plant as a different but closely allied species ; as it is. The charac- 

 ter upon which Brown distinguished the genus Lamprocarya from 

 Gahnia (that of not having a transversely grooved nut) only throws 

 the most closely allied species into different genera. 



525. Gahnia Beecheti (sp. nov.) : glaberrima ; culmo tereti laevi ; 

 foliis linearibus longissimis superne filiformibus reclinatis arete convo- 

 lutis margine scabris dorso aculeis parvis asperatis ; panicula (10- 12- 

 pollicari) spicis axillaribus (sesqui-bipollicaribus) multifloris ; bracteis 

 ut foliis ; bracteolis ovato-lanceolatis mucronatis, carina ciliata ; spira- 

 lis unifloris ; squamis ovato-lanceolatis acutis, intimis obtusiusculis ; 

 nuce oblonga obscure trigona flava nitida styli basi cuspidata intus 

 transverse sulcata. — On mountain ridges at 1,000 to 3,000 feet eleva- 

 tion. — Apparently most nearly allied to G. schcenoides of Tahiti. (M. 

 & B. 91 ; Remy, 136 ; Macrae.) 



526. Gahnia globosa (sp. nov.) : glaberrima ; culmo tereti hevi ; 

 foliis linearibus elongatis culmum superantibus convolutis subtus kevius- 

 culis, margine nervis supraque scabris ; spicis globosis axillaribus e spi- 

 ralis (18-25) unifloris arete congestis compositis ; bracteis e basi lata 

 lanceolatis acuminatissimis ; bracteolis ovato-lanceolatis acuminatis ; 

 squamis late ovatis orbiculatisve acuminatis, intimis obtusis ; nuce ovata 

 flava extus longitudinaliter rugosa styli basi cuspidata intus haud sul- 

 cata. — With the preceding. — At once distinguished by the dense 

 globose spikes in a short interrupted panicle, and the broadly ovate 

 squama?. Apparently often gathered by collectors, but by Hooker & 

 Arnott confounded with Morelotia Gahniaformis, Gaud., and by others 

 with Lamprocarya affinis, Brongn., &c. Probably identical with a 

 poor specimen of Seemann's, no. 672, from the Viti Islands, which 

 he has called L. affinis, Brongn. (W. T. Brighara.) 



527. Oreobolus furcatus (sp. nov.) : dense pulvinato-casspitosus, 

 ramosus, foliosus ; foliis basi vaginantibus nervosis dense imbricatis 

 lineari-subulatis acutis obtusiusculisve rigidis serrulatis ; scapo sulcato 

 terminali simplici vel furcato 1 - 4-floro ; bracteis foliosis ; bracteolis 

 scariosis ; perianthii foliolis ciliatis integerrimis. — On the summits of 

 the mountains of Maui and Kauai. — Most nearly allied to O. obtusan- 

 gulus, Gaud., from which it differs in its often several-flowered scape, in 

 the leaves being serrulate, etc. (M. & B. 436 ; U. S. Expl. Exped.) 



528. Scleria testacea, Nees, 1. c. 9, p. 303. (M. & B. 329.) 



529. Carex Commersoniana, Sieb. ex Kunth, Enum. p. 291.
