The genus Chorizandra comprises two species, natives of Australia and New Caledonia. 
These are wiry xerophytic plants, with a few terete leaves at the base, or leafless, 
the involuere consisting of one or two terete acute, erect, foliar organs. The plant above 
described differs conspicuously in having a false whorl of broad leaf-like organs sur- 
rounding the solitary head. "The stems are borne singly on a fairly stout woody rhizome, 
and at the base are enclosed in a mass of brown sheaths. They are 4-angled, an unusual 
thing in Cyperacee. The head of flowers is half hidden in the bases of the involucral 
leaves, and consists of a compact mass of spikelets with stiff, cuspidate, blackish-brown 
bracts at the base. The spikelets are composed of a mass of glumes, the outer ones 
broad, acutely keeled, narrowed and flat in the lower part, the upper ones gradually 
passing into lanceolate nearly flat pale glumes tipped with reddish brown. In each of 
these there is a single stamen, except the terminal one, which bears a pistil. In Bentham 
and Hooker's * Genera Plantarum” (iii. 1057), the description of the spikelets is given as 
*Spieule multiflore, floribus omnibus hermaphroditis (vel apud auctores nonnullos 
in capitulo androgyno numerosa 1-floree uni-sexuales). I do not think there is any 
doubt as to the structure of the spikelet; at the base are two or three empty glumes, 
or bracts, of a somewhat peculiar shape, broad, oblong, spathulate-hooded, and stiff ; 
the rest (very numerous) are simply lanceolate, and each subtends and slightly curves 
round a single stamen, representing a monandrous flower, except the terminal one, 
Which half encloses the pistil, representing a monogynous flower. 
Suringar (Z. c.) describes and figures what is evidently intended for this plant, under 
the name Capitularia involucrata (nov. gen. et sp.). His specimen seems to have been 
a poor one, and his account of the inflorescence is not very clear, as he seems to have 
misunderstood the structure of the spike. However, his figure of the whole plant is 
sufficiently clear to identify it; it was obtained at Alkmaar by Versteeg. ; 
The genus Chorizandra, with the African Chrysothrix and the Asiatic Lepironia and 
Scirpodendron, seem to me to form a somewhat natural group, each spike possessing a 
number of monandrous flowers with one terminal female flower.
