Differing from L. ruscifolia in having a second sterile lemma. 
This species has been confused with L. ruscifolia and was included 
under that name in Grasses of the West Indies, in which the following 
statement appears: “In all the Trinidad specimens the spikelets con- 
tain a second sterile lemma, a character not found in any other 
species known to us. This second sterile lemma equals the first, 
contains a hyaline palea, and infolds the fruit rather more closely 
than the sterile leomma.commonly does in other species. The fruit 
borne one joint higher on the rachilla consequently faces in the direc- 
tion opposite to the one usual in Paniceae; that is, the palea side of 
the fruit faces the second instead of the first glume.’ <A reconsid- 
eration ™ of the group led the writer to the conclusion that, ‘‘we have 
here a distinct species, for not only is there this unusual character of 
a second sterile lemma but also a distinct geographical range. Of the 
eroup to which it had been referred, all the specimens from Trinidad, 
the lower Orinoco, and eastern Brazil have a second sterile lemma; 
outside of this range, that is, north and west, there is but one sterile 
lemma in all the specimens examined. In other respects, such as 
shape of blades and panicle, pubescence, and shape and size of spike- 
lets, this species does not differ from L. ruscifolia. The specimens of 
L. anomala agree closely among themselves in all these characters, but 
also agree with many specimens referred to the more variable species, 
L. ruseifolia.”

Spikelets oblong-conic; first glume small, much shorter than the 
spikelet; second glume broad, inflated-saccate, strongly many-nerved; 
sterile lemma narrower, flat, fewer nerved, its palea nearly as long, 
often subtending a staminate flower; fertile lemma stipitate, elliptic, 
chartaceous-indurate, the margins inrolled, the palea not enclosed at 
the summit. Aquatic or subaquatic perennials or annuals, with 
dense narrow panicles.
