Widely dispersed, indigenous in Europe and N. Asia, probably a colonist elsewhere. 
The Himalayan and Tibetan specimens are intermediate in several points between 
P; aviculare and p. Bellardi, as these are defined by Boissier; the leaves are not 
veined as he describes them in aviculare, nor are they acute as they should be in 
P. Bellardi ; and though the branches sometimes run out into a subspicate in- 
orescence, this is not so slender and interrupted as in true Bellardi. Boissier gives 
“India borealis” as a habitat for the latter plant; but I have seen no specimens.

. A small annual, with sometimes rosy flowers, crowded leaves and hyaline stipules, 
1 in. long, very different from P. aviculare in the sessile perianth cleft at the top only, 
and in the small broad short shining nut.—Meissner has cited “ Kumaon, Strachey 
and Winterbottom, No, 49,” as a locality for P. Olivieri, Jaub. and Spach. I have 
eus 20 specimens, and suspect some error. The calyx-lobes of P. Olivieri (which is 
Sy nonym of p, polycnemoides) equal the tube. i
