46. HEXADESMIA fasciculata. 



Adolphe Brongniart in Ann. Sc. xvii. j9. 44. 



Under this name has been just described by M. A. Brong- 

 niart, a Mexican Orchidaceous plant, found in that country by 

 Linden, and which has flowered in the Garden of Plants. 

 There is no doubt about its being the same as Mr. Bateman's 

 unpublished genus Hexopia, whose name must therefore be 

 cancelled. The following is the description of the plant in 

 the Annales des Sciences. 



HEXADESMIA. Sepala subconniventia, supremo oblongo-lanceolato, late- 

 ralibus triangularibus infra cum basi columnse in pseudo-calcare unitis. 

 Petala sepalis subaequalia oblonga. Labellum cum basi producta columns 

 articulatum, subintegrum, plicatum. Columna petalis brevior, semiteres, 

 apice clavata, clinandrio auriculis lateralibus et dente postica uncinata 

 marginato, basi foveola nectarifera excavata. Anthera operculae formis, 

 denti marginis clinandrii affixa, carnosa, sexlocularis. Pollinia 6 aequalia, 

 4-posticis caudiculis longioribus replicatis, 2 anterioribus caudiculis bre- 

 vissimis, tria ad utrumque lobum antherae pcrtinentia et interse cau- 

 diculis unita, facillim^ glutine apicis caudiculorum in fasciculo unico 

 connexis. 



Herba mexicana ab indefesso viatori Linden Musseo Parisiensi allata, habitu 

 Dendrobia qusedam asiatica et forma floris Apora praesertim referens, 

 sed polliniorum structura cum Epidendreis quadrans eorumque numero 

 ab aliis hujusce familiae generibus, excepto Hexameria R. Br. k tribu 

 Malaxidearum, distincta. 



H.fa8ciculata. Caules e rhizomate nascentes, erecti, basi graciles squamis 

 vestiti, superius incrassato-subspathulati bulbosi ; pseudobulbis stipitatis 

 compressis elliptico-lanceolatis apice, diphyllis. Foliis oblongis 5-6 pol- 

 licaribus, pollice lata, coriacea, plana, apice emarginata. Flores ter- 

 minales 2-4 fasciculati subsessiles, e spatha communi brevi exeuntes, 

 pedicellis ovariisque gracilibus incurvis, squamis obtectis. 



48. CATASETUM globifl6rum. 



Hooker in Bot. Mag. t. 3942. 



C. globiflorum ; spica elongate multiflora, perianthio globoso, sepalis petalis- 

 que subconformibus ovatis acutis concavis arctissime imbricatis, labello 

 hemispheerico-globoso, ore contraeto oblongo inferne dilatatp basi co- 

 lumnse longitudine denticulato, columnse brevis setis rectiusculis. 

 Hooker 9 /. c. 



A Brazilian plant, very much like C. Hookeri, and perhaps 

 a variety of it. The sepals and petals are olive-brown, and 

 closely applied to a glaucous globular labellum, the greater 

 part of which is uncovered. It is stated in the Botanical 

 Magazine to have flowered in the Glasnevin Botanic Garden.
