41. P. caulescens (Lindl. in Hooker's Bot. Misc. 2.); caulibus ascendentibus 

 foliosis gracillimis, fohis membranaceis patentibus vaginantibus Hneari- 

 lanceolatis vix costatis, racemis 2-3 terminalibus erectis subsecundis cau-

 lateralibus subconnatis, petalis ovatis acutis duplo brevioribus, labello 



postico unguiculato ovato obtuso obsolete trilobo complicate. Peru. 



This is another of the species which bear many leaves on a steni 



instead of one ; they do not however appear to possess any other cha- 

 racter in common.

viore, bracteis membranaceis ochreatis, floribus pendulis, sepalis acumi- 

 natis lateralibus apice tantum liberis, petalis minimis oblongis acutis, 

 labello lineari canaliculato acuto margiuibus incrassatis, columna basi 



pubescente. Brazil. Flowers cinnamon-coloured. The leaves are 



veiy like those of Leptotes bicolor. 



43. P. rupestris (Lindl. in Bot. Reg. sub t. 1757.); folio tereti mucronato 

 antice sulcato racemo stricto rigido paulo breviore, bracteis parvis rigidis 

 concavis, sepalis acutis lateralibus semiconnatis, petalis lanceolatis cili- 

 atis, labello subtrilobo membranaceo obtuso appendice magno carnoso 



bifurco : cruribus parallelis porrectis acutis. Brazil. Scapus ru- 



benti-virens. Sepala purpurascentia. Petala purpurea. 



Section 2. Effusjd. Spicse v. racemi folio multo breviores. 

 * Lceves ; nempe, floribus omnino pube orbatis. 



44. P. macrophylla (L. no. 11. Y. floribunda, Popp. & Endl. t. 84.); caule 

 semitereti folium oblongo-lanceolatum petiolatum coriaceum erectum 

 duplo excedente, racemis fasciculatis numerosissimis patuhs folio triplo 

 brevioribus spatha saccata basi inclusis, sepalis ovato-oblongis inferiori- 



bus ad basin liberis, labello subrotundo basi apiceque acuminato. 



Peru. A specimen in the herbarium of Willdenow identifies Poppig's 



P. floribunda and the macrophylla of Humboldt and Kunth. 



4.T. P. deciu-rens (Poppig & Endl. t. 83.) ; caule anguloso folium subrotun- 

 dum utrinque acutum ad medium cordatum lobis adnatis decurrens 

 triplo excedente, spicis in sinu medii folii paucis abbreviatis oliganthis, 

 sepahs sequilongis iuferiore ex duobus ad apicem connatis consistente 



latiore bimucronato. Peru. A large species looking like P. 



Mathewsii. 



46. P. secunda (Poppig & Endl. t. 85.); caule tereti folium oblongum acu- 

 minatum basi acutum triplo excedente, racemis folio brevioribus capilla-
