With these brief memoranda, explanatory of the 
principles which guided me in the construction of the 
following Clavis and characters of the species, I bring 
this hurried and imperfect monograph to a close, 
together with the work of which it forms a part, not 
however without expressing the hope that the latter 
may prove the means of inducing néw inquirers to 
enter this extensive field of research, by lightening 
the labour of gathering and storing the rich harvest 
that still remains to be reaped. So rich indeed is the 
Indian Flora that, did cireumstances permit, I could 
here, in Coimbatore, with the materials readily within 
my reach, commence a new series, and without re- 
producing a single species already introduced, carry 
on the work, I believe, through other 2000 plates. 
Povzorzi.. (Gaud., Bennett.) 
Gen. CHAR. Flowers monoicous, rarely dioicous. 
Male. Perianth 4-5- rarely 3-parted, stamens 4-5, 
rarely 3: rudimentary pistil minute or wanting. Fe- 
male. Perianth tubular, contracted at the apex, per- 
sistent, enclosing the seed or nut: at maturity sul- 
cately ribbed or 2-3-4-winged, bidentate at the 
apex. Style short or none: stigma prolonged, filiform, 
glandulose on one side. Nut ovate, crustaceous, 
fragile. Seed erect, rather sparingly albuminous. 
Embryo axile, inverse; radicle cylindrical, remote 
from the hilum. 
_ Herbaceous, suffruticose or shrubby plants: creep- 
ing, procumbent, ascending or erect. Leaves ternate- 
ly verticelled, opposite or alternate, entire or rarely 
serrated, 3-nerved, or triple or quintriple-nerved : 
variously pilose, very rarely glabrous. Flowers ax- 
illary, glomerate, short pedicelled. Clusters at first 
nearly all males mixed with a few sessile, ovate, rib- 
bed, wingless fruit, afterwards, towards the ends of the 
floriferous branches, the male flowers diminish in 
number and are replaced by female ones producing 
winged fruit. 
Oss. The term Fruit, as here applied, is meant to 
include the nut or achænium together with its enclos- 
ing periaith, as seen when it separates at maturity 
from the parent plant. 
Ons. Ihave said above that the lower glomerules 
are made up of male flowers mixed with * wingless 
fruit" not female flowers. This is strictly correct, the 
female flowers precede the males and are besides so 
small that they are nearly invisible until they have 
attained an advanced state of maturity, while a suc- 
cession of male flowers continue opening for a length 
of time and before they have all passed away the first 
seed are mature and dropping off. 
This fact, which I have often observed, leads me to 
suspect that most, if not all Mr. Bennett's supposed 
dioicous species, are monoicous, but the specimens 
young and the sessile fruit concealed among the pedi- 
celled male flowers. It is not until long after, that the 
winged fruit, which are mainly confined to the extre- 
mities of the floriferous branches, are fully developed.
