in a sub-verticillate manner, and spread a little from 
the stem. There are no leaves on the underside of 
the prostrate stems. A very distinft species, that grows 
in swamps in humus, in which the stems are often found 
embedded by the fresh deposits. 
General distribution. —Madagascar, Hongkong, Cey- 
lon, Bourbon, Mauritius, Florida, Reunion, South Africa, 
New Guinea, Angola, and Tropical America from the 
United States to Brasil, but only Guadeloupe of the 
West India Islands.

p. 646. Plumier t. 165, B. — Stems repent, rooting here and there and 
branching laterally, 2-3 ft. 1. cylindric. Leaves lax, showing the stem 
freely between. Branches erect, freely again branched, repeatedly so, but 
not in a dichotomous manner. Densely clothed with leaves, which 
are in several series, rather stiff, subulate, £ li. w., i|-2 li. 1. with a hair- 
point, incurved. Fertile branches 1-3 in. 1., slender, terete, erect, with 
minute verticillate leaves at intervals. Spikes in pairs or alternate, 
2-6 in all to a branch. Bracts ovate-acuminate, attenuated, undulate- 
margined, somewhat spreading. 
A very stiff species both in stems and leaves, but 
variable in its degree of branching: in some cases lax, in 
others very dense, and having the branchlets short. 
The stems of the spikes are several inches high and de- 
crescent in size upwards, and thinly clothed with minute 
subulate leaves. The spikes have shorter pedicils from \-2 
in. 1. The leaves quite conceal the stems of the ordinary 
branches, though not of the primary and final ones. 
General distribution — Widely spread over most of 
the tropical and temperate regions of the world ; parti- 
cularly abundant in the West Indies and South America. 
ft Spikes sessile on normal branches. — Species 3-4.
