robust species, above a foot in length, throwing out numerous 
stout stolones, three or four inches long. Habit very much 
that of L. atroviride, but apparently more decumbent. Caul- 
ine leaves near two lines in length; those of the branches 
somewhat shorter and narrower. Spikes about three lines 
long.

L. Macraei. Hook. et Grev. 
Caule stolonifero suberecto superne bi-tripinnatim ramoso, 
ramis brevibus, foliis horizontalibus ovato-oblongis obtusis 
margine superiore basi valde dilatato ciliato, stipulis folio oc- 
tuplo minoribus ovatis longe aristatis serratis, spicis elongatis, 
squamis ciliato-serratis. 
Has. Ceylon. Macrae, in Herb. Bentham.— Plant eight 
to ten inches long, or perhaps more, as the specimen in Mr. 
Bentham's Herbarium is not perfect. Leaves of the stem 
somewhat approximate, a line and a half long. The branches 
are about an inch in length, arranged alternately at intervals 
of half an inch: the ramuli are only two or three lines long. 
Spikes beautiful, an inch and a half long. 
L. ornatum. Hook. et Grev. 
Caule stolonifero suberecto? tripinnato, ramis elongatis 
plumosis, foliis oblongis horizontaliter pectinatis margine 
superiore denticulatis obtusis paululum falcatis, stipulis ova- 
tis denticulatis mucronatis, spicis subuncialibus. _ 
Has. Sumatra. Miller, in Herb. Banks. This very 
elegant plant resembles our L. Wallichii both in size and 
habit, but is at once to be distinguished by its unilateral fruc- 
tification. 
L. calostachyum. Hook. et Grev. ET : 
Caule stolonifero decumbente bi-tripinnatim ramoso, ramis 
elongatis, ramulis brevibus, foliis horizontaliter pectinatis lete

valde dilatatis ciliatis, stipulis ovatis denticulatis longe et 
oblique cuspidatis, spicis brevibus, acras denticulatis majori-
