flowers are usually lemon-coloured, with a large num- 
ber of lilac spots on the sepals, a smaller number on 
the petals, a deep yellow eye, and two, or occasionally 
four, large dark brown spots on the side of the lower part 
of the lip, which is very much lengthened out as if ungui- 
culate ; by the latter circumstance it is chiefly known 
from S. Wardii Many supposed varieties occur in the 
gardens, varying in colour, and in the spotting of the lip. 
There is one, called Barkeriana , which is more remark- 
able than the others ; it looks like S. insignis with the 
lip of S. oculata , and is very handsome ; the sepals, 
petals, and column are covered with numerous purple 
freckles rather than spots, which, as the flower fades, run 
together, as if their colouring matter were dissolved ; so ' 
that at last the flower becomes of a dull wine-red tint. 
This is apparently the S. Lindleyi of Zuccarini. Most 
of the varieties are very sweet-scented.

ciously sweet-scented flowers, which are pale yellow, with 
a pair of dark eyes at the base of each petal, and a few 
crimson dots elsewhere on them and the sepals. The 
lip is deep yellow, and spotless on the hypochilium, while 
the epichilium and column are thickly sown with crim- 
son dots. It is certainly the Epidendrum grandiflorum 
of Humboldt, hitherto erroneously referred to S. insignis. 
Mr. Hartweg, who found it near Quito, has introduced
