Branches many, stont, flexuous, 2-6 in., from a woody stock, scaly at the base, but 
not rooting. Leaves rarely 1 in., elliptic-lanceolate, almost succulent ; stipules 
silvery, obtuse, acute or acuminate. Perianth very thick, lobes with white margins. 
Nut jy in. long, ovate, compressed or obtusely trigonous, black, shining, usually com- 
pressed and obtuse in Indian examples.—Boissier adopts the later name of P. alpestre 
for this, because Meissner described his cognatum from-a variety (P. rupestre, Kar. and 
Kiril.) with longer pedicels. He further refers the Himalayan plant to Meissner s 
var. ammannioides, a Persian form with shorter internodes, and smaller narrower 
leaves ; but the majority-of Indian specimens do not differ from the common form. 
6. P. paronychioides, C. A. Mey. En. PI. Talysch. 20; rootstock 
very stout woody, branches short tufted erect and ascending scaberulous 
young concealed by the stipules, internodes very short, leaves linear with a 
deciduous mucro margins recurved, stipules large hyaline lanceolate tumid 
2-nerved tip lacerate, pedicels short jointed at the tip, fruiting perianth 
urceolate lobes rounded shorter than the tube 2 outer awned at the back.

Root or rootstock often as thick as the middle finger, tortuous, woody, with chestnut 
scaling back. Stem 1-4 in., fragile, white or red-brown, not grooved. Leaves jin., 
nerveless, glabrous or scaberulous; stipules in young plants concealing both leaves and 
stem, lower with often two very faint included nerves, upper with two strong exserted 
ones. Fruiting-perianth as in P. cognatum, but shorter. Nut 4, in., broadest in the 
middle, black, smooth.—The character of the dorsally mucronate outer sepals appears 
pretty constant, though not referred to by authors. 
7. P. salicornioides, Jaub. & Spach. Ill. Pl. Orient. t.123; shrubby, 
scaberulous, branches stout divaricate grooved at length spinescent and 
leafless, internodes crowded, leaves minute fleshy linear ovate or oblong 
rigid 1-nerved margin revolute, stipules short hyaline lacerate, perianth 
rosy, nut large thick opaque punctate. Meissn. in DC. Prodr. xiv. 1. 90; 
Boiss. Fl. Orient. iv. 1042. 
SCINDE, l'icary.— DISTRIB. Persia. 
The specimen is very imperfect, and I have taken much of the specific character 
from Boissier. 
** Root mostly annual (except some forms of P. plebejum). 
8. P. aviculare, Linn.; Boiss. Fl. Orient. iv. 1036; glabrous, branches 
procumbent or ascending grooved leafy, leaves elliptic or elliptic-oblong or 
-lanceolate obtuse flat nerveless, stipules shorter than the internodes hyaline 
lacerate many-nerved, flowers axillary, pedicel short jointed at the tip, 
perianth obovoid cleft to near the base, nut ovoid obtusely 3-gonous minutely 
rugosely striolate. Bab. in Trans. Linn. Soc. xviii. 114.° P. aviculare y- 
diffusum, Meissn. in DC. Prodr. xiv. 1. 97.
