109. ANGR^CUM aTmeniacum ; caulescens, foliis distichls canaliculatis 

 apice obliqu^ et acut^ bidentatis, spicis latcralibus horizontalibus secundis, 

 scpalis ovatis, pctalis lincaribus, labclli 3-lobi laciniis latcralibus acumiiiatis 

 intermedia triangularl longioribus, calcare pendulo clavato basi compresso 

 calyce duplo longiore. 



This very singular plant is a native of Sierra Leone, 

 whence it has been obtained by Messrs. Loddiges. Its 

 flowers are of a uniform apricot-colour, small, secund, and 

 closely arranged in a horizontal lateral spike. The habit is 

 that of a Saccolabium. It is very distinct from all that have 

 before been seen, but has some affinity with Angraecum 

 mystacinum. The spur is twice as long as the calyx, com- 

 pressed at the base, and then inflated a little so as to appear 

 clavate. 



1 1 0. MALACHADENIA (Vaude^e). 



Flos resupinatus. Sepala lateralia connata, apice rcflexa libera, galcam for- 

 mantia ; dorsale cordatum acuminatum. Petala minima, squamaiformia, 

 rotundata. Labellum carnosum, margine revolutum, basi mucronatum, cum 

 pede elongato columnae sepalis lateralibus galeatis adnatae articulatum. 

 Columna antice bicirrhosa, basi longe producta, stigmatc lineari oblongo. 

 Anthera 2-locularis, decidua. Pollinia 2, ceracea, sessilia, glandulii molli, 



cubica, nuda. Herba repens, pseudobulbis monophyllis, scapo radical!, 



floribus carnosis galeatis. 



MALACHENIA clavata. 



Rhizoma repens. Pseudobulbi subglobosi, monophylli. Folia anguste 

 ovalia, carnosa. Scapus radicalis, foliis ter longior, erectus, teres, apice cla- 

 vatus, subbiflorus ; axi spicae articulata : internodiis clavatis. Spica termi- 

 nalis, pauciflora. Bractese membranacea;, ferrugineae, reflcxae. Ovarium 

 brevissimum. Flores obscure virides purpureo maculati. Sepala lateralia 

 acuminata, apice revoluta, basi obscure semisagittata ; supremum subcorda- 

 tum : sinu lato inter sepala. Petala squamiformia, rotundata, obsoleta. 

 Glandula poUiniorum mollis, subcubica, cinnamomea, cui pollinia leviter 

 annectantur. 



This very singular plant was given to Mr. Bateman by 

 Mr. Wm. Hooper of Lambeth, who received it from Rio in 

 1836. It is a remarkable genus, resembling Megaclinium 

 in some respects, but belonging in reality to Yandeae, among 

 which it is marked by the nearly total absence of petals, 

 the cirrhate column, and the soft fleshy cinnamon-coloured 

 gland, to which a pair of reniform pollen-masses are slightly 

 attached. In this division of Orchidacca3 it is uncertain 

 where it must stand ; probably other genera still undis- 

 covered will connect it with the system better than can at 

 present be done.
