M. pseudobulbis diphyllis ovalibus ancipilibus, foliis ligulatis obtusis, 

 scapo ancipiti arcle vaginalo mullo brevioiibus, racemo disticho flexuoso, 

 niultifloro, bracteis carinatis convolulis acuminatis glumaccis ovario lon-

M. stellata Lindl. Sert. t, 48. 



Cyrtochilum steUatum Lindl. Scrt. t. 7. 



Cyrtochihnn flavescens Lindl. in Bot. Reg. t. 1627. 

 Flowers pale yellow wiih no spots. Lip white with yellow sireaks. Wings of 

 tbe column yellow streaked wiih crimson, Bracis rose-coloured. I believe. that my 

 M. flavescens and stellata are ihe same species in dilTcreni staies . M. stellata being 

 a very large vigorous specimen and iM. flavescens a small starved onc. The so- 

 called Mexican habitai of thc latter is certainly a misrcpresentation of some nursery- 

 man, It is singular, that the yarge form represented by Descourtilz in liis drawings 

 in the possession of M. Dclessert, and on wbich M. siellaia was founded , bas no- 

 vvhere occurred in the many collections of wild Brazilian plants, that have been sub- 

 miited to me. Evcn Mr. Micrs has in bis herbarium nothing beyond a specimen from 

 ihe Garden at Rio Janeiro.
