1. Scirpus maritimus. Linn. — Engl. Bot. t. 542. Spreng. Syst. Veget. v. 1. p. 210. 



2. Scirpus lacustris. Linn. — Engl. Bot. t. 666. Spreng. Syst. Veget. v. 1. p. 209. 



1. Eleocharis obtusa; radice fibrosa, culmis caespitosis erectis teretibus inferne arete 

 vaginatis glabris striatis, vaginis oblique truncatis mucronulatis, spiculis ovato-oblongis, 

 squamis oblongis apice rotundatis uninerviis glabris, stylo trifido, achenio obovato lenticu- 

 lari-compressiusculo lsevi glabro albido styli basi conica coronato. Gaud, in Freyc. Voy. 

 p. 414. — Scirpus obtusus. Willd. En. Hort. Ber. ? 



We agree with Gaudichaud in thinking the plant from the Sandwich Islands scarcely distinct from that 

 found in North America. 



1. Fimbristylis cymosa; umbella decomposita involucrum superante, spiculis globoso- 

 ovatis paucifloris, squamis ovatis, stylis trifidis nudiusculis, nucibus triquetris lasvibus, culmo 

 angulato lsevi foliis strictis carinatis duplo longiore. Brown, Prodr. Fl. Nov. Holl. p. 228. 

 Spreng. Syst. Veget. v. I. p. 202. 



Found both in Oahu and Oneeheow. This species belongs to the genus Trichelostylis, Lestib,, but it 

 ought not to be placed in a different one from F. dichotoma, or from our F. affinis. 



1. Morelotia gahniceformis. Gaud, in Freyc. Voy. p. 416. t. 28. 



This genus being lately established, and peculiar to the Sandwich Islands, we shall here give its character : 

 Morelotia, Gaud.; — Spicula apice uniflora; squamce complures undique imbricate, ovata?, concavse, apice 

 aristatse. Stamina 3, exserta, persistentia. Ovarium ellipticum, sessile. Stylus filiformis, exsertus. Stig- 

 mata 3, plumosa. Fiuctus ellipticus, osseus, Levis, nitens, sulcis tribus longitudinaliter exaratus. — The stems 

 are csespitose, erect, leafy, and cylindrical ; the leaves very narrow, linear. The panicles are terminal and 

 crowded. The fruit is deciduous, but remains for some time suspended by the filaments, which become 

 entangled with the convolute apices of the squamse. 



1. Vincentia angustifolia ; foliis angustatis linearibus culmo parum brevioribus. — Gaud. 

 in Freyc. Voy. p. 417. 



Gaudichaud named this genus in honour of Bory de St. Vincent, but as there is already Borya dedicated 

 to him, a second is, by all Botanical rules, inadmissible: we have, however, allowed it to remain, rather 

 than create confusion by altering it. — We believe there can be no doubt entertained of our plant being 

 identical, as a species, with that described by Gaudichaud, but the character given does not strictly accord 

 with the specimens before us. We therefore propose the following: — Vincentia; — Spicules subsexfloree. 

 Squamae undique imbricatse, carinato-concavse ; inferiores concavae summaque vacua?. Perianthium trivalve. 

 Seta hypogynre null*. Stamina 3. Ovarium sessile, triangulare, angulis acutissimis. Stylus 1, inferne 

 dilatatus, triangularis, pubescens, cum ovario continuus, superne trifidus. Mix triquetra, basi styli persis- 

 tente cuspidata. — To this genus belong Scirpus lavarum, anceps, and iridifolius, nor perhaps are there any 

 good specific characters to be found between them: they have all been usually referred to Machaerina 

 restoides, from which, however, this genus differs by the absence of hypogynous setse, and by the scales 

 imbricated on all sides : from Lepidosperma it is distinguished by the nature of the perianth. 



1. Rhynchospora lavarum; glabra, culmis caespitosis erectis trigonis, foliis setaceo- 

 linearibus rigidis subcanaliculatis, corymbis terminalibus et axillaribus oligostachys, spiculis 

 trifloris, squamis obovato-oblongis obtusis uninerviis glabris mucronato-subaristatis, achenio 

 subelliptico lenticulari-compresso lsevi glabro fusco rostrato. Gaud, in Freyc. Voy. p. 415.
