"S. pedunculis axillaribus et tenninalibus tristachyis, spicis subglo- 
bosis, pedicellafis, foliis filiformlbus, hispidulis. 
"Culmi palmares, spithamsei, angulata. Folia distantia 2 — 4 in 
culmo, superiora culmo longiora. Pedunciili axillares solitarii, ut terr 
minales interdum, qui gemini plerumque, poUicares vel minores, mon- 
ostachyi laxi. SpicEe magnitudinas seminis Coriandri, squamis subro- 
tundis fuscis. Flosculi 3. Stylus bifidus, purpureas. Semeni globo- 
sum undulato-rugosum. — In Carolina? Herb. Lamarck.^^ — Vahl. 
Obs. This plant has not been found by any N. American 
botanist, and it is somewhat doubtful whether Lamarck's speci- 
men was received from this country. It cannot be a Schcenus, 
as that genus is now restricted, but is rather a species of Rhyn- 
chospora, or perhaps of Psilocarya. 
2. ScHffiNUS SETACEUS, Vahl, enum. 2. p. 219 ? (not of Muhl.) ; 
Pursh, fl. 1. p. 46. 
" S. pedunculis axillaribus terminalibusque subtrifloris, culmo trigono 
foliisque setaceis. 
"Culmi pedales, vel minores, 1 — 2-nodosi. Folia 2 — 3, culmo bre- 
viora remotissima. Pedunculis e.x axilla superioresolitarius, terminalis 
plerumque gemini cum folio setaceo. Spicae 2 — 6, subulats pallide 
fuscse, squamis infimis ovatis mucronatis. Stamina 2. Stylus bifidus. 
Semina subrotunda, rugosa, bidentata. — In Surinamo, Caribseis, Caro- 
lina." — Vald. 
Obs. This species was introduced into the North American 
Flora by Pursh, on the authority of Vahl, but none of our bota- 
nists have found the plant. The description here quoted was 
probably taken from West Indian or Surinam specimens. 
Schcenus setaceus is the type of the genus Spermodon of P. 
de Beauvois and N. ab Esenbeck, the character of which is 
thus given by the latter writer : " Spiculae polygamy aut her- 
maphroditas, plurifloras. Stylus bifidus, basi bulbosus. Peri- 
gynium tubulosum, truncatum, cum basi fructus concrescens.
