species. Tt is not improbable that in old specimens 
winged fruit may be found. 
$ 4 Leaves ternately verticelled: flowers pentan- 
drous,—upper leaves conformable or simply re- 
duced in size. 
8. P. tomentosa (R. W. 11), stem and under surface 
of the leaves tomentose : leaves sessile, ternately ver- 
ticelled, oblong, ovate-lanceolate, rounded or sub-cor- 
date at the base, acute or sub-acuminate ; scabrous 
above: stipules reflexed : flowers numerous, pentan- 
drous, subsessile : fruit wingless, ribbed. 
Neilgherries, flowering August and September. I 
find no trace of wings in this species, though the spe- 
cimens seem to have attained an advanced state of 
maturity, but still I cannot feel certain on this point 
_ as male flowers so greatly predominate, which seems 
to indicate that they are still far from maturity. 
9. P. heterocarpa (R. W. 13, 14), erect, sparingly 
branched, stems terete, glabrous : leaves ternately ver- 
ticelled, triple-nerved, short petioled, narrow lanceolate, 
acuminate at both ends ; smooth, downy above, hoary 
beneath : flowers numerous, sessile, pentandrous : fruit 
varying from slightly ribbed to broadly winged, the 
winged ones deeply cordate at the base. 
Western slopes, Neilgherries, flowering Decem- 
ber. I have two forms of this plant the one here 
described clothed with short pubescence, the other 
glabrous, but both free from roughness on the surface : 
the leaves are from 3 to 5 inches long and about 2 of 
an inch broad, ending in a long tapering acumen. 
This being among the first examined in which I 
found two forms of seed, I named it accordingly ; the 
discovery of so many others similarly circumstanced 
has rendered it less appropriate. 
_ 10. P. Bennettiana (R. W., Ic. 1978), erect, spar- 
ingly branched: stem and upper surface of the leaves 
scabrous : leaves ternate, short petioled, ovate lanceo- 
late, slightly unequal-sided, obtuse or sub-cordate at 
the base, ending in a long tapering acumen; pilose 
above, densely pubescent or sub-tomentose, especially 
on the nerves, beneath: flowers numerous, subsessile, 
5-androus : fruit in the same fascicles ovate, sim- 
ply ribbed, or broadly two or three winged; the two 
winged ones rather deeply cordate at the base. 
Neilgherries, Ceylon ? Courtallum ? 
I feel still uncertain whether to view this simply as 
a variable plant or to suppose that I have combined 
more than one species. "The form represented in the 
plate is that which I consider the true one, all except 
the winged fruit which was taken from too young a 
specimen and had not attained its perfect form. 
Among the forms I have referred here, are some with 
much narrower and more tomentose leaves, but all 
agreeing in their scabrous upper surface. The Ceylon 
and Courtallum plants differ in the above respects 
from the Neilgherry ones. The slight inequality of 
their sides, gives the leaves a somewhat faleate ap- 
pearance which is readily observable in the speci- 
men, though scarcely shown in the figure. 
$ 5. Leaves ternately verticelled: flowers 4-androus. 
* Upper leaves reduced, not bract-like. 
11. P. ternata (Bennett, 7), erect, sparingly branch- 
ed; stem and under surface of the leaves hoary: 
leaves all alike, but smaller towards the extremity, 
subsessile, broadest and slightly cordate at the base, 
lanceolate, acute; pilose above, somewhat tomentose 
beneath: flowers 4-androus, fruit winged or simply 
ovate, ribbed. 
Courtallum. This principally differs from the two 
preceding species in being tetrandrous, a distinction 
which I think it probable more extended acquain- 
tance with these species will show to be of scarcely 
specific value. Among the specimens I have refer- 
red to Bennettiana, perhaps erroneously, I find some 
with tetrandrous flowers, but I have not met with 
pentandrous ones on this. 
19. P. longifolia (R. W., 6), erect, stem 4-angled, 
scarcely branched: clothed with rough hairs: leaves 
ternate, subsessile, linear lanceolate, broadest, and sub- 
cordate at the base, taperingly acuminate at the 
apex ; pilose on both sides, scabrous above, the under- 
surface netted with dark coloured somewhat promi- 
nent veins: fascicles few-flowered, flowers tetran- 
drous, fruit broadly winged and deeply cordate. 
Courtallum, September. Leaves about 6 or 7 
inches long and scarcely 1 broad, membranous, the 
hairs with which their surface is thickly clothed so 
fine that until closely examined they look as if glab- 
rous. 
13. P. Wightii (Bennett, 8), erect, scarcely branch- 
ed, terete: leaves sessile, opposite or ternate ; narrow 
linear lanceolate; tomentose beneath, downy and 
slightly rough above, the extreme ones considerably 
smaller: flowers 4-androus : fruit broadly winged, cili- 
ate, cordate at the base, somewhat forked at the apex. 
Pulney Mountains, September. E 
This is a very distinct species from the preceding, 
but very nearly approaches ternata, in every thing 
except the great diminution in size of the floral leaves 
which, however, I esteem a good character. 
14. P. concinna (R. W., 9), erect, terete, glabrous, 
leaves opposite and ternate, sessile, lanceolate, spread- 
ing, acuminate, the extreme ones much smaller and 
cordate, acute, all downy on the nerves beneath and 
scabrous above ; flowers tetrandrous, axillary, sessile, 
few : calyx lobes lanceolate acute: fruit both ovate 
and winged. 
Courtallum. The leaves in this species are spread- 
ing, rather rigid, below exactly lanceolate, but some- 
what prolonged at the point into a fine acumen, to- 
wards the extremities of the older branches, short, 
broad ovate cordate. It is a neat pretty looking 
plant in the herbarium, whence the specific name. 
* * Upper leaves bract-like. 
15. P. aspira (R. W., 18), erect, very ramous, the 
terminal shoot long and slender; stem and branches 
terete, very rough : leaves ternate rarely opposite, ses- 
sile, broad ovate-cordate, acute, 5-nerved at the base; 
rough on both sides but especially above; those on 
the floriferous ramuli much reduced, often almost to 
mere scales, cordate acute: flowers 4-androus, fruit 
all ovate, ribbed, not winged. 
Anamallay Hills; flowering in July. One of the 
most | species of the genus; rer ووی‎ by 
its rigid numerous harsh broadly ovate cı leaves, 
its slender floriferous Peg or the terminal 
one sometimes from 12 to 18 long: fruit very 
small, numerous, ovate, and ribbed throughout.
