A CENSUS OF THE INDIAN POLYGONUMS. 
3^1 
I.-North-West Frontier: (i) Afghan border; Kurram 
Valley, Aitchison, No. 656! 
VI. — North-West Himalaya : (15) Kunawar ; Pangi, Stoliczha ! 
The many-nerved stipules, and the peculiar venation of the leaves 
with their revolute margins, make this species quite distinct. The 
Calcutta sheets are intermediate in character between Polygonum 
setosum Jacq,, and Polygonum luzuloides Jaub. & Spach, as 
described in Boissier’s Flora Orientalise vol. iv, pp. 1038-1039, and 
as figured in Jaubert and Spach’s III. Or.y it. 125 and 126. 
Bossier describes Polygonum luzuloides as very close to Polygonum 
setosum^ and the Calcutta sheets would support the idea that they are 
really one species. 
13. Polygonum tiibiilosum Boiss. 
L — North-West Frontier : No specimens in the Calcutta Her- 
barium.

13,^^ Polygonum polyciiemoides Jaub. & Spach. {Illustr. ii, 20 t. 120), 
Annual, glabrous, prostrate, much branched ; branches 7 cm. to rarely 
30 cm, long, filiform, flexuous, angled but not grooved, often finely 
scaberulous on the angles ; internodes short, 8 mm. to 16 mm. long, very 
uniform, but becoming very short towards the apex and entirely covered 
by the stipules. Leaves minute, sessile, alternate, fleshy, flat, entire, 
obsoletely i -nerved, mucronulate, 8 mm. long or less. Stipules 
delicate, membranous, white, hyaline, obsoletely 3-nerved, more or 
less dentate, the lower shorter than the leaves, the upper as long or 
a little longer and imbricating. Flowers axillary, solitary or in pairs, 
very shortly pedicelled. P^rz'^/zM-segments 5, 3 internal, 2 external. 
Stamens 8, inserted on the perianth- throat, unequal. Nut trigonous, 
very small, included, minutely punctate.
