Orchideous Plants of Chile. 49 



long, with distant flowers, enwrapped in inflated membranous "bracteae. 

 Flowers small for the genus, galeate. Upper sepal falcate, inflexed, 

 membranous, three-veined ; the veins being strongly marked and con- 

 nected by distinct transverse venulae ; ifiner lateral sepals membranous, 

 obovate-rhomboid, unequal-sided, veiny, at the base obliquely attached 

 to the columna, with the veins in a high degree varicose ; lower sepals 

 at first erect, then divaricating, oblong, with broad, dilated, fleshy apices. 

 Labellum ascending, with a long incurved unguis, which has a double 

 tubercle at the base ; the lateral lobes cucuUate, each with two crests 

 on the inside, of which the innermost consists of a single lamella, and 

 the exterior of several glandular excrescences ; the middle lobe rounded, 

 fleshy, naked ; crest nearly obsolete, represented by three obscure 

 raised lines near the base. Columna erect, clavate, with a membranous 

 margin, having a large callus at the base. 



The resemblance of this species to a gigantic Pterostylis rufa 



has been already noticed. 



5. C. lamellata; foliis erectis acutis abbreviatis, bracteis 

 flore longioribus, sepalo superiore lanceolato venoso ; inferio- 

 ribus porrectis apice dilatatis spatulatis carnosis, labello 

 oblongo unguiculato membranaceo crenato, crista lamellata.

 About a foot high. Leaves veiy short, erect, acute. Scape leafy at 

 base, clothed with numerous somewhat inflated squamae. Spike nod- 

 ding, very compact, occasionally branched. Flowers connivent, longer 

 than the membranous acuminate bracteae. Sepals strongly marked 

 with distinct, nearly s mple veins ; the upper lanceolate, compressed, 

 tliree-nerved, reticulated ; innei' lateral membranous, oblong, with 

 slender simple veins ; lower narrow, parallel with the lip, at the apex 

 fleshy and deltoid. Labellum oblong, unguiculate, entirely membra- 

 nous, cucullate, wavy, crenate, obsoletely three-lobed ; the veins all 

 crested with compressed lamellar inten*upted processes, which dwindle 

 towards the margins into little nodosities. Columna with a membra- 

 nous margin, erect, shorter than the labellum. 

 This has an almost aphyllous habit, and is abundantly dis- 

 tinct from all the other species in its labellum, being wholly 

 membranous, and crested with lamellar appendages. 



6. C multiflora ; foliis oblongis scapo longe brevioribus, 

 sepalis inferioribus lanceolatis patentibus apice carnosis dila- 

 tatis hinc membranaceis, labello oblongo membranaceo ungui- 

 culato : crista rar^ glandulos^ ; lobis lateralibus abbreviatis : 

 intermedio elongato obtuso crispo.
