Camb. Brit. FI. ii. Plate 14.8. (a) Flowering shoot, (b) Ground-leaf. ( c ) Fruiting segments. ( d ) Fruiting 
segments from another plant (two enlarged). Cornwall (C. C. V.). 
Perennial. Stem about 4 — 7 dm. high, branched above ; branches short, suberect. Petioles of 
the lower leaves about 4 — 10 cm. long, usually much shorter 
than the laminae. Laminae of the lower leaves narrowly 
oblong or oblong-lanceolate, about 2’o — 2^5 dm. long and 
3 — 4 cm. broad, margins crenulate-undulate, narrowed at 
each end ; of the stem-leaves lanceolate ; of the inflorescence, 
larger than in R. glomeratus. Inflorescence branched, branches 
suberect, leafy in the lower half, whorls rather distant. 
Pedicels a little longer than the fruiting segments, jointed 
below the middle. Flowers in July and August. Fruiting 
segments larger than in R. glomeratus , about 4 mm. long, 
narrowly ovate-oblong, obtuse ; tubercles 3, broad, con- 
spicuous, reddish-brown, larger than in R. glomeratus. 
Achenes about 2 mm. long and i’o — 1*5 broad. 
Sea-shores in clefts of rocks, at the foot of cliffs, and on shingle. Local and rather rare ; 
Channel Isles, Devonshire, Cornwall. Specimens from Sussex which we have seen named R. 
rupestris are probably R. condy lodes x crispus. 
France — Normandy, Brittany, Vendde ; Spain — Galicia; ? Portugal.

leones : — Camb. Brit. FI. ii. Plate 149. (a) Flowering shoot. ( b ) Ground-leaf. ( c ) Persistent perianth- 
segments (enlarged), (d) Flowers (enlarged). Jersey (E. W. H.). 
Perennial. Stem about 5 dm. high. Ochreae appressed. Petioles of the ground-leaves about 
a third to half as long as the laminae. Laminae oblong, subcordate at the base, margin more 
coarsely and irregularly crenate than in R. condylodes , rather more obtuse at the apex, shorter 
than in R. condylodes , primary veins more numerous ; of the inflorescence, larger than in R. condy- 
lodes ; all with broad, dark-crimson veins even when very young. Pedicel jointed near the base. 
Flowers in July, about a week later than R. condylodes. Fruiting segments oblong, entire, somewhat 
reticulate, one with a tubercle. Achenes small, ovate, brown. 
This is an obscure and little-known plant. The “ Rumex sanguineus ” of the majority of botanists is simply an autumnal 
state of R. condylodes with more or less well-marked crimson-coloured veins. The leaves of R. sanguineus have broad, dark- 
crimson veins from the moment they appear above the ground in February; and these continue as a well-marked character 
until the aerial shoot perishes in late autumn. The two species are closely allied, as Bieberstein (FI. Taur.-Cauc. i, p. 288) 
states when founding the latter species ; but they are no nearer to each other than many other plants which are commonly 
kept as species, such as Salix phylicifolia and S. nigricans , Quercus robur and Q. sessili/lora, Betula alba and B. pubescens. 
The origin of R. sanguineus is unknown to us; and it is possible that the plant is of garden origin. It has long been 
cultivated in Europe, though now it is, at least in the British Islands, very rare. 
Waste places, roadsides, orchards; Channel Isles, Gloucestershire, Shropshire, East Riding of Yorkshire; 
Ireland — co. Galway. Doubtless elsewhere, but book-records of this plant are very dubious owing to confusion 
with the red-veined forms of other species. 
Linnaeus ( loc . cit .) gives its home as in Virginia, and adds that the plant has migrated thence into England. 
Europe (but perhaps not indigenous).
