MACRADENIA.—Supra, vol. Sfol. 612. 



M. triandra ; foliis coriaceis lineari-oblongis acuminatis, racemo prostrr^-^ 

 laliello in medio trilamellato, clinandrio serrato antheris duabus sterilibus. 

 Pseudobulbi cylindracei paulo attenuati. Folia plurivenia. Race, 



foliis multo hreviorcs. Sepala et petala intus sanguinea herbaceo limbafc 



Labelli lamellcB rotundatcB, costcp formes^ antrorsiim crassiores. Anthe- 



steriles ovales, integrcB, sanguineo marginata:. 



The Macradenia lutescens of this work (folio G12) we liav 

 never seen ; but as it was described by Dr. Brown we liav 

 no difficulty in deciding, upon the evidence that the descrip- 

 tion affords, that it is specifically different from this. 



No notice is taken by Dr. Brown of the existence of an^ 

 lamellse in the middle of the lip, nor of the abortive antliers 

 which are always present ; besides which the clinandrium 

 here is regularly and strongly serrated, the leaves mucii 

 narrower, and the raceme pendulous or prostrate instead of 

 erect. 



A native of Surinam, whence it was broup;ht by Mr. 

 Lance. It flowered in the possession of tlie Horticultural 

 Society in May last. A strong damp stove heat is required 

 to keep it in health. 



* So named in allusion to the long caudicula of tiic pollen masses, fig. >>• froni 

 fiaKpoQ long, and ciap' a gland.
