 mseformes. Flores 7 lin. longi. Sepala oblonga apiculata apice 

 recurva, verosimiliter viridia. Labellum apice rotundatum, cris-

 Peru, Matthews in herb. Hooker. 



This very curious genus is probably related to Macradenia, but its 

 habit and structure are in all respects very peculiar. The gland re- 

 sembles a long bristle or cobbler's awl, and projects beyond the 

 column, extending as far as its long falcate arms. The anther, 

 which is globose where the pollen lies, is furnished in front with a 

 broad circular crest. 



6. Bolbophyllum Napelli ; pseudobulbis conicis, folio oblongo ob- 

 tuso, scapo 1-bifloro folii longitudine apice ipso sub flore bibrac- 

 teato, bracteis setaceis insequalibus, sepalis lateralibus dorsalibus 

 galeatis ovatis acutis, petalis conformibus paulo minoribus, labello 

 lineari obtuso unguiculato, columna basi utrinque in dentem acu- 

 minatum producta. 



Brazil, Descourtilz, Miers. 



A very singular species with a solitary flower, white with violet 

 stripes, and about half an inch long. In form it much resembles the 

 flower of Aconitum Napellus, which suggested to M. Descourtilz its 

 specific name. The lip is white with green veins. 



7. Bolbophyllum tripetalum ; pseudobulbo tetragono, folio oblongo 

 acuto racemo breviore, scapo 6 — 7-floro flexuoso erecto, bracteis 

 ovatis scariosis ovario longioribus, sepalis linearibus acutis patulis, 

 petalis minimis squamseformibus, labello ciliato unguiculato apice 

 oblongo obtuso basi ima utrinque auriculato, columna 4-dentata. 



Brazil, Descourtilz. 



A good figure of this exists among M. Descourtilz's drawings. It 

 is related to B. saltatorium, like which its lip appears to be delicately 

 and elastically articulated with column. The sepals are pale yellow, 

 three-quarters of an inch long. The lip is bright yellow with crim- 

 son spots. It is stated by its discoverer to be scentless and to cover 

 whole trunks of trees. 



8. Bolbophyllum gladiatum ; pseudobulbo ovato tetragono, folio 

 oblongo carinato spica longe pedunculata multo breviori, spica 

 secunda multiflora, rachi subclavata, sepalis linearibus lateralibus 

 connatis, petalis obovatis ciliatis limbatis, labello unguiculato cor- 

 dato in processum angustum gladiatum villosum elongato, columna 

 4-dentata. 



Brazil, Descourtilz. 



A most singular plant, the appearance of whose flowers is thus 

 described by M. Descourtilz : — " The upper sepal is very long, very 

 narrow, channeled at its base, acute at the point, lemon-coloured, as 

 well as the two lateral, which are joined by their edges into one, 

 two-toothed at the point. From the position constantly assumed by 

 the flower, these three sepals are placed right and left of the axis.
