RUMEX

R. pulcher x rupestris nobis; Trimen in Journ. Bot. xvii, 251 (1879) nomen. 
A specimen by Briggs (in Herb. Mus. Brit.) differs from R. pulcher in its strongly trigranulate 
fruiting segments, and from R. rupestris in its narrower laminae, its more divaricating branches 
of the inflorescence, and in its dentate fruiting segments.

British species of Sanguinei 
11. R. glomeratus (see below). Inflorescence more or less leafy almost to the top, branches 
ascending or spreading. Fruiting segments with 3 tubercles. 
12. R. rupestris (p. 145). Inflorescence leafy towards the base, leaves rather large, branches 
suberect. Fruiting segments with 3 prominent tubercles. 
13. *R. sanguineus (p. 145). Whole plant with very conspicuous dark crimson veins even 
when young. Inflorescence not leafy. Fruiting segments with 3 tubercles. 
14. R. condylodes (p. 146). Inflorescence not leafy. Fruiting segments with only 1 tubercle.

Two sheets named Rumex acutus are in the Linnaean herbarium : the specimens belong to this species, 
and were supplied by Loefling (no. 277) from Spain (“ = L. acutum Miller”). 
Perennial. Stem 4 — 8 dm. high, often more or less zigzag, branched from the base, branches 
slender. Petioles of the ground-leaves about one-third the length of the laminae. Laminae of 
the ground-leaves about 6 dm. long, lanceolate-acute, obliquely subcordate or rounded at the base, 
rather undulate, subentire ; of the stem-leaves, linear-lanceolate, acute ; of the inflorescence, almost 
sessile, linear, more crenulate. Inflorescence lax, leafy almost to the top, branched, branches ascending 
or wide-spreading, whorls distant. Flowers July and August. Anthers pale cream-coloured before 
dehiscence, pollen nearly white. Fruiting segments linear-oblong, margin entire or with only a 
few denticulations near the base, nearly 3 mm. long, each with a conspicuous oval tubercle. 
Achenes broadly ovate, reddish brown, and only about half the size of those of R. condylodes. 
The synonyms cited by Linnaeus (Sp. PI. 335 (1753)), and also the specimen in his herbarium, show that he included 
this species in his Rumex acutus ; but, as his diagnosis refers to some other plant, we pass over his name in favour of 
Schreber’s R. glomeratus. We deem it wise to adopt the rule not to accept a Linnaean name for a plant whenever the 
diagnosis which follows that name is quite inapplicable to that plant. The case of R. glomeratus is paralleled by those of 
Rumex aquaticus and Chenopodium serotinum. 
The plant named R. conglomeratus var. subsimplex by Trimen (in Journ. Bot. xv, 134 (1877)) is simply a small state. 
If names be retained for states such as this, almost every species would require to be divided into innumerable formae.
