nate, near the base opposite: flowers glomerate, 
tetrandrous: fruit deeply furrowed or four-winged, 
with a large 2-cleft apiculus. 
Malabar? The exact station is not given, but I 
think it is from Malabar. This species is readily 
distinguished by the fruit from all except the follow- 
ing, which it greatly resembles in that and some 
other respects, but is distinguished by the procum- 
bent habit and more ovate leaves, the other being 
erect, with lanceolate ones. 
48. P. tetraptera (R. W. 42), erect, or ascending, 
ramous, leaves membranous, pilose, nearly all alter- 
nate (a few of the lower pairs only opposite), longish 
petioled, elliptico-lanceolate, acute at both ends, or 
sometimes ovato-lanceolate, upper ones much smaller 
aud narrower than the lower: flowers few, glome- 
rate, axillary, sessile, tetrandrous : fruit in the lower 
axils prominently ribbed, in the upper ones usually 
broadly 4-winged. 
Iyamallay and Bolamputty Hills, Coimbatore, flow- 
ering August and September. 
Both these species are rather variable, but they 
seem to retain their respective habits and are no 
doubt quite distinct : though the fruit, which is pecu- 
liar, be the same in both. 
49. P. Johnsonana (R. W. 47), decumbent, stems 
slender filiform, somewhat strigous: leaves longish 
petioled, pilose, alternate, from oval obtuse at both 
ends to ovato-lanceolate, sub-acute, floral ones reduc- 
ed, petiols slender filiform: flowers few, axillary, ses- 
sile: males tetrandrous with a conspicuous rudimen- 
tary pistil, woolly at the base: fruit ovate, compress- 
ed, furrowed or broadly 4-winged and beaked. 
Cochin, Malabar, Rev. E. Johnson. This seems 
a very distinct species, spreading flat on the ground, 
rooting for some distance round the root with flori- 
ferous extremities slightly ascending. The larger 
leaves scarcely exceed an inch in length and are 
about half as broad. 
_ 50. P. pyramidata (R. W. 48), straggling, ascend- 
ing or erect, branches slender, 4-angled, rather deeply 
furrowed between; lower pairs opposite: leaves al- 
ternate or the first few pairs opposite, progressively 
diminishing in size from the base to the apex, where 
they almost disappear; lower ones short petioled, 
ovato-lanceolate; upper ones sessile, linear acute, all 
rough and sprinkled with a few longish adpressed 
aA 
hairs above and strigosely pilose beneath: stipules 
broad cordate, cuspidate : flowers few, axillary, ses- 
sile, tetrandrous: calyx fringed with long bristly 
hairs, rudimentary pistil woolly at the base: fruit 
ovate, furrowed or broadly 4-winged. 
Quilon, Malabar. These two species are very 
unlike in appearance, though so nearly agreeing in 
the characters of the flower and fruit.

Parietaria sonneratii, Poir, seems, from the descrip-

Parietaria Judiaca, according to Poir's description, 
is a species of Forskalio.
