 convexis subyequalibus lateralibus omnino connatis, petalis brevioribus 

 lineari-sLibulatis serrulatis, labello unguiculato oblongo eagittato piloso 



venii intermedia, apice varicosa. Peru. The habit of this plant is 



the same as of P. succosa, but the leaves are more horizontal. 



91. V. cor data (L. no. 4.) ; caule tereti sulcato folio subrotundo coriaceo 

 horizontali alte cordato acurainato multo lougiore, floribus fasciculatis e 

 spatha brevi coriacea subexsertis. Peru. One of the largest spe- 

 cies, with stems a foot high, and almost destitute of sheaths.

 ovato-lanceolatum acuminatum cordatum undulatum membranaceuni 

 horizontale triplo cxcedcnte, floribus in sinu folii fasciculatis paucis pe- 

 dunculos spatha truncatu membranacea inclusos pcquantibus, sepalis 

 oblongo-lanceolatis acuminatis inferioribus ad apicem usque connatis, 



labello oblongo apice obtuso bidentato erecto piano. l^eru. This 



is very near P. cordata, if not the same. Poppig and Endlicher state 

 that it differs in the leaves being coriaceous and undulated.

 vaginis caulis 2-3 ventricosis, folio oblongo piano 7-9-venio, flore soli-

 ciam longus, angustus, falcatus. Sepala anteriora basi gibbosa, oblongo- 

 linearia. Petala nana, vix 2 lineas longa, ovata, 3-cuspidata, obliqua, 

 ssepius vena altera excurrente, altera in dimidio majore petali abbreviata.

 tum ; uugue lineari, 3-venio axi cristato, lamina sagittata apicibus pos- 

 ticis obtusis. Columna petaloideo-alata, apice tridentata.

95. P. sica7'ia (Lindl. in Bot. Reg. 1841. misc. 187.) ; folio oblongo angusto 

 piano in caulem triplo longiorem triquetrum canaliculatum deorsum 

 attenuatam angustato, pedunculis brevibus 2-3-floris cernuis aggregatis, 

 sepalis lincari-lanceolatis patulis chartaccis lateralibus ad apicem usque 

 cohagrentibus sed facile separabilibus, petalis ovalibus acutissimis ser- 

 ratis, labello lanceolate acutissimo bilamellato utrinque unidentato, 



clinandrio serrato. Trinidad. This species is remarkable, in its 



stem being exactly like a bayonet blade with the point downwards. It 

 grows nearly a foot high. The flowers are greenish yellow with pale 

 purple stripes along the petals, and none at all on the labellum.
