| WESTERN TIBET; alt. 11-13,000 ft., Thomson, &c.—DisTRIB. Westward to Asia 
Minor, Syria and Greece. 
Stem 3-4 ft., often very stou*, deeply grooved. Lower leaves 1-2 ft., upper narrow 
at the base.. Valves 4-4 in. long, quite entire in all Indian specimens, pale, flat, 
finely reticulate.— The Indian specimens with no tubercle resemble R. aquaticus, L., 
and those with a tubercle R. Patientia, and I do not see why all these should not 
be united. 
** Inner fruiting-sepals with very narrow margins and few or no teeth. 
2. R. maritimus, Linn.; Meissn. in DO. Prodr. xiv. 1. 59; annual, 
leaves lanceolate narrowed into the petiole, panicle leafy to the top, valves 
rhombic- or oblong-ovate with a lanceolate tip all with an oblong tubercle 
unarmed or with 2-3 long needle-like spines. FV. Dan. t. 1208. R. palus-

Stem 1-4 ft., angled and deeply grooved. Leaves 3-10 in., petioled, base always 
narrowed into the petiole. Wahorls of flowers lax or dense, many- or few- d, 
Fruiting perianths all unarmed, or, on the same plant, some armed and some unarme : 
yellow brown when ripe, tubercle smooth, with a narrow sometimes reticulate margin ; 
Spine sometimes 4 times as long as the valve, tip straight or slightly hooke Us ad 
fruit varies greatly in size and number and length of the spines or the v be" "red

to R. maritimus.

or leafless, fruiting perianths densely crowded in globose distant or co : 
fluent heads, turning black in drying, pedicels short, valves with very larg ° 
oblong dark tubercles and lanceolate tips, margins very wage an me
