The affinity of this plant is with C. bulbosus, Vahl, from which the habit, the absence of 
the bulbil, the narrow leaves, the longer mucro of Ше glume, and the shape of the fruit 
readily distinguish it. The plants grow closely together, forming a tuft; about five 
spikelets are loosely aggregated at the summit of the culm. 
C. ATRACTOCARPUS, n. sp. ; radicibus pluribus sublanatis ; culmis basi bulbosis, gracilibus 
glaucis subpedalibus striatis teretiusculis; foliis copiosis angustissime linearibus 
acutis glaucis, culmis multo brevioribus, vaginis striatis brunneis basi reticulatis ; 
involucralibus 1-2 sepius spiculis brevioribus angustissime linearibus striatis basi 
parum dilatatis; spiculis 1—8 erectis linearibus uncialibus, 12-floris et ultra ; squamis 
linearibus lanceolatis angustis multistriolatis laxiusculis sanguineis, carina viridi ; 
stylo longissimo trilineali, profunde trifido basi flexuoso pallido; caryopsi fusiformi 
subeylindrica, albescente bilineali.

The few long, slender, erect spikelets, the very long deeply-cleft style, the nearly 
cylindrical caryopsis tapering at both ends, distinguish this plant from its allies. It 
has some affinity with C. rwpestris, Kunth, but the spikelets are not flattened. The culms 
about 8 inches high, the leaves 2 inches in length.

The base of the culms are hard as wood and tuberous; the tubers have a pleasant 
aromatie smell, and are used frequently by the natives for intestinal pains. 
In Ashantee, according to Dr. Bowdich, it is administered as an antihelmintic. 
The plant is widely distributed over the tropics of both hemispheres.
