Mariscus maculatus, Rcem. Sf Schult. syst. 2. p. 243. 
Root fibrous. Culms 3 — 8 inches high, cespitose, smooth. Leaves 
scarcely aline wide, shorter than the culm, often involute. Involucre of 
2 long leaves, and one very short one. Spikes usually 3, a little larger 
than a pepper-corn, closely aggregated. Scales very numerous, rather 
loosely imbricated, concealing the spike'lets, persistent, marked with 
minute oblong red dots, particularly on the inner side; midrib green. 
'SpikeUt composed of 2 squanmlsD; llie interior obtuse, often dotted like 
•the scales; the exterior (next the scale) very thin and delicate. Stamen 
always solitary. Style slender, longer than the nut. Nut 3 -sided, but 
the sides and angles aj-e so rounded that it appears nearly cylindrical, 
contracted into a neck near the base, yellow.

Obs. To the L. Humholdtiana of Nees ab Esenbeck 
\Hypoelytrum argentcum, Kunth, syn. 1. p. 149, not of Vahl,) 
this species bears a strong resemblance, but it differs in the 
scales, which are acute but not acuminate, and in the style 
which is bifid, not 3-cieft. Michaux states that our plant 
resembles Kyllingia triceps, but it undoubtedly belongs to the 
present genus, while K. triceps is a true Kyllingia. Muhlen- 
■berg's K. triceps appears to be merely K.pumila. 
6. FUIRENA, Rottb. 
Scales of the spike imbricated on all sides, one-flowered, 
awned. Perigynium single or double; the exterior (calyx), 
when present; consisting of 3 bristles, the interior (corolla) of 
3 unguiculate petaloid laminae, alternating with the bristles. 
Stamens 3. Style 3-cleft. Nut triquetrous, pointed with 
the remains of the style, abruptly contracted into a pedicel at 
the base. — Culms mostly simple, erect, articulated, angular, 
leafy (rarely with nearly naked sheaths) ; spikes subumbellate, 
axillary and terminal, mostly squarrose ; external lamina of the 
scale produced into a short awn or bristle.
