much longer than the stipules, as well as much shorter than 

 the phyllodia. 



75. THYSANOTUS isantherus. R. Brown Prodr. 139. 



This fine species has lately flowered at Vienna with Baron 

 Hugel. It is a greenhouse herbaceous plant, with very short 

 leaves, rushy stems, 1-1 J foot high, and large purple- 

 fringed flowers. It is one of the handsomest of the genus. 



76. ONCIDIUM unicorne ; pseudobulbis ovalibus compressis diphyllls, foliis 



oblongo-linearibus recurvis, racemo composito ramis divaricatis rectiusculis, 

 sepalis lateralibus in unum concavum emarginatura connatis, petalis obovatis 

 undulatis, labelli lobis lateralibus nanis intermedioque einarginato rotundatis, 

 disco basi transverse elevato antic^ cornu ascendente compresso subfalcato 

 acuto, alis columna; angustis obsoletis. 



This is a pretty little species, with a compound straggling 

 raceme of pale yellow flowers. The singular horn on the lip, 

 to which it owes its name of the " Unicorn," at once dis- 

 tinguishes it from all species previously described. Messrs. 

 Rollissons imported it from Rio, and flowered it three weeks 

 since. 



77. EPIDENDRUM Candollei; pseudobulbis spbjEricis, scapo paniculato, 



sepalis petalisque obovato-oblongis, labelli liberi trilobi cucuUati lobo medio 

 crispo acuminato, disco elevato calloso sulcato pubescente. 



The first knowledge I had of this plant was from M. 

 Alphonse DeCandoUe, who shewed me a drawing of a very 

 imperfect specimen that had flowered at Geneva, and which 

 I took for a variety of Ep. asperum. Subsequently the same 

 species has flowered with Messrs. Loddiges, and I find that 

 it is distinct. The flowers are dull brown, with a dull yellow 

 lip, striped with the same colour. It is a Mexican plant. 



78. GLAUCIUM rubrum. DC. prodr. 1. 122. 



This plant, a native of Asia Minor, and of Rhodes, is now 

 a common biennial, under the name of G. elegans. It has 

 handsome poppy-red flowers, not so large, but much richer 

 than those of the common horned poppies. 



79. ERYSIMUM Perofskianum. Fischer & Meyer Ind. iv. p. 36. 



This very pretty hardy annual plant, with bright orange 

 sweet-scented flowers, has been raised in the garden of the 

 Horticultural Society, from seeds collected in the north of
