oblongo denso, sepalis iineari-oblongis aequalibus reflexis 

 basibus lateralium paulo obliquis, petalis ovatis erectis 

 supra columnam conniventibus, labello replicato retrorsum 

 arcuato cuneato trilobo : lobis lateralibus deflexis venosis 



intermedio carnosiose cuspidato subtrilobo. Central 



America. Flowers deep purple, on a close erect raceme. 



2. M. lineatum (Bateman in Bot. Reg. 1841, misc. no. 107. 

 1842, t. 43.) ; racemo elongato multifloro, sepalis petalis- 

 que oblongo-linearibus abrupte acutis margine reflexis, 

 labello lineari incurvo carnoso sparsim piloso versus basin 

 utrinque dente nunc brevi nunc elongato aucto, columnar 



dorso et margine pubescente. Guatemala. The 



flowers are deliciously fragrant; when they first appear 

 they are dull olive green ; they afterwards acquire a bright 

 warm yellow tint, and the markings upon them increase 

 in intensity till they have become orange-red. 



3. M. aromaticum (Lindl. in Bot. Reg. 1841, misc. 162.); 

 racemo brevi erecto, sepalis petalisque subrotundo-ovatis 

 acutis secundis concavis, labello anguste cuneato convexo 



lacinia intermedia triangulari acuminata cucullata. 



Mexico. This has flowers with a pale pinkish ground 



sown thickly with dull wine-red specks, and a powerful 

 odour like that of aromatic vinegar. It differs from M. 

 pardinum in the small size of its flowers, and the very dis- 

 similar form of the lip and floral envelopes. 



4. M. pardinum (Bateman Orch. Mexic. t. 14. Hooker Bot. 



Mag. t. 3900. Cyclosia maculata, Klotzsch in Gartenzeit.

5. M. luxatum (Lindl. in Bot. Reg. 1842, misc. 66. 1843, t. 

 33.); foliis longissimis angustis subtus glaucis racemo ob-
