and the flowers themselves are nearly of the same length when closed. 

 The species is near L. rubescens and acuminata, but the flowers are 

 much larger, the flower-stalks much longer in proportion, and the label- 

 lum quite round at the point and flat. The pseudobulbs are not at all 

 tetragonous, but are compressed, with only a slight line in the room of 

 the intermediate angle. 



9. L. rubescens (Lindl. in Bot. Reg. 1S40. misc. 25. 1841. t. 41.); pseudo- 



bulbis subrotundis compressis utrinque angulo elevato, foliis oblongis 

 obtusis scapo tereti vaginato brevioribus, racemo multifloro, bracteis 

 ovario plus duplo brevioribus, sepalis linearibus, petalis lanceolatis sub- 

 undulatis, labello confornai auriculato medio pubescente : lineis duabus 



elevatis. Mexico. Flowers white, tinged with pink, the petals and 



lip wavy, the latter with a yellow disk, and a deep purple spot near 

 the base. 



10. L. acuminata (Lindl. in Bot. Reg. 1841. t. 24.); pseudobnlbis ovatis 



compressis rugosis, foliis solitariis emargiuatis scapo erecto brevioribus, 

 floribus corymbosis, bracteis linearibus acuminatis ovario duplo brevio- 

 ribus, sepalis linearibus petalisque lanceolatis uudulatis acuminatis, la- 

 belli lobis lateralibus rotaudatis intermedio lanceolato undulato acumi- 

 nate. Guatemala, where it is called Flor de Jesus. Resembles 



the L. rubescens ; but the flowers are larger, the lip less yellow, and the 

 purple spot at its base less intense. 



11. L. albida (Lindl. in Bot. Reg. 1839. misc. 4. t. .54.) pseudobnlbis ovali- 

 bus diphyllis, foliis linearibus acutis spica multiflora, 4-plo brevioribus, 

 sepalis oblongo-lanceolatis acutis vel snbacuminatis petalisque latioribus 

 acutis, omnibus apicibus reflexis fortiter mucronulatis; labelli alte trilobi 

 tricostati lobis lateralibus erectis rotundatis intermedio duplo majore 



subrotundo obscure apiculato reflexo. Mexico. Flowers white, 



tinged with pink, very sweet-scented, like Primroses. Petals and lip 

 reflexed. Mr. Barker has communicated a curious monster of this plant, 

 with the dorsal sepal united to the back of the column by means of a 

 thin plate resembling a small knife-blade. What is very singular every 

 flower of the specimen was in the same state. 



Sect. II. Parviflor/E. Petals the same size as the sepals. 



Brazilian. 



12. L. Jlava (Lindl. in Bot. Reg. 1839. misc. 143. 1842. t. 62. L. cau- 

 lescens, Lindl. in Bot. Reg. 1841. sub, t. 1.) Bi-azil. 



13. L. cinnabarina (Bateman in Sertum Orchidaceum, t. 28.); pseudobulbis 



cylindraceo-ampullaceis elongatis, foliis binis basi discretis oblongis sub- 

 recurvis et undulatis, scapo tenui ascendente foliis multo longiore 4-5- 

 floro, sepalis petalisque oblongo-linearibus obtusis eequalibus, labelli 

 oblongi convoluti recurvi lobis lateralibus acutis intermedio ovaH cris- 

 pato, lineis 3 elevatis in axin. Brazil. Flowers rich orange- 

 colour. 



14. L. rupestris ; pseudobulbo elongato monophyllo, folio oblongo erecto ca- 



naliculato scapo racemoso multifloro breviore, sepalis petalisque oblongis 

 acutis, labelli circularis lobo intermedio obtuso margine crispo disco 



piano lateralibus obtusis, lineis 2 elevatis rectis. Brazil. Found 



by Professor Gardner in elevated rocky tracts in the Diamond District. 

 " Flowers violet." Very near L. flava.
