S. Princeps, Bolus in Hook. Ie. Plant. t. 1729. 
This beautiful plant has been described by Mr. Bolus 
(who regarded it as a new species).as one of the hand- 
somest of the genus, with bright carmine flowers deepening 
to crimson on the back of the lip. In his admirable de- 
scription, he says that it is allied in habit and floral 
structure. both to S. carneum and membranaceum, and 
occupies the same kind of wet sandy dunes near Port 
Elizabeth as are affected by the former near Cape Town. — 
He distinguishes it from S. membrqnaceum “by its more 
- robust habit, by its much wider lateral sepals, by its ° 
ine 
obtuse odd sepal, by its emarginate stigmatiferous lobe, ae 
but especially by the shape’ of the rostellum, which has a 
long and sharp intermediate tooth in front, so that the — 
¥ 
apices of the ‘glands nearly touch each other, whilein S,  ~ a 
membranaceum the rostellum has a wide semicircular lobe © 
in front, so that the glands are widely separated.” Not-' 
withstanding these characters, Mr. N. E. Brown, who has 
carefully studied the specimens of Satyriwm cucullatum in 
Thunberg’s Herbarium, upon which S. membranaceum 
-was founded, and which were procured at Port. Elizabeth | - .
