1 84 Prof. Lindley on new Orchidaceous Plants, 



XXIX. — A Century of new Genera and Species of Orchi- 

 daceous Plants. Characterized by Professor Lindley. 



Decade 1. 



1 . Eulophia filicaulis ; foliis , scapo gracillimo paniculato, 



bracteolis pedicellis multo brevioribus, sepalis petalisque lineari- 

 bus obtusis, labello oblongo apice trilobo basi in cornu brevi pro- 

 ducto, laciniis lateralibus brevibus intermedia oblonga concava 

 crispa intus leevi venis quibusdam paulo elevatis, anthera bicristata. 



Mexico, Karwinski in herb. reg. Monac. 



A very slender graceful plant, with the flowering stem 1| foot 

 high. 



2. Eulophia dilatata; foliis , scapo stricto simplici, bracteis 



acuminatissimis ovario brevioribus, sepalis lanceolatis acutis, peta- 

 lis paulo obtusioribus et latioribus, labello basi mutico biauricu- 

 lato sursum dilatato obtuso : venis 5 basin versus lamellatis. 



Mexico, Karwinski in herb. reg. Monac. 



Flowering scape more than 2 feet high. Sepals about three-quar- 

 ters of an inch long. 



3. Govenia pauciflora; foliis binis oblongis acutis scapo paulo bre- 

 vioribus, racemo 7 — 8-floro, bracteis lanceolatis membranaceis pe- 

 dicellis brevioribus, sepalis oblongis acutis, petalis labelloque intus 

 lsevi ovato-lanceolatis, antherse mucrone recurvo. 



Mexico, near Jesus del Oro, Karwinski in herb. reg. Monac. 



A very remarkable species, with short oblong acute leaves, and a 

 few-flowered scape not much longer than themselves. The whole 

 plant is little more than a foot high. 



4. Isochilus cernuum ; caulibus csespitosis filiformibus erectis, foliis 

 teretibus obtusissimis, spatha terminali bivalvi, pedunculis elon- 

 gatis, floribus cernuis, sepalis ovatis petalisque linearibus obtusis, 

 labello concavo subtrilobo columnar adnato apice carnoso acuto 

 utrinque rotundato membranaceo, linea elevata in medio. 



Mexico, Karwinski. 



The habit of this plant is that of Isochilus globosum, but its stems 

 are nearly 6 inches high and stout in proportion, and the flowers are 

 half an inch long : they seem to be yellow. 



5. Sutrina (Nov. gen. Vandearum). Perianthium cylindraceum, 

 clausum. Sepala coriacea, lateralia fere ad apicem usque connata, 

 basi subsaccata. Petala membranacea, conformia. Labellum li- 

 berum, unguiculatum, supra basin medio elevatum, oblongum, con- 

 cavum, indivisum. Columna basi teres, sursum dilatata, apice 

 utrinque alis falcatis instructa; clinandrio antice bidentato. An- 

 thera membranacea, semibilocularis, antice membrana lata circu- 

 lari cristata. Pollinia 2, pyriformia, solida, caudiculse lineari in 

 glandulam longissimam setaceam incumbenti affixa. — Herba gla- 

 bra epiphyte, pseudobulbosa, foliis solitariis coriaceis, spica multi- 

 ilora pendula.
