FUMARIA 187 
( d ) F. officinalis var. wirtgeni Haussknecht in Flora Ivi, 409 (1873); Pugsley Fum. Brit. 52 (1912); F. 
wirtgeni Koch Syn. ed. 2, 1018 (1845). 
Exsiccata : — Dorfler, 4601, as F. wirtgeni ; herb. Pugsley, 248, 255. 
Shoot variable but usually slender. Racemes rather lax, 10 — 20-flowered. Fruiting pedicels 
about as long as the bracts or a little longer, generally shorter and thicker than in the preceding 
varieties. Sepals often acute rather than acuminate, whitish, about 2 mm. long and 1 broad. Corolla 
not deeply coloured, about 7 mm. long ; upper petal emarginate and lower one truncate-spathulate 
owing to the development of the broad wings about the apex. Fruit rounded — truncate above, 
frequently with a small persistent apiculus, broadest about the middle, narrowed below to a less 
obscure neck than in the preceding varieties, 2 - o — 2 ’5 mm. long and equally broad. 
This resembles var. minor in its short racemes and rather small flowers ; but it is frequently rampant in habit. It also 
has narrower leaf-segments, conspicuously broadly winged corollas, and differently shaped roundish fruits. The combination 
of these features has sometimes caused it to be mistaken for F. vaillanti. 
Jersey; southern England; and co. Meath, in Ireland. 
Germany, France, Austria. 
A weed of gardens and arable land, often very abundant ; throughout almost the whole of the 
British Islands, northwards to Orkney, though rather local or rare in parts of Ireland. 
Throughout Europe except northern Scandinavia and northern Russia; Asia Minor; northern 
Africa and the Canary Islands ; adventitious in America. 
F. muralis subsp. boraei x officinalis (see page 183). 
F. officinalis x parvifiora Pugsley Fum. Brit. 50 (1912). 
Exsiccata : — Herb. Pugsley, 276. 
Shoot extremely luxuriant. Stems slender, excessively branched, interlacing. Leaves resembling 
those of F. officinalis in form but very much dwarfer and with the segments frequently obtuse. 
Racemes with 6 — 20 flowers, exceeding the short peduncles. Bracts linear-oblong, cuspidate. Pedicels 
fully twice as long as the bracts, suberect. Sepals ovate-lanceolate, obscurely dentate, acuminate, 
i ’5 — 2 - o mm. long and 075 broad. Corolla coloured nearly as in F. officinalis but paler, 6 mm. 
long ; wings of the upper petal narrow and falling short of the keel ; lower petal subspathulate 
with narrow, obscurely spreading margins. Fruit quite abortive. 
This putative hybrid was collected at Mickleham, Surrey, in 1910, growing in company with the reputed parents. It 
occurred as an isolated plant, of enormous size, but entirely barren. It is noteworthy that its bracts are shorter and its 
outer petals much more narrowly winged than those of either F. officinalis or F. parvifiora. 
A putative hybrid of F. officinalis var. wirtgeni and F. vaillanti var. chavini (x F. alberti Rouy et Foucaud op. cit. 178) 
is recorded for France.

9. F. vaillanti (see below). Leaf-segments flat. Racemes shortly peduncled. Bracts shorter 
than the fruiting pedicels. Corolla pink. Fruit obscurely keeled, rounded-obtuse. 
10. F. parvifiora (p. 189). Leaf-segments normally channelled. Racemes subsessile. Bracts 
equalling or exceeding the fruiting pedicels. Corolla white, sometimes flushed with pink. Fruit 
distinctly keeled, mucronulate or shortly beaked.

Stem suberect, rarely if ever climbing. Leaves usually glaucous; leaflets with flat, linear-oblong
