extus trinerviis, petalis membranaceis subtruncatis, labcllo ovate 



acute. 

 Brazil (Miers). 



Flowers very small, pale straw-colour. Leaves about two inches 

 long. Near S. spathulata. 



14. Stelis Serra ; folio oblongo raarginato apiculato basi angustato, 

 spicis subgeminis erectis strictis duplo longioribus, bracteis disti- 

 chis ovatis acutis iuternodiis longioribus, sepalis rotundatis, petalis 

 retusis membranaceis, labello membranaceo trilobo. 



Peru, in prov. Chachapoyas (Mathews). 



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

 the bracts, verj' small. 



15. Stelis Jiexuosa ; folio oblongo acute tridentato marginato in pe- 

 tiolum angustato, racemis subgeminis iiliformibus flexuosis multi- 

 floris 2 — 3plo longioribus, bracteis minimis ovatis acutis pedicellis 

 brevioribus. 



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. Pleurothallis aurea ; folio sessili oblongo horizontal! obtusis- 

 simo, racemo stricto solitario 4plo longiore, sepalis lineari-lanceo- 

 latis acuminatis intus glanduloso-scabris lateralibus basi tantum 

 connatis, petalis oblongis obtusis carinatis triplo brevioribus, labello 

 obovato apice rotundato lineis duabus flexuosis elevatis, clinandrio 

 lacero. 



Caraccas (Linden, no. G34). 



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 nudo folio oblongo-lanceolato 

 acuminate sessili duplo longiore, racemo filiformi solitario pendulo 

 folio breviore, sepalis subdiaphanis acuminatis glabris lateralibus 

 in cochlear connatis, petalis sequilongis acuminatis coriaceis, labello 

 nano cordate acute. 



Caraccas (Linden, no. 630). 



Flowers large, apparently violet, about four on the lax solitary 

 raceme. Perhaps this with P. Mutheivsii and some other long- 

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



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

 racemi pedunculo sequalibus, racemo laxe, floribus carnosis, sepalis 

 lanceolatis ebtusiusculis, petalis basi angustatis, labelli subrotundi 

 3-lobi laciniis lateralibus rotundatis, intermedia subcuneata, callo 

 disci tomentoso, clinandrio obtuse 3-dentato, cardinis appendice 

 bidentata. 



Caraccas (Linden, no. 6-J4). 



Very near Epidendrum pferocarpuni, but the flowers are larger, and 

 apparently deep rose-colour.
