534 FLORA NIGRITIANA. 
by Vogel, has a three-valved, three-celled capsule, echinate, like 
those of a Canna, but with single black arillate seeds in each cell.

These specimens, as far as can be ascertained in the dried 
state, where the texture of the flowers is so very delicate, 
agree with the plant which Afzelius describes under the 
above name as the common Amonum of the Guinea Coast, 
except that the flowering scape varies from an inch to near 
a foot in height, bearing at its summit several large white 
flowers, tinged with purple towards the apex, and the pulpous 
fruit (perhaps not yet ripe) is not above 14 in. long. 
The other West Tropical African Scitaminee are: Amomum 
grandiflorum; Sm., A. Afzelii, Rose., A. latifolium, Aft, and 
Zingiber dubium, Afz., all from Sierra Leone; and Schumacher 
and Thonning mention the Zingiber officinale, Rosc., and Cur- 
cuma longa, Willd., as cultivated. 
CVI. IRIDEE. 
Of this Order there are not as yet, as far as I am aware, any 
species published from West Tropical Africa, and I have seen 
specimens of but one species, gathered south of the Line by 
Curror. It belongs apparently to some unpublished genus 
allied to Gladiolus, but the flowers are too rotten for exami- 
nation. There is also in Don’s Sierra Leone collection a frag- 
ment of another plant, but it has the appearance of a Cape 
species, probably from some garden. 
CVTI. AMARYLLIDEX. 
There are no specimens in the collection, and the following 
are the only species recorded from the region. Hemanthus
