1. Eleocliaris obtusa; radice fibrosa, culmis cæspitosis erectis teretibus inferne arete
vaginatis glabris striatis, vaginis oblique truncatis mucronulatis, spiculis ovato-oblongis,
squamis oblongis apice rotundatis uninerviis glabris, stylo trífido, achenio obovato lenticu-

We agree with Gaudichaud in thinking the plant from the Sandwich Islands scai-cely 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 lævibus, culmo
angulato lævi foliis strictis carinatis duplo longiore. Brown, Prodr. FL Nov. Holl. p . 228.

Found both in Oahu and Oneeheow. This species belongs to the genus Trichelostylis, Lestib., but it
ought not to be pkced in a different one from F. dichotoma, or from oui- F. affinis.
1. Morelotia galinioeformis. Gaud, in Freyc. Voy. p . 416. t. 28.
This genus being lately established, and peculiar to the Saudu ich Islauds, w e shall here give its character :
M o r e l o t ia , Gaud.;—Spicula apice uniflora; squames complurcs undique imbricatæ, ovatæ, coucavæ, apice
aristatoe. Stamina 3, esserta, persistentia. Ovarium ellipticum, sessile. Stylus filifoi-mis, exsertus. Stigmata
3, plumosa. Fmctus ellipticus, osseiis, lævis, nitens, sulcis tribus longitudinaliter exai-atus.—Tho stems
are cæspitose, 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 u-ith the convolute apices of the squamoe.
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, hy 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, w ith that described by Gaudichaud, but the character given does not strictly accord
with the siiecimens before us. We therefore propose the following:—V in c e n tia ;—Spiculce subsoxfloræ.
Squames undique imbricatæ, carinato-concavæ; inferiores concavoe summaque vacuæ. Perianthiumiri\d\.ve.
SeteB hypogynæ nullæ. Stamina 3. Ovarium sessile, triangnlai-e, angulis acutissimis. Stylus 1, inferne
dilatatus, triangularis, pubescens, cum ovario continuas, superne trifidus. N u x triquefra, basi styli persistente
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 Machaerinu
restoides, from which, hoivever, this genus differs liy the absence of hypogynous setæ, and by the scales
imbricated on all side.s : from Zepidospcrma it is distinguished hy the nature of the perianth.
I . Rhynchospora lavarum; glabra, culmis cæspitosis erectis trigonis, foliis setaceo-
linearibus rigidis subcaiialiculatis, corymbis terminalibus e t axillaribus oligostachys, spiculis
trifloris, squamis obovato-oblongis obtusis uninerviis glabris mucronato-subaristatis, achenio
subelliptico lenticulari-compresso lævi glabro fusco rostrato. Gaud, in Freyc. Voy. p . 415.
T h . zpccteeas in t e . Cofi.ction snfficiently with tee ahove eharaetev. To ua, this species seems
closely allied to Ä. fusca.

We feel extremely doubtful about any of the synonyms. Our plant, judging by a soUtary imperfect spen-
men, is nearly allied to C. strigosus.
