, 1339. Misc. 5.) and it will probably be found a common 

 structure in the sepals and petals of 0. as we already know it is in iheir leaves and 

 siems. This caiidicula is excellently adapted to show the cellular nat. of that part 

 and to explain upon whnt plan it is formed in other cases. 



Lindl. Fol. I. c. : 'Wild in Drazil. Loddiges. (v. v. c). Leaves terete, subulaie. 

 about ihree incbes long, moiiled with light green , deep ^reen , and purple. Panicle 

 aboui tbree inches long, with a few capillary arms , and minute ovate acute inem- 

 liranous brncts. Flowers nearly sessile. cylindrical . two-tenths of an inch long, 

 whiie. Sepals linear acutc ; ihe laierals very sliglilly united and gibbous at ihe base. 

 Peials of ihe sanie lengih and form. Lip parallcl with the column , oblong , ralher 

 iiarrowcd lo ibe base, membranous, at the base iiself hollowed oul, downy on ihe 

 anterior edge , and furni.sbed at the foot of ihe column wiib a pair of callosities. 

 <^olumn linear, erect, wiih a pair of fnlcate obtuse ears curved downwards frora 

 eilbcr side of the stiguia , which is a uiere transverse cleft.
