sharply indented. They are provided with spines. The bracteolae are 
narrow and lanceolate. The upper sepal is entire, broadly ovate, nearly 
as long as the corolla; the lower one is also broad but smaller, and bi- 
partite above. The inner sepals are very narrow and lanceolate. The 
corolla is bright rose-coloured, with three lobes, The bracts and sepals 
are silvery-green streaked with rose-colour. The plant is closely allied 
to Acanthus Dioscoridis, according to Boissier's description. The differences 
are that the leaves of Acanthus Perringi are grey-green instead of bright 
green. The stem is very short and the leaves sessile. The stem leaves 
are extremely broad and arranged in an oval, not a circular form. They 
are somewhat broader than the root-leaves. The bracts are broad and 
ovate; they lower sepal is broad and not narrow or linear in shape.

I should be elassed, as our description will show, closely with 5. 
prolifer (R. Br.) Cogniaux (cf. Fl. Bras., Orchid., V, pp. 10—17), which, 
like S. Cogniawxiana, has the chin of the flowers but slightly marked, a 
characteristic which at once caused me to assign the plant to this genus. 
The difference between the two species is easily seen: in S. prolifer the 
leaves are about 3/, to 1! inch long, and from 2,5 to 5 mm (about 1/10 
to 1/, inch) wide, while in our plant they measure 2!/, to 4*/, inches long 
by 2 to 3 mm (!/, to !/, inch) wide, the latter therefore are narrower 
and longer. In S. prolifer the sepals are pointed, the petals subspatulate; 
obtuse, the lip emarginated; in S. Cogniauxiana, the sepals are pointed, the 
petals subacute, the lip brodered to the top. What still further differentiates 
the two plants is the length of the ovary, which in the older species, figured 
in 1824 by Lindley in the Botanical Register (t. 825), is very short, about 
4 mm (or */¿ inch) long, and with bracts surrounding it to the top; in
