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, 1-13 foot high, and large purple- 
fringed flowers. It is one of the handsomest of the genus. 
76. ONCIDIUM unicorne; pseudobulbis ovalibus compressis diphyllis, foliis 
oblongo-linearibus recurvis, racemo composito ramis divaricatis rectiusculis, 
sepalis lateralibus in unum concavum emarginatum connatis, petalis obovatis 
undulatis, labelli lobis lateralibus nanis intermedioque emarginato rotundatis, 
disco basi transversé elevato anticé cornu ascendente compresso subfalcato 
acuto, alis columne 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 sphericis, scapo paniculato, 
sepalis petalisque obovato-oblongis, labelli liberi trilobi cucullati lobo medio 
crispo acuminato, disco elevato calloso sulcato pubescente. 
The first knowledge 1 had of this plant was from M. 
Alphonse DeCandolle, 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 | 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
