extus trinerviis, petalis membranaceis subtruncatis, labello ovate 



acute. 

 Brazil (Miers). 



Flewers very small, pale straw-celour. Leaves about two inches 

 long. Near S. spathulata. 



14. Stelis Serra ; felio oblengo marginato apiculate basi angustato, 

 spicis subgeminis erectis strictis duple longioribus, bracteis disti- 

 chis evatis acutis internediis longieribus, sepalis rotundatis, petalis 

 retusis membranaceis, labello membranaceo trilebo. 



Peru, in prov. Chachapoyas (Mathews). 



Whole plant abeut three inches high . Flowers a little longer than 

 the bracts, very small. 



15. Stelis /ej?M05a ; felio oblonge acute tridentato marginato in pe- 

 tiolum angustato, racemis subgeminis filiformibus flexuesis multi- 

 fleris 2 — 3plo longieribus, bracteis minimis ovatis acutis pedicellis 

 brevieribus. 



Peru (Mathews, no. 1910). 



Leaves about three-quarters of an inch long. Racemes drooping, 

 zigzag ; bracts very minute at the angles of the axis. 



16. PLEUReTHALLis ttureu ; folio sessili oblengo horizontali obtusis- 

 simo, raceme stricto selitario 4plo longiore, sepalis lineari-lanceo- 

 latis acuminatis intus glanduloso-scabris lateralibus basi tantum 

 connatis, petalis eblengis obtusis carinatis triple brevieribus, labelle 

 ebovato apice rotundate lineis duabus flexuosis elevatis, clinandrio 

 lacero. 



Caraccas (Linden, no. 634). 



The flowers are bright yellow, probably with a little purple streak- 

 ing. The raceme is nine inches long. The sepals are seven lines long. 

 The habit is that of P. racemiflora, to which and P. pulchella it is 

 nearly related. 



17. Pleurothallis Lindenii; caule nude felio oblongo-lanceolato 

 acuminate sessili duplo longiore, raceme filiformi selitario pendule 

 folio breviore, sepalis subdiaphanis acuminatis glabris lateralibus 

 in cochlear connatis, petalis sequilongis acuminatis coriaceis, labello 

 nane cordate acute. 



Caraccas (Linden, no. 630). 



Flewers large, apparently violet, about four en the lax solitary 

 raceme. Perhaps this with P. Mathewsii and some ether leng- 

 petaled species may form a good section in this difficult genus. 



18. Epidendrum (^Encyclium) Lindenii; foliis binis eblengis obtusis 

 racemi peduncule sequalibus, raceme laxo, fleribus carnosis, sepalis 

 lanceolatis ebtusiusculis, petalis basi angustatis, labelli subrotundi 

 3-lobi laciniis lateralibus rotundatis, intermedia subcuneata, callo 

 disci tementoso, clinandrio obtuse 3-dentate, cardinis appendice 

 bidentata. 



Caraccas (Linden, no. 624). 



Very near Epidendrum pterocarpum, but the flewers are larger, and 

 apparently deep rose-colour.
