Mr. Macrae, 



55. C. RUBiGiNosus, Hook.Jil.; culmo aphyllo semitereti, involucro 6-8-phyllo,

 Hab. Charles Island, Charles Darwin, Esq. 



Erectus, glaberrimus, simplex, textura spongiosa, bipedalis. Culmi erecti, nudi, semiteretes, 

 superne canaliculati, siccitate sulcati, sulcis nunc transverse rugosis, pallide virescentes, 

 glaberrimi, sub 2 lin. diam. Involucri foliola lineari-elongata, spithamasa et ultra, bi- 

 tridentata, flexuosa, basi concava, brunnea, vaginantia, deinde plana, versus apices tri- 

 quetra, marginibus carinaque argute ciliato-dentatis. Umbella simplex, radiis 4-5 

 plerisque 2-3-uncialibus, semiteretibus, aliis brevioribus et 1-2 brevissimis, capitulis in 

 axillis sessilibus. Capitula globosa, solitaria, rarius gemina, f unc. diam., e spicis 

 30-40 glomeratis formata. Spiculae patentes, valde compressce, \ unc. longae, lineari- 

 oblongae, obtusae, 2 lin. latae. Squamae arete et distiche imbricatae, patentes, valde 

 compressae, dorso nervosae ; nervo lato, obtuse carinato, virescente, in rostrum validum 

 recurvum producto, scabrido, lateribus 2-nerviiB, herbaceis, rubiginosis. Stamina 3 ; 

 filamentis planis, membranaceis ; antheris inclusis. Ovarium triquetrum, obovatum. 

 Stylus basi vix incrassatus, deciduus, in ramos 3 flexuosos desinens. Achaenium nigrum, 

 squama ^ brevius, trigonum. 



A very distinct species, belonging to the section Haspan of Kunth. In the 

 sharp recurved apices of the squamae it approaches C. injlexus, the spikes 

 assuming a similar squarrose appearance. Unfortunately the specimens are 

 destitute of leaves.

 boldt ^ Bonpland. 



Erectus, glaberrimus, basi foliosus. Radix fibrosa, fibris crassiusculis, fuscis. Culmi soli-
