A m e r . Monthly 
Mag. 4: 190. 1819. 
In a review of Nuttall's 
Genera Rafinesque changes 
the name Lepturus R. Br. to 
Leptocercus because of a 
genus of insects by the name 
of Leptura. 
Our one species, Lep- 
turus cylindrica (Willd.) 
Trin. (fig. 53), is intro- 
duced in salt marshes 
from San Francisco to 
San Diego. At matur- 
ity the spike breaks up 
into the 1-seeded joints. 
The species has no eco- 
nomic value. For other 
species that have been 
referred to Lepturus. see 
Pholiurus. 
43. Pholiurus Trin. 
{Lepturus of authors, not 
R. Br.) 
Spikelets 1 or 2 flow- 
ered, embedded in the 
articulate rachis and 
falling attached to the joints; glumes two, placed in front of the 
spikelet and inclosing it, coriaceous, 5-nerved, acute, asymmetric,
