Costus, according to Mr. Brown, may be known at 
once from its coordinate genera by the structure of the pe- 
tiolar sheath, which is continued beyond the insertion of the 
leaf in the form of an ocrea (sheathlike bracte); and spe- 
cially from the closely kindred Hezcenras by the close- 
Spiked inflorescence, and petalshaped filament which is 
broader and longer tban the intramarginal anther. 
The subject of our drawing was sent us by Mr. Gowen, 
having flowered in Lord Caernarvon's hothouse at High- 
clere; where it had been grown from seed obtained from 
Dr. Wallich of the Botanic Garden at Calcutta, and in- 
scribed “ a new species of Costus from Nepal" We can 
discover no difference from the established speciosus, except 
the narrower foliage and fuller red of the bractes and calyx. 
The two may however be really distinct ; though we do not 
think it expedient to separate them without a comparison 
of the two in the fresh state. 
The stigma consists of two small shallowish transversely 
widened opposite lamina closing together like lips; ¿he 
Front one concave with a rounded entire border, the bück 
one convex with a border indented in the form of a crescent, 
the horns of which extend beyond the circumference 
of the front one; behind this at its base appear two short 
teethlike parallel upright pointed excrescences continued 
from their bases in a raised angle down the back of the style: 
these we take to be the rudiments of two filaments which 
have ascended the style in this way instead of keeping their 
station at the base, as is more usual in the order. 
The plant has been likewise raised by Messrs. Colvill, 
at Chelsea, from Nepal seed.
