l. Fimbristylis affin is; glabra, culmis csespitosis erectis tiiquetris, foliis angustissimis
fíaccidis, involucro 3-4i-phylJo, spicidis ovatis terminalibus paucis umbellatis centrali sessili
lateralibus longe pedunculatis, pedunculis involucrum «quantibus, squamis suborbiculatis
acutis trinerviis scariosis glabris, stylo complanato bifido m argine fimbriato, achenio obovato
lenticidare-compresso longitudinaliter striato.
This is very nearly allied to F. dichotoma and annua, Avhich have equally the leaves of the involucre
ciliated: but the whole plant is hu-ger, and differs from the former in its smooth culm and leaves, and
from the latter by the two, not three, stigmas.

This, Ml'. Collie observes, is frequent in the moist meadows of Tahiti.

Oui' specimens are very imperfect. Mr. CoUie states that it is used for making hats and women’s bonnets,
and has been probably introduced. Its vernacular uame is Tumarnu.

Our plant turns almost black in drying. At the base of many of the spikes, (not of aU,) we observe one
or two rather long white hairs, Avhich we presume are the set» of Mr. Brown.—Our specimens of P. prcecox
of Walt, from the late Mi-. Elliott, gathered in Carolina, we cannot distinguish from the present. This is
called in Tahiti Nonwha, and is exclusively used for carpetting the houses.

Most authors describe, and Pal. de Beauvois represents, the calycine glumes as three in number; whereas,
in our plant, they are constantly two. The lower of the two flowers in the spikelet appears to be male, the
upper one female.

We have not been able to refer this species to any described one. It approaches much to A . hirtus of
the South of Europe, but differs from that aud from almost every hitherto knoAvn species of the genus, by
the nearly total absence of hairs on the rachis ; these, indeed, are so short and so fcAv as to leave some doubt«
if it ought to be retained in Andropogon, although agreeing well in other points udth the reformed character
its given by Trmius.
