Mexico. " Flowers pale purplish brown, somewhat spurred." A very 



doubtful plant, of which nothing more is known. 



Section 4. Muscos.e. Pedimculi filiformes, simplices aut bifidi, 

 rarius apice multifidi (folio plerumque longiores). Species 

 maxima pro parte minores, nonnuiiquam minimse. 



[)7 • P. ephemera ; folio oblongo emarginato basi paulo angustiore pedunculo 

 capillari paucilioro nunc gemino subsequali, ovario trialato, sepalis line- 

 aribus acuminatis carinatis lateralibus basi connatis, petalis nanis lan- 



ceolatis acuminatis, labello lineari recurvo. Biazil, Descourtilz. 



Flowers orange-yellow, nearly an inch long. Petals pink. Ohs. The 

 lateral sepals are described by M. Descourtilz as distinct, except at the 

 base ; they are represented in his drawing as being connate 

 '^ 98. P. linearis (Spec/clinia 1 linearis, L. no. 5.) ; caule ancipiti folio lineari- 

 oblongo subtri})lo longiore, spicis capillaribus bifloris : altero folio sub- 



eequali, altero duplo breviore. Mexico awiX Peru. Caules csepitosi^ 



2-3-unciales. Folia uncialia, apice sequalia, obtusa. 



99. P. parvifolia (Lindl. in Comp. to Bot. Mag. 2.) ; foho minimo ovali acuto 

 emarginato subsessih, pedunculo solitario folio longiore, sepalis oblongis 

 acutis inferiore emarginato majore, petalis nanis obovatis, labello oblongo 

 obtuso apice maculato. Brazil. 



100. P. muscoidea (Lindl. in Bot. Reg. 1838, misc. 105.) ; csespitosa, acau- 

 lis, folio ovali biconvexo, pedunculo setaceo bifloro, perianthio explanato 

 ringente, sepalis lineari-lanceolatis lateralibus basi ima connatis, petalis 

 multo minoribus conforraibus, labello oblongo-lineari obtuso canalicu- 



lato, polliniis 2 pyriformibus connatis. Brazil. The smallest 



Orchidaceous plant known. Leaves 2^ lines long. The peduncle is as 

 fine as a hair and about four lines long. Flowers purple. 



101. P. Lanceola (Spreng. Syst. 3. 731. Specklinia Lanceola, L. no. 2.); 

 caulibus brevissimis caespitosis, folio lanceolate subpetiolato, pedunculo 

 capillari bifloro longitudine folii, sepalis obtusis patentibus, petalis apice 

 subciliatis, labello oblongo obtuso concavo recurvo (purpureo margine 

 luteo). Jamaica. 



102. P. trijida ; cfespitosa, foliis lineari-lanceolatis marginatis apice triden- 

 tatis cauli sequalibus, pedimculis foliorum longitudine apice plurifloris, 

 sepalis obtusis antico bidentato concavo, petahs spatulatis apice rhom- 

 beis, labello oblongo retuso scabro a latere repando, columna petaloidea 



3-fida Brazil. The Organ Mountains furnished Mr. Miers with 



this small species, wdiose leaves and stems together are not more than 

 an inch and a half high. 



103. P. plantuyinea (Specklinia plantaginea, Poppig & Endl. 1 t. 89 A.) ; 

 csespitosa, caule brevissimo, foliis petiolatis spathulato-linearibus, pedun- 

 culis capillaribus unifloris, sepalis ovato-oblongis acutis ad medium 



connatis, labello lanceolato obtuso. Peru. Very near Lanceola, 



perhaps not distinct. The Specklinia graminea of Poppig and Endlicher 

 seems to be rather a Maxillaria. It cannot be even of the Pleurothalli- 

 dous division. 



104. P.pusilla (Dendrobium pusillum, IL B. K. 1. 357.) ; caule monophyllo, 

 folio elliptico acutiusculo, pedunculis solitariis aut ternis uni vel bifloris,
